Best gas conversion video on TH-cam!
Thanks for the vote of confidence, Mark. I've seen some of the other videos out there, SCARY! There are likely other's out there who know what they're doing, but they're NOT on TH-cam as far as I can see. Doing a fuel conversion is usually a simple affair. I've converted just about every type of bar-b-que and stove made. I'm now in the Midwest, so feel free to contact me at 714-574-1544.
You do good work. Thanks.
Wow that was very awesome! I’m glad you took the time to explain how time involved of a procedure this is and what’s involved.
I actually sell orifices for every stove and barbecue made on my website flamesources.com/ I'm now in the Midwest, and you can always get a hold of me at 714-574-1544.
Great video! Thanks!!!
I got a furnace in switching to lp no kit available being the age of it. Do you know if I need the same length of Orifice or can I use some that are like what you have or a plug type looking orifice?
much respect to you i deal with food service equipment and this is an art and science.

Kudos to you. I've certainly done my share of commercial equipment for restaurant and food wagons.
Frank I have a Weber Spirit NG grill can it be converter to propane? If it can where do I buy the parts to do it?
for steel(316) holes which drill bit required...carbidr drill bit or hss twist drill bit?
Awesome job thank you
What size orifice do i need for a Dearborn DRC-25A N? Someone converted this room heater to propane but I want to use natural gas.
Thanks for sharing your expertise.
great instructional video.
Thanks.
Hey frank thanks for the reply. We put a water heater in for my bosses Ex wife and we didn’t realize she had propane. Total nightmare. Thanks again
I've done propane water heaters before. Let me know if you can't source the parts to do this conversion. You can always call me at 714-574-1544.
I have an AO Smith water heater that I want to switch from propane to natural gas. What is the orifice size and where is it located?
Thanks for your help. We are currently talking with you on eBay about changing from propane to natural gas. Our shove is a Kitchen Aid. Vikki and Elmer

Hi, great information. Thank you.
How do I calculate what the proper final orifice hole size should be? I am converting an outdoor turkey fryer burner, older nice heavy cast iron burner that is currently. propane, converting to natural gas? Later, I would like to ask about required plumbing pipe diameter volume/pressure and regulator type/size. Thank you for sharing.
Doing a fuel conversion is usually a simple affair. I've converted just about every type of barbeque and stove made. I'm now in the Midwest, so feel free to contact me at 714-574-1544.
There are plenty of orifice calculators on the internet. Unfortunately, to do it safely, you'll need to know the actual BTU of your burners because manufacturers often lie about the true BTU of their burner systems. To do this, you'll need the numbers stamped on the orifice and output of your current fuel regulator. This will enable you to calculate the actual BTU of that burner. Typically, a burner is typically about 8 to 10 percent less than what the stated value is. So a burner rated at ten 10,000 BTU would actually be about 9,200 BTU.
To further complicate things, manufacturers often use a lesser BTU for propane than they do for natural gas. You'll usually see this stated on the label. However, this is not usually the case on commercial products.
Thanks for the Video,,, Sorry for the long entire but a lot to explain for a better understanding of the situation.., I have an Old Coleman 5600 Grill for the late 90's. I inherited from my father who passed away a few months ago...In my new home I have a nature gas line for an outdoor grill; I wish to use the grill in my home. On the units information label it has three different readings for (Lateral Btu of 13000) rating (Principal Btu 65000) rating and (Total 78000 btu) rating. Can you explain the need for all of the different rating and what are their meaning might be... It has a rotisserie on it,... Could that be why it has the different ratings for the different burners? If I wish to convert the unit from Propane to Nature Gas,,, Do I have to take these numbers into consideration when sizing the orifices, and make them different sizes for their applications?
Note: I have spoke to Coleman support offices, They do not recommend Converting the unit to Nature gas..
I have a VGIC485-6CSS range I am working on converting from Nat to LP.
I believe I need the #57 hooded orifices for this conversion. PB040036
I also need to flip the pressure regulator valve cap, to see LP on the cap.
I also need to adjust the air/gas ration door on the burner assembly to control and get a nice flame, at low setting. The gas knob, after it's been removed has an adjuster screws that controls the flame also.
Is there anything I missed that would cause a problem when converting this stove from Nat to LP?
I've done a load of Viking conversions. You're likely right on the size, but I'll need some info from the manufacturer's tag because those burners have a different rating from gas to propane. Feel free to call me at 714-574-1544.
At 5:30, when the world ends, he doesn’t skip a beat. True professional ;)

Good morning frank a have a phoenix http 80 gallon propane water heater. It's a commercial. I want to converted to gas and use it at home.The water heater has PVC piping. Is there a way to install it at home.
I have an outdoor gourmet 6 burner grill and want to convert to NG. do you know the drill size? also can I jus tie into line without regulator? any help would be great. line only has about 1-3 psi on it
I've heard a lot of people who say their gas guy told them to run their grille without a regulator. But think about it, you have a regulator on your oven and stove in your kitchen, so why would you run a grille without a regulator? The regulator is designed to shut off if you develop a leak further upstream and to "open loop." I do a lot of NG conversions where I figure out orifice sizes, but I don't ever give advice to people unless they are customers due to all the variables involved. The reason that orifice conversion kits aren't available from manufacturer's is because, by and large, they lie about the true output of their burners. So if you try to convert a grille based on manufacturer info, you'll likely be off in your calculations. Here's a link to an orifice chart that might guide you in the right direction: andersonforrester.com/conversion-chart/
Hey Frank I have the opportunity to get a great deal on a 2016 Weber S670NG grill but I want to convert it to L.P. Would you have what I need to be able to do that?
Yes. I've done a ton of those 670s. Just give me a call at 714-574-1544. Remember when you call that I'm on the West Coast.
Hello Frank, I'm building a food truck/mobile catering kitchen. I have a Vulcan deep fryer that was already converted to LP when I bought it, but I also have a Vulcan 6 burner range w/ conventional stove currently set up for Natural Gas. I purchased the correct LP conversion kit from dvorson for the model of range I have, it came with new burner orifices, regulator, and oven orifices. Seems like a fairly straight-forward kit, but I have had some difficulty finding someone in my area (KY) that has experience converting commercial kitchen equipment to LP. Have you done any commercial range conversions to LP, or can you give me any tips/advice.
I actually sell orifices for every stove and barbecue made on my website flamesources.com/ I'm now in the Midwest, and you can always get a hold of me at 714-574-1544.
I've converted everything from commercial stoves to backyard barbecues. This video shows the basics of doing a barbecue conversion. Aside from the info in this video, the best information that I can pass on is to make sure the BTU rating is accurate. I always reverse calculate the BTU rating on a unit before conversion because it's an industry practice to publish a BTU rating higher than what the raw flame source is capable of. I suspect the reason for this is to account for the residual heat produced by oven walls, grille grates, etc. To reverse calculate, check to see what orifice size was originally used by the number stamped on the orifice or gauging it with a drill bit, then compare the orifice size to a BTU chart that matches the output rating of your regulator. The BTU indicated by that chart is the ACTUAL BTU released by the flame source. Most commercial units use adjustable regulators to compensate for any discrepancy in the fuel source, altitude differential, etc. Since you're using a commercial unit like the Hart/Vulcan, the flame source is likely around 30,000 BTU, so a slight discrepancy in the flame source is not super critical, but it is a factor to keep in mind when undertaking the conversion. In my mind, accuracy is the key to maintaining the equipment especially considering the extra soot produced by an out of tune flame.
When choosing an orifice size what percentage of difference is the between NG and LP? I sometimes get appliances where there is no manual. It would be nice to pull an orifice from an NG burner and know what percentage smaller is right for LP.
Since manufacturer's burner ratings are usually inflated, I always reverse calculate the heat rating to get an accurate answer using charts from Ward Burner systems. I then forward calculate that heat rating to get my final orifice size for the alternate fuel. Some manufacturers publish cooler burner ratings on the propane side on the manufacturer's labels. I first figure out the propane rating based on the percentage that the natural gas rating is off by. So, if the calculated natural gas rating is off by 5%, I calculate the manufacture's heat rating to 5% less (of the number published on the manufacturer's label) to get a pretty accurate final heat rating number. I then calculate the proper orifice size based on that number.
Hi Frank, I've got a Uniflame propane bbq in Canada that wasn't made to be converted (no conversion kit). I think if the orifice holes are enlarged and I change the gas regulator, I should be able to run it on natural gas. Can you enlarge the holes in the orifices if I send them your way?
Did you try this out? I am curious if it worked out for you 2 years later?
I'm working on converting from natural gas to liquid propane and find I need orifices specifically for LP gas... where would I buy these from? This is for a GE Built In oven.
I carry those orifices, just call me at 715-574-1544. Remember that I'm on the West Coast when you call.
Hi Frank, I have a Jenn Air 730-0339 bbq that I am wanting to convert to LP. When we bought it at Lowes the salesperson said we could get a conversion kit if we ever wanted to switch it from NG. I am not getting any cooperation from NEX grill who is now in control of parts. They are giving me the runaround and I have not been able to get the parts I need. Model 720-0339 is the LP model. I wanted to know if you might have a way to get the pieces I need?
I've done quite a few Jennaire grilles. That grille is likley similar to the 720 series grilles, only it has two additional stove style burners to the right. We should talk. I'm on the West Coast, so call me at 714-574-1544 during normal business hours 9 to 5.
Frank, I bought a Thermador they don't make the lp conversion anymore. It is a PDR486GDZS /03 do you make what I need?
Griddle model. Nice! I believe I have parts for every Thermador model made. If I don't, I can make them. Just call me 714-574-1544. Remember that I'm on the West Coast when you call.
what do you have to do to change a hot water tank from Lp to natural gas
Hey buddy I'm trying to make a natural gas commercial fryer to propane any advice??
I got the hoses and regulator for a propane tank. I need to change something else??
Leonel Villamil I recently did orifices for a commercial Cecilware 4-burner fryer. Those fryers usually have their own regulators depending on if they're commercial or not. Feel free to call me at 7145741544.
Frank, i have a LP smoker that i want to change to NG. would you be able to make that possible? I really am tired of the propane having to be filled all the time and i already have a NG line ran with a quick connect on my porch where my smoker sits.. if you can make this happen it would be greatly appreciated. its only a single burner style vertical smoker. the burner looks like the kind that you would find on the older NG stove tops in your house. if that helps. please let me know if you can do this. thank you for your time.
I likely have an orifice to fit that unit. Just give me a call at 714-574-1544.
Hi, great information. Thank you.
How do I calculate what the proper final orifice hole size should be? I am converting an outdoor turkey fryer burner, older nice heavy cast iron burner that is currently. propane, converting to natural gas?

Hey Frank, I imported by Char-Broil grill from the US to the Netherlands. It is orginally a natural gas grill with a Rotisseri burner at 12000BTU/HR and 3 main burners at 51000BTU/HR. I will connect it to a propane gas tank, as that is just the way they do it in the Netherlands. I think the current orifices are just a little below 2mm (my 2mm drill just doesn't fit). What size of orifice would I need for the propane gas? And would it work if I just close the hole with some tin solder and re-open it with the proper drill? Thanks, Peter.
Doing a fuel conversion is usually a simple affair. I've converted just about every type of barbecue and stove made and have all the parts. I'm now in the Midwest, so feel free to contact me during normal Midwest business hours at 714-574-1544.
I'm always leery of solder fixes on orifices because solder is not as consistent as brass when it comes to machining. Remember, you're playing with fire here. You'll want to replace those orifices with new ones bored with proper holes drilled into them to match the ACTUAL BTU rating of those burners. I say ACTUAL because the industry at large tends to embellish their BTU ratings on their equipment. If you calculate the BTU rating on your grille you'll typically find that the BTU is typically 10% less than advertised. Also, a propane burner should ideally be dialed in to output approximately 8% to 10% less heat than the ACTUAL BTU of a natural gas burner. This is industry standard practice.
The other thing you'll need to consider is that not all regulators are equal. Some regulators are designed to output up to 1 PSI which translates to 27 inches of water column (WC). Ideally, on a barbecue, you should be using a regulator rated at 11" WC.
Here's a link to a chart to help you determine what size those orifices should be: qph.fs.quoracdn.net/main-qimg-3062426641a19445a92ccaad0b1320a1
Frank I have a Thermador PRG366EG oven and I want to convert LP from Natural gas. do you know the conversion kit?
or if it's possible?? thanks!!
I have kits for a host of different Thermador units. I'll need to verify the orifices in the top side burners. Can you send me an overall pic of the unit, then pics of the top side burners specifically, and a shot of the manufacturer's plate on the unit. I'll need you to pull an orifice from one of the top burners and send a picture of it as well. I have a video on converting a Themador at th-cam.com/video/nY749eSRECI/w-d-xo.html
I'm pretty sure I know what orifice the oven uses for the broiler and main burner. The broiler will likely use a pointed orifice, and the oven will likely use a large flat orifice. You can gain access to the broiler orifices through the back of the oven. The main oven orifice can be accessed by removing the oven floor and accessing it from the entrance of the main burner tube.
Feel free to send the pics to my mobile. Remember that I'm on the West Coast if you call. You can reach me at 714-574-1544. Make sure to state what model you're converting and to which gas you're converting.
Great info! Right now I’m struggling to find the original NG orifices that came with my 4 year old stove. It looks as if the installers took the parts with them when they converted it to LP and now Natural Gas is available in our neighborhood so I want to switch! GE can only sell me the gas tube assemblies with the orifices in them.
I actually sell orifices for every stove and barbecue made on my website flamesources.com/ I'm now in the Midwest, and you can always get a hold of me at 714-574-1544.
Hi, do you have the blank orifices for a Jenn-air 720-0727? I bought one that is NG and I need to convert back to propane. Thanks!
Yes. I've done quite a few of these Jennaire units, however I'll need to machine some more rotisserie jets because I'm out at the moment. I'm on the West Coast, so feel free to buzz me during normal business hours 9-5 at 714-574-1544.
If I want to switch my propane outdoor fire pit to natural gas (or vise versa) could I use the same tools/ methods as you do in the video?
Computers You can, however you'll want to go conservative with the orifice bores because usually BTU ratings are inaccurate and the true equivalency is not accurate as well when it comes down to doing a conversion. I stay away from doing fire pits for this very reason, and you're likely better off replacing the pit altogether. If you still decide to pursue a conversion, you'll need to swap the regulator as well. If you subscribe to my channel, you'll be able to view my video on fuel regulators. Bottom line is that fire pits and gas barbeque log conversions are a huge liability.
Hello Frank I would like to convert a Blackstone 28" Griddle fron LP to Natural Gas... can it be done and how big i would have to drill the hole in the orfice?? thank you!
Here's the conversion chart that you'll need to do the job: andersonforrester.com/conversion-chart/
Frank I have a ICV- Imperial convection oven could you guide me on how to convert it? how much would your kit cost?
I'd have to see the orifices. Why don't you give me a call at 714-574-1544.
Frank:
Interesting video. Do you sell the gas orifices for gas grill conversions? I have a Weber E330 that I need to convert from NG to PG. Thanks. Will.
I've done quite a few late model Weber Grilles lately. I believe that those are 1/4-inch orifices. I'll be turning out a batch of those on my lathe this weekend, so give me a call at 714-574-1544.
Hello Frank I am trying to convert a frigidaire cooktop to LP and the kit is no longer available. Is it possible to get the correct offices and do it myself?
I have orifices for everything made. Just call me at 714-574-1544.
Hi, great video, I have a 21000 btu char broil using propane, I want to convert to natural gas...do you know what size orifices I would need , what drill size to use? I just have two burners. They look like screw type and very small. Thanks in advance Frank.
Manufacturer's burner ratings are usually inflated, especially on Bar-b-cues. I usually reverse calculate to find out the heat rating, then translate that to the proper bore using the other gas and output rating. I use very specific data to hand calculate my solutions, but I can recommend a general user friendly chart instead. Here's a chart that Anderson Forester has published: andersonforrester.com/conversion-chart/
Know anything about the old Martin U-1116 gas heaters? Found one brand new that had been stored for decades, would like to convert it to propane, but the burner has about 100 holes...
The burner is likely fed a steady gas supply by a single orifice or multiple orifices. I've done orifices for just about everything made, so feel free to contact me. I've moved to the Midwest , and you can always get a hold of me during normal Midwest business hours at 714-574-1544.
I have a summit rg244w stove it is currently set up for lp need to covert it back to ng . Do you have these orifices or can i drill out the lp ones .
Thanks for your interest. I have orifices for everything made. Feel free to give me a call at 714-574-1544. Make sure to call during normal West Coast business hours.
I have a Char-Broil Commercial NG that I'm converting to LP. The NG version comes with no orifices - manifold straight to burner. How do I know which size orifice to use. I know that the orifice head is 9/16 socket size and the bore hole should be #133 or a 55 bit. Just not sure about thread width/size.
Here's a chart published by Johnstone Supply: www.johnstonesupply.com/storefront/tools/orificeChart.ep As rule, Propane orifices have smaller holes than natural gas orifices. I have orifices for everything made, so feel free to contact me at 714-574-1544. Remember that I'm on the West Coast, so call during normal business hours of 9 a.m. to 5 p.m. Pacific Standard time.
Looking for help I am trying to convert my Jenn-Air Dual fuel range to propane but they no longer sell the orifices the part is 12002473 for model # JDR8895AAS, do you know what size the holes should be for propane?
Propane sizes are smaller than natural gas sizes. I've done a few thousand of these Jennaire units, but never the JDR model. Maybe you can send photos to my mobile at 714-574-1544. I'd like to see an overall shot of the unit, but the more critical photos would be of the manufacturer's tag and the numbers stamped onto your current orifices.

hey frank i need for my magic chef Gas Range model #8261rv a Conversion Kit to an lpg what you regamend iam bast in overseas thank ut
So in order to convert from LP to NG I would need a new larger orifice and a different regulator? I wouldn’t have to change out the burner itself right? I’m thinking of converting an old burner I have to NG. The burner was found at the local dump and the orifice is missing.
Most regulators are convertible between natural gas and propane. The orifices will need to be tailored to suit the type of fuel that you're using. Here's a conversion chart to use if you know the BTU rating of your burner: andersonforrester.com/conversion-chart/ The burner itself will not need to be swapped, however the amount of fuel that travels up the burner tube will need to be altered to balance out the recommended air/fuel ratio required to make that burner operate as designed. This is usually achieved by adjusting an air adjustment commonly found on most burners. Doing a fuel conversion is usually a simple affair. I've converted just about every type of bar-b-que and stove made. I'm on the West Coast, so feel free to contact me at 714-574-1544.
howdy. I have a 46" dacor drop in cook top that had the igniter melt down. I bought a totally new replacement unit and now have the old one sitting in my garage. Would you like to refurbish it?
Yes, I would love to refurbish the unit. I've done rehabs and conversions on many different unit in the past, but the Dacor brand is the best. Feel free to call me at 714-574-1544. Remember, I'm in the West Coast time zone, so call during normal business hours.
Hi Frank! I have a mid century universal chef by waste king, its a comercial 6 burner range, oven, flat top broiler combo. I need to go fron NAT to LP, Im having trouble finding any info, let alone a conversation kit! Any chance you may be able to help?
I've done quite a few of these vintage units, so I likely have the parts for them. Just give me a call tomorrow after noon, and we'll figure out what you'll need - 714-574-1544.
Do you have orifices for the Camp Chef Flat Top Grills/Griddles?
I have orifices for everything made. I'm on the West Coast, so feel free to contact me during normal business hours at 714-574-1544.
What's your thoughts about a Mr. Reddy Propane Forced Air Heater 75-125K BTU conversion to Natural Gas ? Thank you.
I've done similar units. Naturally, the orifices need to be swapped, but parts of the control unit also need to be swapped. Feel free to call me, 714-574-1544.
Hi Frank. Can you point me to a conversion chart for altitude? Looking to buy a Samsung gas cooktop, convert it to propane (comes with the propane orifices) and then get it set properly for my 8300 ft. elevation.
The altitude factor for 8300 ft. is 0.8860. Without any other adjustments, this means that the BTU rating of your burners will be reduced by a factor of 0.1140 without any further modifications. I've done high altitude conversions before, and they can be tricky, usually involving a combination of manipulating orifice sizes and output ratings of the fuel regulator. You're regulator's output is likely 10" WC, so it might behoove you to get an adjustable fuel regulator for propane only. This should allow you to get close to what you'll need to balance everything out for your high altitude environment. It's mainly the low gas settings that you'll be concerned with and the high gas burner ratings will likely be less than what you'd expect to see at sea level.
Hi Frank, I have an old Garland 10 burner range that I want to covert from NG to LP, what size orifice should I use? Thanks!!
I actually sell orifices for every stove and barbecue made on my website flamesources.com/ I'm now in the Midwest, and you can always get a hold of me at 714-574-1544.
In many cases, those vintage stoves were "field convertible," meaning that the orifices were simply adjustable to convert from one gas to another. Here's a link to a video that explains this type of orifice: th-cam.com/video/JzcZ-yskLxA/w-d-xo.html Make sure to "like" and "subscribe to my video channel when you visit.
The wedges that were used on these orifices fall into two categories: those that are blanks and those with specific holes in them to exactly flow the correct amount of fuel once the orifice body is jammed onto them. On an older stove like that garland, it's possible that the wedge IS NOT bored, so you may need to adjust it to flow the correct amount of fuel. Keep in mind that the end result should be a well balanced flame.
Hi Frank I have a Napolean BIP500 Natural gas built in grill and need to convert it to propane. Do you have the orifices and regulator for this grill.
Yes, I've done several Napolean grilles, so I likely have the parts. I have orifices for everything made, so feel free to call me at 714-574-1544.
Do the holes in the orifices need to be smaller for propane? I need to convert to propane but the orifices for my maytag mgr5775qds are no longer available and i cant find any so what could i do?
Yes, generally speaking propane holes are smaller than natural gas holes. I have orifices to fit every application there is, including Maytag/Frigidaire, so feel free to call me at 714-574-1544. Remember, I'm on the West Coast when you call, so call during normal business hours.
Hello, I am converting my gas range back to natural gas, I have all but one of the orifices. The burner I am missing the orifice for is rated at 12.5K BTU for natural gas. It currently has a 97 LP orifice installed. What size natural gas orifice do I need? Thanks
Here's an orifice conversion chart from Anderson Forrester: andersonforrester.com/conversion-chart/
Hey Frank how are you? I have a Roccbox Pizza oven that I want to change from LP to NG. Do you have a conversion available for that or would you be able to make me one? Thanks.
I've done parts for the Roccobox before. Just call me at 714-574-1544. You can also send me pics at that number.
Hi Frank. I have an early 1900's cast iron cook stove, similar to a Glenwood stove, that is supposedly set up for natural gas. I would like to convert it to propane. The stove has hooded orifices just like the one in your video. The number stamped on them is a 99 (or a 66), not sure if you read it right side up or upside down. Do you sell orifices with a smaller hole that I may use to replace the ones I have? I can't search your website because the brand is not listed. Any help would be appreciated.
Doing a fuel conversion is usually a simple affair. I've converted just about every type of barbeque and stove made. I'm now in the Midwest, so feel free to contact me at 714-574-1544. You can also visit my website, www.flamesources.com
good job
I'm trying to find Dyna-glo orifices which have an M8 1mm thread pitch. Can't find them anywhere. Any sources?
I've done Dyna-glo conversions before from the extensive inventory that I carry. Doing a fuel conversion is usually a simple affair. I've converted just about every type of barbecue and stove made. I'm now in the Midwest, so feel free to contact me at 714-574-1544.
Awesome video. I have a Weber summit S-420 I am converting. What drill bit size would you use for this 12000 BTU model. I have a numbered drill set and a hand drill.
Also do I need a NG regulator. I read it both ways. Some say yes some no.
Some states require the use of a fuel regulator on an outdoor grille, some do not. I'm all about best practices, so I always recommend a regulator. This is your last line of defense. Typically, a fuel regulator is designed to shut off the fuel supply if the system developes a gas leak and goes open loop. The very use of such will determine the input rating of the fuel supply and will affect the final bore size of your orifices. I've likely done 30,000 or 40,000 Weber grilles at this point in my career. Anderson Forester has a nice chart that's easy to understand, so you can find it on the web. One more thing. Weber ratings on their burners is inaccurate, so dont take those numbers as gospel. It turns out, this is a rampant industry practice, so all grille manufactures do it except for Jennaire. I carry all manner of orifices for everything made, so feel free to call during normal West Coast business hours - 714-574-1544.

Hello Frank, I have a one year old AO Smith water heater that I'm going to have to convert from LP to NG, is that doable? Thx
Doing a fuel conversion is usually a simple affair. I've converted just about every type of barbecue and stove made. I'm now in the Midwest, so feel free to contact me at 714-574-1544.
Having said that, I've also done water heaters from time to time. There's a chance that the parts on your unit are custom. In which case, I would need to fabricate parts on my lathe. Also, that unit likely has a pilot generator/regulator which would require a different regulator component. Traditionally, a majority of these units were made by Robertshaw and Honeywell, but a host of other companies have entered the market, so we'll need to analyze what system controls your unit.
Hi Frank. Where did you get your drill bit set and how much do they cost...if you don't mind me asking? I have only done one gas range and it's not done yet so I'm not your competition. i'm just looking for a good set of drill bits for drilling steel. Just an fyi there.
I got the large drill set from Harbor Freight Tools and the little drill index from McFaddendale Hardware. Hope this helps.
Frank I have a weber grill E 210 NG and I want to convert it to PL, what do I need? do you sell the parts
I've converted a few thousand Weber Series grilles, but I haven't done a 210. Maybe you can pix message me. I'll need an overall shot of the grille, a shot of the manufacturer's label and shots of one of the orifices - from the top down and as a static side shot. You can pix message me at 714-574-1544.

Hi Frank, I've got a buck stove model 329 that is natural gas and I need it to be propane, Buck stove says it can't be done, can you help me? Thanks.
I'm always hesitant to give advice on heating devices and "gas" fireplaces because these items use an virtually uncontrolled flame in a visual and functional way. That being said, in theory, anything can be converted. You'll need to change the regulator, the orifice and the pilot generator (if there is one).
Great video. Bought a blackstone 36” w/ airfryer. Says it’s not able to be converted to natural gas. If I bored out the holes by 1 or 2 drill sizes, do you think that would be enough? They say the airfryer won’t get to temp. I am at 6,000 feet altitude. Thank you in advance

I can only speak in generalities here because I don't know everything there is to know about your setup. Here's a link to a conversion table from Andersen Forrester: andersonforrester.com/conversion-chart/ This is oversimplifying what really needs to be done, but it will give you a general idea, albeit, there is the altitude to factor in. The charts I use take this into account, but those charts are not available on the internet. If I had to venture an educated guess, I would say that the orifice should likely be bored one size smaller than what would normally be calculated at sea level for this setup. But again, there may be other factors to consider.
To further complicate this situation, there's likely a deficit between the sated factory stated BTU of your unit and the actual BTU. You would really need to reverse calculate the numbers using the size of the current orifice for propane with the rated output of the regulator factoring in the altitude. If your grille uses propane with a small bottle mounted underneath, it's likely that regulator is rated at 11" WC. At any rate, you can see how such an endeavor (converting a grille to another gas) could become a slightly complex affair.
Hi frank i have a DCS RGS-305ss stove and want to convert it to propane are there any kits out there or do you know what orifices i would need thanks

Hi frank i bought a 3 valve griddle and i need to replace the valves. For 3 valve griddles is the orifice size 57?. Sorry but unfortunately there is no info on what brand it is as it’s completely gone . I plan to use propane. Thanks any info helps or maybe you sell the valves too.

You are so precise I would think you would put the orifice in a vise & then have the chuck mounted perpendicular to the orifice & then you can hand drill straight !
You likely missed the spirit of this video. I don't ever use a drill motor to bore orifice holes because these holes will distort under higher speeds. I use a pin vise to hold the drill bit while I'm boring it out to the final size. A precision job on the final size is only achieved by gradually creeping up to that size one bit at a time. I also bore holes in the custom orifices and jets that I make on my lathe at very low speeds. If I'm boring a much smaller hole (like a #87, for example), I'll do this in one operation, otherwise I'll still bore a pilot hole, then hand bore to larger sizes. Feel free to contact me during normal West Coast business hours at 714-574-1544.
Frank,
I have a Weber Genesis S-330 that I want to convert to LP . As you know, Weber doesn't sell conversion orifices. There are three burners a sear burner and a side burner. The literature says the main burners are 48000 BTUh. (3 main totaling 38000 plus the sear at 10000). Side burner is 12000. The main orifices remove with a 5/16" socket and the side burner uses a 9/32". Where can I find orifices that will fit?
Thanks - Tim
Weber heat ratings are always off, but you wouldn't know that until you've tried to convert one. I have the true ratings on most of their grilles, because I've converted most of their models. If I don't have the correct rating, I can calculate the true heat rating. I have an extensive inventory of orifices for the Weber product line. Just give me a call, and I'll put a kit together for you. I'm on the West Coast, so call me any time after 10:00 a.m. at 714-574-1544.

Hi Frank. I have a 2002 48" Dacor cooktop/oven. I am trying to change over from propane to natural gas. They no longer make the conversion kit. An appliance guy tried to get the orifice sizes from tech support and they wouldn't cooperate. Also said that other parts need to be changed as well and that you can't just change the orifices. Any help on what to do? To replace the unit it costs about 12,000. I need a better option.
I've converted more Dacor ranges than any other brand. I've got quite a few specialty parts exclusively for Dacor. I'm on the West Coast, so make sure you call me during normal business hours - 714-574-1544.

Yes, I do conversions on Weber grilles and I have the parts. Feel free to contact me at 714-574-1544.
I bought a storage unit with a Fryer in it. The mfg. placard is scratched up so bad I cant read it. Is there any way to tell if it is set up for LP or natural gas by looking at it?
Yes, the holes bored into the orifices and the regulator will give you an indicator of what it's equipped for. It's a little bit of a guessing game, but it can be done through various deductive methods. I have propane and natural gas conversions for everything made including industrial fryers. Feel free to call me at 714-574-1544.

It sounds like you're converting FROM natural gas TO propane. Either way, it sounds like you'll need to replace the orifices to get the type of flame you're looking for. I've likely done more than 60,000 grilles at this point, so I likely have the orifices you'll need to complete this conversion.
Frank. If converting from ng to lp, could you use a regulator to lower the lp to 7"wc and then not have to change it the orifices

This is a broad generality. It depends on where the numbers for the natural gas orifices fall as to whether this will work out or not. You would really need to reverse calculate the orifice sizes versus the rated output of the burners. You must also take into account that, as a rule, a manufacturer would design a propane solution to be 7 to 11 percent lower in BTU capability compared to that of a natural gas set up. And there again it totally depends on the manufacturer and the model.
Case in point, a normal rating for a a majority of Viking topside burners is 15,000 BTU, while the propane version of that same burner is 13,500 BTU. This means that the Viking rates their propane burners at 90 percent of what the natural gas burner is rated at. However, these are numbers published by Viking and Viking is interested in publishing numbers that make their product look like it outputs more heat that it actually does in practice. In actuality, if you calculate the heat rating by the numbers (factoring in the size of the bore of the orifices with the rated output of the regulator expressed in Inches of Water Column) that 15,000 BTU commonly calculates to around 13,800 to 13,950 or so. So you'd have to assume a 93 percent efficiency for that 13,500 BTU would factor out to 12,500.
There are very few manufacturer's who actually publish accurate numbers for their product. One of these products/manufacturers combination is the Jennair grille. I've found, over the years that, by and large, you can trust the numbers on a Jennair grille. I'm likely the only person in the industry who sticks to this practice, because, if you inadvertently have a fire caused by your appliance, and an investigator does his due diligence, it's possibly my ass on the line, and I NEVER do a conversion without seeing a shot of the manufacturer's label and the numbers stamped into the manufacturer's orifices.
I bought a 1920s wood/gas combination stove. The orifices must be for natural gas since when I connected a small propane bottle the flames seemed too high and yellow. Also, when more than one burner is lit the pressure drops off drastically. Any idea why this would happen?
The unit is set up with natural gas orifices, so those will need to be swapped for propane orifices. I have orifices for everything made, so you can always contact me if you need to change the orifices. You'll also need to convert the regulator if your regulator is convertible. Since this unit is a 1920s model, it might already be prepared for propane using the existing orifices. Many of these Depression era stoves are like this. You can view my video that explains this process with convertible orifices: th-cam.com/video/PNrBdLLvXPw/w-d-xo.html You'll also need to convert the regulator if it can handle both types of gases. My video shows the most common type of regulator in use today: th-cam.com/video/d2GljedOVaQ/w-d-xo.html If the regulator in the second video is not the type you have, you can view a more detailed video showing various types regulators; th-cam.com/video/AddrkTCBd7c/w-d-xo.html In either case, you'll have a little work to do to complete this conversion.

I am converting a NXR gas grill from LP to NG. What size does the orifice hole need to be? I have tools and numbered bits to change the size.
That's a very general question and there are several variables that will come into play here. I normally do conversions by calculation, but I can send you a chart instead that will assist you in this effort. Here's this link: andersonforrester.com/conversion-chart/
You'll need to backwards calculate the orifices and the rating for LP to find the actual BTU rating of your burners (as opposed to what the manufacturer says the BTU is). Once this is established, you can forward calculate the orifice size based on that BTU rating versus the output rating of the Natural Gas line your feeding the unit from. Keep in mind that many units have a different BTU rating for LP than they do for Natural Gas, so read your label carefully.
I have every orifice made, so feel free to call me if you need me to do this conversion for you at 714-574-1544. Call during normal West Coast business hours (9 to 5).
Hi Frank, we have bought a used Thermador PDR364GDZS, I am being told it can't be converted from natural gas to LP because the conversion kit is obsolete. We only have access to LP, would you be able to help us?

Hi Frank, I am converting a member Mark grill from natural to Propane, the grill say 18000 btu per orifice…what size orifice do I have to install to make it work? Thanks..

Generally speaking, propane orifices have a smaller hole in them than natural gas ones do, so, normally you'd need to swap in orifices with a smaller bore, then swap the fuel regulator to get the job done. There are only a few grilles on the market that support burner that are rated at 18,000 BTU per burner, and I seriously doubt that Members Mark is one of them. You'll need to look at the numbers stamped into your orifices to determine what the true BTU actually is per the rating on the fuel that your now using, then use the number that you've determined to be the actual BTU. Remember, manufacturer's usually inflate the actual BTU ratings on their burner systems.
Hello Frank..... Hears a question I doubt you have heard before.
We have a house in the US out in the country (West Virgina style). All around our farm there are Gas wells & Oil wells. On our farm there are 5 Oil wells. The oil wells also make some Gas. The gas BTU off the Oil wells is approx. 1,900 BTU.
Per. terms of the Oil lease we (the property owners) are entitled to free gas to our home. I would like to utilize the free gas but I'm unsure if Natural Gas Hot water heaters, Furnaces, Stoves & Dryers would operate correctly on the high ~1,900 BTU Gas without modifications.
I know manufactures make conversion kits from Nat. Gas to L.P. ....... But what about from normal Nat Gas (IE: 1050 BTU) to High 1900 BTU gas ....... but not as high as Propane @ 2500 BTU.
You sound like you might have some insight into my Issue.
Thanks,
RDS

Without any information, I can't actually give you a blanket recommendation on what size those orifices need to be bore to. I would definitely consider keeping the propane orifices in the event that you decide to move the unit to a place where propane is the norm.
Here's a link to an orifice boring chart from Anderson Forrester: andersonforrester.com/conversion-chart/
Keep in mind that the average burner is listed at 8% higher on the manufacturer's label than the actual output of what it's capable of. This is likely a marketing ploy by manufacturers to make their burners appear hotter than they actually are in the real world, so you'll want to bore your orifices to be 8% cooler than what they are advertised on the label. Also note that, in most cases, natural gas heat ratings are advertised as hotter on the label. If you look at the manufacturer's label on your unit, you'll likely see that is the case. There are few exceptions to this rule, but, by and large, this is the case with most manufacturers. Since GE is your manufacturer, that is definitely the case with the burner's vs the label on your unit.

Hi Frank, great video! I'm working on a propane oven and I am sometimes getting a flame in the air shutter. Is it possible that a dirty orpheus is causing this? Thankyou in advance for any help.
If the burner is making an unusual noise, then the cause is a perforation (leak) in the burner tube.
Hello Frank--
I bought a1966 O'keefe & Merritt gas stove and the seller was using propane gas; I have natural gas in my house. I've looked far and wide to buy replacement burner orifices for natural gas but coming up with none; my search leads me to believe that either the stove is too old and the orifices are no longer manufactured or that I'm looking for something that does not really exist.
The instruction manual that came with the stove (yes, the previous owner kept the original manual) references instructions on conversion from NG to LP as follows "... a) Non-pressure regulated models, screw oven, broiler, and top valve orifice hoods down until needle closes hole in hood and adjust air shutters... b) pressure regulated models, remove pressure regulator and use same procedure as in "a"."
On a prior paragraph, the manual reads "...All ranges are equipped with orifice needles with hole in them for LP gas. All ranges leave the factory adjusted for natural gas. On ranges with a pressure regulator, range is factory pre-adjusted; normally no adjustments are required."
I have verified at this point that the stove does not have a regulator at all (the instruction manual notes that some models are pressure regulated with the regulator placed at the end of the manifold (4" W.C. and 3/4" female I.P.S.) while others are without the regulator and the manifold end is 3/4" I.P.S); the gas line connects directly to the manifold WITHOUT a regulator in-between. The previous owner does not know if the stove was originally fit with a regulator; naturally, during the conversion to LP, the regulator would have been removed according to the instructions above.
I'm in the process of cleaning the stove (basically taking it apart and cleaning every nook and cranny--I'm eager to see to get the stove into my kitchen and working. As I said before, I have natural gas and I'm at the point where I have easy reach to the manifold and the burner valves; I'm there where the orifices are located but need help in determining what to do about them.
My questions are as follows: 1) is a regulator required for natural gas installation? I've seen them on line and they're not too expensive and can allow for "easy" conversion from NG to LP and vise-versa; mind you, I don't every plan in having LP. This is another question that I've researched on the internet and have not derived a clear answer.
2) do I need a different orifice that what the stove came equipped with? Is the adjustment in the conversion simply by tightening or loosening the orifice hood? The orifice hood bears markings of 52 and 68 on the sides...I'm not sure what these numbers mean or why there are two different numbers.
I apologize for the lengthy discourse; and I apologize too if the question is "dumb" but I'm learning as I go. Your help is truly appreciated.
