Changing the burner head on the oil furnace

- This one covers using the correct burner head for the nozzle size. This video is part of the heating and cooling series of training videos made to accompany my websites: www.graycoolingman.com and www.grayfurnaceman.com to pass on what I have learned in many years of service and repair. If you have suggestions or comments they are welcome.
If you are a homeowner looking to repair your own appliance, understand that the voltages can be lethal, the fuels are highly flammable and high pressures are used. Know your limits.
@grayfurnaceman: Your videos have been very helpful since I first had to troubleshoot my furnace on Christmas Day years ago!
I run a 1.1GHP - 80B nozzle on my Beckett AFG burner on a short barrel, heat exchanger, in a low-boy forced hot air furnace. Beckett says both the F6 & F12 combustion/flame retention heads are within range of the nozzle I run, but given the choice, I am inclined to always run the smaller slot sized, F6 head, so I can run with a little more air pressure behind the head. The original head was an F12, and I had to run the burner with the fresh air intake almost entirely closed to get the air setting correct.
I learn a lot from your videos. Thank you.
Hi I’m gas furnace guy,,you are teaching me so much about oil furnaces,,,,thank you. You are a very patient and great knowledgeable instructor. Better than the teachers I had in school. I think some of them only had like 3 year in field training and became teachers.
You are a Master! You are a dying breed...Salute to you Sir
Thanks for the support.

Great job explaining bud. Thank you.
I TAKE MY HAT OFF FOR THIS VIDEO. IT SURE IS VERY INFORMATIVE. I WISH YOU COULD EXPLAIN THE OTHER ADJUSTMENTS NEEDED TO DO WHENEVER DOWNSIZING/UPSIZING A NOZZLE FLOW CAPACITY FOR A BETTER BURNER EFFICIENCY. THANKS SO MUCH FOR YOUR TIME. A++
I will have something coming out in Feb. Hope it helps.
GFM
,,,,,,,,Thank you ....for the engineering level of facts about what many think is simplistic....

Nice job, thanks for sharing
Thanks for the support. More coming on furnace efficiency.
GFM
Great videos. Thank you
good one, sir...
Nice one GFM.
some people are rude thanks great help
My furnace burners spark is grounding out at time, I assume because there's a carbon bridge that forms on the electrode tips. That would suggest the electrodes aren't adjusted properly but I believe I did because I used the gauge. The air is adjusted so there isn't any smoke. Do you think it could be the fire retention head causing this?
The gun depth is also crucial. You could be shorting to the head.
GFM
@@grayfurnaceman I've never adjusted the gun depth in the 12 years I've been servicing it. Could it move out of proper adjustment over time? The furnace is pushing 27 years old lol. I need a new one soon but I haven't decided what kind of unit to buy like propane, oil or heat pump.
@@samuelm370The slide where the gun line attaches to the burner may have come loose.
You could also have a combustion chamber breaking up.
The furnace may have many more years of good service.
GFM
@@grayfurnaceman another thing I should add. When the primary is tripped and I push the red button, the burner runs but no spark until I lift up on the transformer and that'll get the spark to light the oil.
As far as commercial furnaces go, shouldn't one just adhere to what the specs are for a nozzle/head combination? One would think with all the countless hours of research they put into their product, that they call out the most efficient combination?
The manufacturer's instructions are generally best to follow. However, oil is sometimes different in different locations. Most furnaces I have seen come with a solid nozzle. In my area we seldom use them. The hollow pattern works better on oil in my area.
GFM
Would a warped retention head potentially cause a Hard Lockout by obstructing the flame sensor?
It could.
GFM
the head doesn't regulate how much air goes through it the air adjustment does
Not altogether true. The burner head is there to control the amount and distribution of combustion air in order to keep the flame near the head and concentrated to increase its temp.
This distribution and amount is different for different nozzle sizes. The air adjustment essentially fine tunes the amount of combustion air.
GFM
grayfurnaceman these heads are designed for a certain amount of firing ranges you're going to tell me that you introduced the same amount of air through the air bands and let the head control the air that's delivered not this had controls only the air is delivered to the fuel it's being sprayed to make sure it's burnt efficiently
You are making a very simple issue into something complicated. You put the right head for the nozzle size, the adjust your air.
Also, if you want to be taken seriously when commenting, use punctuation. Your last comment was almost unreadable. Remember, the point of writing is to communicate effectively.
GFM
My oil burner man is telling me I have a cracked retention head, Is that possible? How much should that cost?
It is. The head itself is about $25. The labor to replace is high as is the service and adjustments made to keep it from happening again must be done.
GFM
grayfurnaceman Where do you get these different restrictor plates and different heads online please? Thank you!
@@Doing_it_right_the_first_time I don't have any trusted sources, but they are available online.
GFM
grayfurnaceman Well can’t you at least tell me where you get yours? Thank you.

What BTU rating is the oil furnace you setting this up for?
Walter Null Its a 60 to 75000 BTU unit.
