It’s the season! Was working on a snowy roof yesterday!

Typically in a commercial contract we own installing the duct smoke detector but the electrician provides the detectors and also wires it as well.

Nice, haven’t been able to try those out yet.

I think that’s a very ignorant comment to say it’s a “let down”. Im a sheetmetal mechanical not an electrician. This is as far as a sheetmetal mechanic goes as to installing one of these.

Tends to be on many Electrictians contracts.

@@Truthh4040 fortunately I’m not an electrician and never really looking into the wiring diagram. I’m sure I can figure it out and maybe post a video and share to you

@@SheetmetalHVAC__ thank you it’s probably simple but just don’t wanna make mistake and damage the unit.. manual just not clear

Riveting hammer

@@michaelhinchey sorry for the late response. It’s kind of a “feel” thing if you can tell there’s a lot of weight on it and it’s sagging I would go through the whole thing

I do it like this, but I use the excess strap as leverage to adjust my strap to get it Uber tight, no tunnels on my strap. Good job do, everyone has their way 👏 👍

@@kennylopez8965 yes of course, so it can actually function. Proper install is also important for it to function properly. Any installation process of a life safety device should be important.

Thanks for the tip I’ll have to do that next time

Yes you right! I remember my Forman at the time showing me that I learnt that maybe 7 years into this career. I don’t really use that technique much

I used to use one just felt super bulky in my tool belt so I would run the 6” but now I just upgraded to another brand that’s 8”

I’m glad my experience is getting shared with future mechanics thank you for watching and sharing my videos!

Yes you are correct or another option is the way I did it in the video and you don’t need to do the math on any size duct and don’t need to mark anything at all. So many ways to accomplish one job. Thanks for watching the video!

Hi Karla the lift is a genie lift also know as an “air lift” the lift uses carbon dioxide to erect the lift.

Hi sorry for the late response hopefully you were able to get an answer for this if this was urgent. To answer your questions, first off I have not installed that particular brand but they are all pretty similar. I always recommend installing any equipment per manufacturer’s instructions. There are two tubes. A test tube and an exhaust tube. The test tube should always be before the exhaust tube and holes should be facing against the airflow so air can go in the tube with the holes. The small pipe that comes with the equipment is the exhaust tube so the air that goes in the device can be exhausted out. Some brands say the tube should go through and some say you can stop two inches before the duct. It depends on the length of the test tube, if it’s too long it can break from the housing. So the smaller one doesn’t need to be extended because it’s just an exhaust tube. The point of this device is to get a test sample of the air to go inside the sealed enclosure which has a smoke sensor and then the air gets exhausted out by another tube being the smaller one. There’s no pumps involved so it’s important to install the tubes correctly.

@@SheetmetalHVAC__ Thank you for your detailed response it was very helpful!

If we are talking snips you are correct Midwest are the best! I use dividers in the field if I need to make a round damper. It’s also commonly used when fabricating any collars or square to round. It’s good when you’re bisecting a pattern or finding true length.

I have always called them slips or a slips and if it’s not a four sided slip connection I call it a slip and drive connection. But the way I was taught is that the connections of duct really depend on preference but its very common in residential because that’s what most supply houses sell from what I’ve noticed. The purpose of the drives which are usually on the left and right of the connections is to basically lock the two pieces together. I’ve demoed a lot of duct where people don’t even use screws just use the drives. A slip and drive connection is going to leak a lot more air which requires a bit more duct seal. I think slip and drive connections are quicker than all slip which is nice. On this specific project the engineers did not allow slip and drive connections they required all slip or TDC or TDF connections.

@@SheetmetalHVAC__ thank you. I hope you post more videos 😊 For some reason, there are not many sheet metal workers on youtube 🤔

Hey what’s going on. I always appreciate when people suggest videos. I will put this on my list. I’ll see if I can work on a video this week and have it uploaded this weekend. Subscribe for updates and such. Much appreciated

@@SheetmetalHVAC__ forsure bro no rush, I’m a first year apprentice at local 104 so just adopting new working tips 🤘🏾

These pants are FXD pants and I have a carhartt knee pad insert. I can’t remember exactly what model for the pants

Nice right on I’ve used that method as well

The local in my area they don’t even know how to set hangers. There’s a guy dedicated to just setting hangers. The whole job stops if they arnt on site and the mechanics catch up. Pretty sad. And if the mechanic starts setting hangers they get yelled at because they are taking someone else’s job so they stand around until they go home.

Local 105 right here 🤝🙏

I don’t own one but the company I work for just bought three of them I’ll have to try it out.

@@SheetmetalHVAC__ Nice! we're doing a 20t rtu all spiral shutdown - nights this weekend I just bought one yesterday Only problem we had with internal lined pipe the extruder has to penetrate an inch or so

@@taylorj9920 nice! I saw a video of someone using a nibbler that’s extended which was made for double wall

If you don’t know how to insulate around hangers your garbage at insulating. Our subs have no problem with our hangers.

Explain to me how you would set hangers on spiral duct. I appreciate the comment though helps boost my stuff 👍🏼👍🏼

Yall don't understand my man is the best metal worker in earth

I don’t know man it’s been working for me and many others for a long time. Instead of bashing on the way I do things why not explain how you do it so people can be educated on other ways to do things? If I just explained diameter times pi that doesn’t explain the other things needed. I’m just explaining my way that I make multiple hangers quickly and efficiently no one needs to follow me.

Very true

How do you cut pipe?

@@SheetmetalHVAC__ I did not say you equipment is not correct. I said the cuts are bad for someone who does this on a daily basis.

@@kirilkirov6036 put your volume up you may have missed the part that I said I’m doing this real quick and the cuts are not strait or perfect. The point of the video is to show different ways that you can cut sheetmetal. Also even if it wasn’t perfect slap some duct seal on it and it’s all set.

I’ll have to try that! I need new blades on my double cutter

The connection is a large end and small end all slip connection so it was already notched on one side. The less notches I need the less air leaking I have to deal with. On this project it had to be all aeroseal so everything has to be as tight as possible
