Finished garage furnace install - Thanks to all that helped!

[Scott R]

I was able to fire up my new garage furnace today, and it's great! Thanks mb911 for the suggestion that I get a 45,000 BTU hanging furnace, it works perfectly!

The furnace in the picture is an Armstrong CGHA series 45000 BTU side exhaust furnace. I purchased the furnace slightly used on Ebay for $350. The big cost was the gas line install, that ran me $700 for 40ft and two shut offs. The electrical would have been another $200 if my best friend was not an electrician.

Again thanks to all that posted, excuse the mess in the photo, now that it's warm in there I'll start on cleaning it up.

Right after the insulation, I'm waiting on a friends kitchen demolition.

Looks good! Now go get a smoke/carbon monoxide detector, wire that in and you're up to code.

Regards,

Edit: that's an awfully long lateral flue - can you go up through the roof? It would draft better.

Sorry to burst in here.... I am a state licensed HVAC business owner and I couldn't help but notice your installation. Your furnace venting concerns me. If you do not have an appropriate rise in the vent (1/4" per foot) you need a power venter wired into the furnace for that horizontal run. It should be closest to the outside wall where the flue exits. From what I can see, with no rise or power venter, you will overheat the furnace's heat exchanger and eventually crack it. This leads to carbon monoxide poisoning which eventually leads to death. Sorry, just looking out for you. Bob

The unit does have a power vent, it's an Armstrong CGHA series, it was inspected the other day and was found to be to code, and installed per the vendors guidelines. My inspector had the same initial concern before we cracked the side cover so he could view the exhaust blower.

This system fires the exhaust blower first, then the heat exchangers, then the actual blower. The uint is controlled by a complex integrated circuit board that actually ****s down in the event that venting is not correct. On top of that I have affixed a digital CO meter in the garage for added piece of mind.

I chose this unit so I did not have to adjust for rise, I wanted a cleaner, easier installation.

Here is a link to the furnace specs:

I see in the manufacturer's specs it includes a power venter for horizontal ducting of the flue. That's great. As you can imagine, I couldn't see inside the furnace from your picture. In my field, I normally see at least one job per month that is a raging fire hazard and/or death trap waiting to happen. I'm glad yours is not one of them! Now go enjoy your warm garage!

I have a similar system, made by Modine. I did all the work myself, and it's been a charm. Love the warmth! You'll wonder why you didn't do it sooner!

Thanks! And thanks for the concern, this was my first install and I was very worried that I would somehow burn my house down. I tried to follow every step in the book verbatim, and every local code I could find.

The nice part is all of my machine work is done, and now that I have heat I can start my rebuild.

Nice work. Now you need shelves, pegboards, more lighting, workbenches, and a 2-post lift.

Almost there!

Check!

I have the benches, it's a three car garage, the picture does not do it justice.
