Looking for HVAC advice

[Cableguy]

Do we have any HVAC techs on this board. I'm trying to install a Gas, forced air heater in garage and have a venting question.

I know enough to be dangerous, what is your question

[Crawdaddy]

ditto...I have a few relatives and friends that are HVAC techs...

Ok cool, the furnace I put in is 45000BTU gas heater in garage...

Installed 3" elbow to 3" x 36" B-vent, passes thru ceiling with a timble...

Where it passes thru roof, can the B-vent touch roof or does it need 1" clearance all the way around? before I put on vent cap and storm collar.

I believe you need an inch clearance around the B-vent. Also make sure the boot for the roof flashing is metal as well. Let me know if you have any other questions, I will try to anwser as best as I can.

[Cableguy]

Thanks. That roof flashing is metal and the B-vent is touching time to get up there with the sawsall again. Damn. Maybe I should just stick to fixing Cable TV.

Still waiting for my pipe fitter to hook up gas to furnace and to my gas meter. I need heat already...water was frozen in the back of my P/U over nite, BRRRRRR.

[Crawdaddy]

you're from the great freezing-*ass col north... That shouldn't be an issue for you :glasses:

I was wondering if you looked and reviewed the Heat/Pump units. I'm thinking to do the combination, it's either too cold or too Hot in Maryland. The other is installing a Wood Pelt stove. Yeah, I know it all about COST ttoo. Please share your cost factors to completion.

[Cableguy]

So far I'm $599 for heater, $100 for B-vent kit, $600 to install gas main from house to garage/workshop (Approx. 60' bore, 1" plastic, 2 shut offs)(Done by gas contractor) Now I need a friggin' pipe fitter if he'd ever bother to get his @ss in gear. It's going down to -2 tonite. BRRRRRR

[guillaume]

Which model did you go for you room space. I have a monster garage and I'm wondering if 75,000 BTU would be enough, 30ft x 60ft. As I'm posting this, my son and his buddies are putting more insulation. I have a pole building, wood and aluminum, so we're doing the fiberglass insulation over 3/4 plywood.:glasses:

[Cableguy]

Thanks for all your advice fellas.:great: I'm all done, installed and inspected. I have HEAT baby! Like you would not beleive in my workshop, 45000 BTU's of pure heaven ....

I was so happy I started to build my wife a pub/cafe table for my basement bar area. Lots of sanding to do, stain it, then I think I'll go with bigger bar stools than the one in picture.
