Again, this is a down flow furnace out of a mobile home. Just noticed it says "Sealed Combustion" and my insurance company said it's OK for me to use it in my garage. Down flow, so I'll weld a stand for it to sit up off the floor about 8".
Question about flue exhaust and fresh air inlet. This is an 80% unit (I'm guessing 57K BTU's out divided by 70K BTU's in = 81%? )
Can this be used with the flue exhaust/air intake being terminated on an outside wall similar to 90% units but metal, not PVC? Or must this flue go a certain number of feet higher than the roof? Or something in between the two?

Best bet. Contact the manufacturer to get a copy of the installation manual for that furnace.

What does your building code require? A code compliant installation will make your insurance company happy.

I forgot to mention there is _NO_ building code where I live. We have septic and electrical codes/inspection but no building code.

Normally mobile home means "direct vent" with sealed combustion. This means a specialized vertical vent termination would be the only one you could use. I see manuals you can "buy" online; such as this one;
You may have to call or e-mail, but I'm not sure they will help an individual for retail sale, as they are wholesale suppliers to the mobile home industry.
If you are going to have to wing-it all alone, you may want to try a gas fireplace vent kit and termination. But that may be quite risky, both for safety and functionality.

When I had something similar in my trailer (80 percenter) the flue gas went up through the roof, and then six inches or so more. Thre was assembly up there to keep the rain out.
I'd suggest a similar set up. I used indoor air for the combustion. There was a bit of a hole in the floor, so it drew air from under the trailer for the combustion.
Of course, the manufacturer is a good idea. But, it sounds reasonable. Flue gasses too hot for PVC. Needs metal, but you wrote that below.

Only problem is that it will be going 16' straight up, most of it through the unfinished attic and then not sure how far above the roof. And I hate putting holes in my new steel roof!

Dang, for $15 I'd be happy to buy a manual, but mine isn't offered. Figures.
I forgot to mention before that there is a blower for the combustion air. It's before the combustion, not sure if that is still called a "power vent" or not. Either way, with the blower it's not as if it needs to rely on a great natural draft.
