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?
