I just installed a furnace in the garage/shop and the guys that put it in said go with a 3' vertical vent through the roof, but the manual says 5'.
The problem with a 5' flue is that I have a hip roof with a low pitch, so a 5' flue sticks up above the roof about 4', catching wind and really getting moved around. I really don't want to brace it to the roof, looks terrible.
How many of you have used a 3' flue and do not get condensation problems because of the length, etc.? The horizontal pipe is only about 2' long on the inside of the garage.
