Gas Furnace venting

I am in the middle of a remodel in seattle and have a six 6 diameter exhaust vent for my furnace that currently runs up through the roof. My question is can I re-route the vent through the floor to vent out the side of the house instead of through the roof?

Gas Furnace venting

Being six inch I have to assume you mean a metal chimney. No you can't vent out the side with out a specialized motor driven fan system


Just slow, not stupid.

Gas Furnace venting

You could do this, if you absolutely must, but you would need a double wall galvanised vent pipe and an exterior power venter. Unless you positively, absolutely, must go this direction, I would avoid it as the external power venters are expensive and unreliable.
