I have a Carrier 8000 mid efficiency gas furnace and it is working fine, replaced the blower motor couple of months ago and I would like to keep it for a now. The problem I have, it burns the oxygen from the basement for combustion and the basement is a living space. Because of this I have to open basement windows every day which results in heat loss.

I want to modify it to bring air from outside for combustion, similar with the high efficiency ones. The idea is simple, bring a PVC pipe from outside into the furnace and cover the openings in the front panel (grille) so the air is drown from outside instead of the basement. Would that be a violation of any safety rules? The furnace is 7 years old, no longer under warranty.

The Carrier 8000 does have an inducer motor. Isn't that used for "assisted" venting? If the inducer motor pushes the air out, it must help draw air in as well. Am I wrong in my assumption?
