Newer building codes require a separate air supply for gas stoves as well as venting outside.
With a high efficiency furnace the combustion air comes from outside and is directly vented outside.
That leaves water heaters which are vented either up the chimney (mostly these days with a liner) or a forced air vent.
A mid or low efficiency furnace vented to a chimney without a liner could well result in combustion products leaking through the chimney into the house.
Heat exchanger leaks could also be a factor, but usually the duct space is higher pressure than the vent which has the chimney draft. Leakage can still happen before the draft develops after ignition.
- Schiendelman 5y agoThe newest building codes (in New York, Seattle, and a few other places) simply ban gas hookups. You don't want that NO2 outside in a dense city, either.

- throwawaysea 5y agoCan confirm. I have a high efficiency furnace and gas stove and both vent outside. I also have air quality monitors and filters and cooking does not set them off, so I feel like the claims about indoor pollution are overblown and just being used to try and justify banning gas stoves.
