GBlist: replacing old natural gas furnaces

[Splat Ski <splatski@proaxis.com>]

We're replacing an old central heating furnace.  Existing furnace is in our
garage (an attached garage).   
Please share advice regarding the best approach, for indoor air quality.
We also have a gas "fireplace" on an exterior wall, which I want to switch
to a wood-burning unit.  Can I simply remove the fake logs, cap off the gas
pipe, and start burning wood?  Current unit has gas pilot going year-round.
Thanks.
