New burners are made to use fresh air intakes for combustion. *You can
buy a vent made for that purpose and either run dryer vent or PVC pipe

Ours is 2" PVC pipe, as per the furnace manual (when I think of dryer
vent I think of 4" stuff, which might be overkill if the furnace doesn't
need it)

Oh, our home depot has a Kidde smoke alarm + CO alarm package at $26 at
the moment - not sure if it's a national offer. The CO alarm runs from AC
with battery backup, which is nice (although it won't take a rechargeable
battery and charge it)

A furnace with a 2" PVC vent works because it has a draft inducer to
pull the air
through the pipe and vent the exhaust back out. If the OP has a
furnace that works
with a traditional chimney, that size pipe isn't going to move enough
air to amount
to anything.
