Hi all

we recently removed our oil burning furnace from the basement and put a new unit in the attic. We are looking to heat the basement with a wood stove. Can we vent the wood stove out the old furnace chimney with a few feet of pipe going up? Or do we have to line it the whole way up with pipe? Again, this is an old furnace chimney that not in use anymore. Thanks in advance
 
If everything is right, possibly. The chimney would need to be cleaned and checked for integrity. It needs to be sized to the stove requirements. Typically that is a 6" flue outlet. If the chimney has an 8x8 tile liner then it may work. The next thing is whether the chimney was built to code. It should have 2" clearance from all combustibles all the way up. This is not too common, but sometimes they do it right. FWIW, we actually had a furnace chimney that was properly done to code. It was put in long after the house was built during a 1984 remodel.
