I have a Regency stove with 6" outlet. I`m wondering if this 6" to 8" adapter would be okay to use where pipe goes through the ceiling as the Stove came with 8" Triple-wall SS? Also, will the unit draft okay with this 6" to 8" expansion?

Our Answer:

The general rule for increasing stove-pipe diameter is "yes, if it's old". Older model wood stoves were not manufactured to the strict efficiency standards that new stoves are today. So, older stoves send a lot of heat up through their flue pipe. Because of this inefficiency, older stoves can tolerate an increase in flue diameter. Please keep in mind that it's always a good idea to make this change over as far from the flue outlet as possible. Thereby taking advantage of the narrower flue pipe to establish a strong draft. It's hard to say whether or not this increaser will mate to your triple wall chimney pipe. Since this unit offers a crimp end, you may be able to negotiate it into your existing pipe. It's always hard to mix brands of venting pipe - there are no guarantees.
