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?

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.

Will this still of reducer adapt to snap lock pipe?

This particular adapter is intended to adjust the I.D. of Selkirk DSP stovepipe. Given that the DSP line is a double walled product, this adapter cannot be used with snap-lock stovepipe.
However, we do carry a couple of single wall adapters that can work with the snap-lock type stovepipe. The 8" to 6" Reducer
and 8" to 6" Increaser
may suit your needs.

I currently took down our old fireplace as it was totally broken. The chimney pipe that the fireplace had was an 8" triple wall stainless steel pipe. We now want to buy a wood stove and connect the stove to this existing pipe but the stove is a 6" flue. Can this be done? Do I have to take down the entire existing chimney pipe and run a new one or is there an adapter that will fit from a 6" flue to a 8" triple wall stainless steel pipe?

Answer:Unfortunately, the Class A chimney that is used with a wood burning fireplace and the Class A chimney used with a wood stove is very different. Components are generally not interchangeable. As such, you will need to remove the existing chimney system and replace it with a new 6 inch Class A chimney.
