My stove has an 8'' pipe but my chimney has a 6''. Is it OK to reduce the 8'' right off my stove?
By eFireplaceStore on September 23, 2014
Answer:Stoves are very sensitive to being sized down by 1 inch or more. The effect is that of forcing the same volume of water through a smaller hose. Increased pressure and speed of flow results. Likewise, sizing down a stovepipe by two inches will increase the flow of flue gases, causing the stove to burn hotter and go through fuel more quickly.
If there is no way around sizing the appliance down, it should be done as late as possible. As such, I recommend using 8 inch stovepipe from the appliance to the wall or ceiling, then using the 8 to 6 inch reducer right before you adapt to the Class A chimney piping. This should help to reduce the overdraft effect.

Can this piece be used to connect a 6" flue from a FC500 to a 8" crimp 90 degree elbow flue pipe?
By Kevin E. - Fireplace Specialist on November 5, 2012
Answer:This elbow is designed to be a universal adapter. It should perform in your application perfectly well. However, some tweaking of the 6" end may be necessary to allow it to drop down inside the flue collar.

I am going from an 8" oval opening Vermont Castings stove to a 6" round Hearthstone Heritage stove. I have 12' of single wall 8" pipe which enters the box at the ceiling whic becomes 8" double wall for about 8'. Should I use the 6 to 8 inch adapter at the new stove and use existing 8" pipe (slip joint is used) or should I purchase 12' of single wall 6" pipe (including a new slip joint) and perform the 6 to 8 inch conversion at the ceiling box? My concern is for proper draw rather than expense. This is my primary heat source.

Answer:It is definitely the better idea to use 6 inch single wall piping from the stove to the ceiling and use the 6 to 8 adapter at the ceiling support box. This is especially true given your climate. The newer stoves that utilize a 6 inch collar do not release the high temperature flue gases to the chimney system that the older stoves did. As such, it is important to keep the chimney sized to 6 inches for as long as possible. The flue gases can cool too rapidly in an 8 inch chimney and loose their buoyancy, causing the stove to smoke.
