The flue collar on the woodstove of a home I purchased is 8" ID, 85/8" OD. It has an 8"X6" smokepipe reducer with the 8" crimped end going into the flue collar which seems to me would allow flue gases to leak out. To contain the flue gases the reducer should fit over the OD of the collar but standard smokepipe sizes won't work. What do you suggest ?

Answer:It is actually standard practice to have the crimped male end of the stove adapter push into the inner diameter of the stove outlet. Older adapters did indeed fit over the outer lip of the collar, but leakage of creosote onto the top of the stove constituted a change in design. A stove that drafts properly will not leak smoke, as draft will follow the path of least resistance and a properly fitting collar will leave little room for escape of smoke. If the adapter does not fit tightly or smoke leakage is occurring, the adapter can be sealed with a rope gasket or furnace cement.

I have an 8 inch liner in my chimney and I would like to hook it up to a wood stove that has a 6 inch exhaust. Is it safe to use this Snap-Lock black steel stovepipe 8 inch male to 6 inch female reducer? Is it OK for a wood stove that has a 6 inch exhaust to connect to an 8 inch chimney?

It is never a good idea to vent into a larger diameter chimney for an appliance that is designed to use a 6" chimney. This will slow the velocity of flue gases as they exit the chimney system to establish draft, resulting in the buildup of creosote and performance issues with the appliance. This is especially the case with modern high efficiency stoves that are particularly sensitive to draft issues.
In addition, you would need to use an Increaser
to maintain the "male end down" connection to the stove.

I am looking at a used wood stove in excellent condition. It has an eight inch top vent. The stove I currently have has double wall 6 inch pipe all the way from the top of the stove to the top. With the new stove is there an adapter type pipe that I can put on the eight inch pipe and put in 6 inch double wall?

While it is never recommended to reduce your venting diameter from the size of your flue collar, we do have a double-wall stovepipe reducer from 8" to 6". However, it is manufacturer specific, meaning you would have to have Selkirk DSP double-wall stovepipe for this piece to work. Please see it here

Is this available in stainless?
Also I need regular crimp style .... will 'snap lock' work?
By Collin C. on November 3, 2011
Answer:This is actually a crimp type reducer, as are all of the Snap-Lock products. Unfortunately, it is not available in stainless steel. Due to a low demand for stainless stovepipe, we do not currently carry any single wall pipe with a stainless finish.
