Selkirk DSP Double-Wall Black Stovepipe Stove Adaptor - For Wood Burning Stoves

Unfortunately, double wall stove pipe can not be connected to single wall stove pipe.

Selkirk DSP stovepipe has the inner liner crimped on the bottom in order to keep creosote and moisture from leaking out of the pipe. Obviously, this male end will face down. The outer wall has the crimped end facing up. This does provide the appearance of having the male end up, which is unconventional but the inner, crimped end will always direct any condensation or creosote towards the combustion chamber and always face down.

The stove adapter should be connected with the crimped end on the outer wall facing upwards.

This adapter is actually intended to connect the Selkirk DSP double walled stovepipe to a 6 inch diameter wood stove collar. Standard crimped single wall stovepipe does not require an adapter, simply pushing into the collar with a tight friction fit. Other brands that use rolled seams, such as Durablack, require a certain adapter.

The height of this adapter is approximately 4 1/2 inches tall, but the amount of the adapter that will push into the stove will vary, based on the exact diameter of the stove's flue outlet. Typically, 2 1/2 to 3 1/2 inches will be added in most applications.

These two items can indeed be used to make a rear vent connection to your chimney. The items could be used directly together or with the necessary sections of vent pipe between them.

This is indeed the correct adapter to allow you to connect the Selkirk DSP to your stove's flue outlet. Because the diameter of the flue collar and the adapter are the same, you may need to flare the outer wall of the adapter slightly to allow it to fully seat.

The height of this adapter is approximately 4 1/2 inches tall, but the amount of the adapter that will push into the stove will vary, based on the exact diameter of the stove's flue outlet. Typically, 2 1/2 to 3 1/2 inches will be added in most applications. It is often best to purchase the adapter and the associated elbow first, to test fit the installation for an exact measurement. If a damper is used in your application, it is recommended to install the damper in the end of this adapter section.

Selkirk DSP stovepipe has the inner liner crimped on the bottom in order to keep creosote and moisture from leaking out of the pipe. Obviously, this male end will face down. The outer wall has the crimped end facing up. This is done to make assembly of the piping easier, as having the male ends opposite of each other allows for the piping to slip together will less effort.

Indeed, most double wall stovepipes can have an outer diameter that is 1" or greater than the single walled variety with the same inner diameter. The safest solution would be to replace the entire stovepipe system with the double wall product, as there is not a good way to connect the double and single wall products together. Are you passing through a combustible wall, before you get to the chimney or is the chimney built into the wall? Is there a masonry thimble built into the chimney that you are venting into? Please advise at your convenience.
