    *Venting Requirements: This unit requires venting pipe with an inner diameter of 6 Inches. Please see the Venting Components section on this page for venting pipe that must be used with this unit.

    Vent installations each have their own unique style and needs, which is why Selkirk provides this adaptor that helps make ventillating your chimney much easier. With this connector, you can connect your stovepipe through a chimney wall with as little as 6 inches of clearance. This accessory is available both in 6 and 8 inches in order to accommodate your ventillation needs, and the scratch resistant black color allows it to blend in with most vent systems.

    from Edinboro, PA asked:
    May 3, 2017
    I found that single wall pipe fits extremely loose. Is there some transition adapter available for this use? My application requires that an elbow be incorporated very close to this masonry adapter. Any suggestions other than securing single wall pipe with screws?
    1 Answer
    The reason this adapter does not provide a secure fit is because this part should only be used with Selkirk DSP double wall stovepipe of the same diameter. This stovepipe may be viewed by selecting your diameter and Selkirk from the filters along the left-hand side of the page in this product category.

    I was wondering, can this adapter can be used to connect a double wall stove pipe to a masonry chimney that has a clay liner?
    1 Answer
    Masonry adaptors like the product in question are intended to be used to connect listed double wall pipe to a masonry chimney that has been relined with flexible stainless chimney liner of the same manufacturer as the double wall stovepipe.

    Whats the difference in using this Selkirk DSP double-wall black stovepipe masonry adaptor vs a wall thimble?
    1 Answer
    This part essentially takes the place of a thimble in a masonry application. The part is not insulated for use through a combustible wall however.

    from Billerica, MA asked:
    October 30, 2015
    I have a 6" pipe wood stove and a "square" clay thimble. The inside dimensions are 6-3/4" x 7". The builder must of used the same clay liner for the chimney and used a leftover piece for the thimble in the 1960's. Would it meet code standards to use this double wall stovepipe through the square thimble. I assume the outside diameter is less than 6-3/4"? What would I do with the space in between the pipe and the square thimble?
    1 Answer
    While we will be able to provide guidance that will meet NFPA 211 standard, this standard is only accepted as code if it is adopted by your local code enforcement agency. However, using the Copperfield Galvanized Stovepipe Masonry Chimney Thimble - 6-Inch Diameter along with Rutland Pre-Mixed Chimney Sweep High-Temp Furnace Cement - 16 Ounce Tub to close the remaining gap should be sufficient.

    I just purchased the Selkirk DSP double-wall black stovepipe masonry adapter. Does there need to be a ceramic wool between this and the clay thimble? Is there another type of wool that can be used?
    1 Answer
    The DSP masonry adapter is designed to be used without insulation between the outer wall and the clay thimble, however if there is additional space that needs to be taken up or if you would like to insulate better, standard fiberglass insulation with no paper facing can be packed between the two.

    from Ardmore, TN asked:
    December 22, 2014
    I have a masonry chimney with a 6 inch ceramic thimble that has broken. The broken thimble is 6 inches x 18 inches. Can I use this product to replace the ceramic thimble or do I really need to replace the broken thimble with another ceramic thimble? I plan to use 24 gauge single wall stove pipe. Once the new thimble is in place.
    1 Answer
    This product is made specifically to pass the DSP double wall stovepipe system into a masonry chimney. As such, you would not be able to use a single wall system if this is installed. If the chimney is fully masonry with no combustible framing, a product such as the Copperfield Galvanized Stovepipe Masonry Chimney Thimble - 6-Inch Diameter could be used. The product is only 12 inches long, so a pair of them would need to be used for your application, with the second being cut down to 6 inches.

    I need this item, but I also need a 8" x 6" reducer because my stove is 8" but the vent hole is 6". Do you carry this product?
    1 Answer
    We do indeed carry the 8" to 6" reducer that matches with the Selkirk DSP masonry adapter. Please view this reducer here.

    from Maine asked:
    September 22, 2014
    I'd like to use this product to pass through a brick faced wall into a masonry chimney behind the wall. I have two questions: 1. the pipe from my stove is 26 ga single wall, will that connect to the front of this adapter? 2. the distance from the brick wall to the chimney is 15 inches, can I extend the back of this adapter with DSP to make up the 4 inches I'm short?
    1 Answer
    This adapter can indeed be connected to 22-26 gauge single wall pipe, although the air space between the inner and outer walls on the adapter will be exposed. Unfortunately, DSP does not connect to the back side of the adapter to extend it any further.

    I have a masonry flue that has a clay connector pipe coming through a block wall. What can I use to connect to the masonry flue and safely come through the wall and connect to my wood burning stove?
    1 Answer
    The DSP adaptor you are viewing now is intended specifically for this purpose. The adaptor is designed to pass through a clay thimble into a properly lined masonry chimney. You can then connect DSP double wall stove piping between the stove and the adaptor. Keep in mind that the even with the adaptor, a 6 inch apron of noncombustible material must encircle the pipe as it passes through the thimble. Cement board can be used for this purpose.

    I have a terracotta thimble in a masonry fireplace. The thimble is 21.5" long. Am I okay with the adapter only being 12" long and not the whole way through the thimble?
    1 Answer
    As long as the terracotta thimble is in good condition for the entire length, it will not be an issue for the adapter to terminate short of the end of the thimble. It is recommended to seal around the adapter on the inside of the home with furnace cement to prevent smoke backpuffing.

    Do you use furnace cement to secure this? Is the attached collar is in the way when applying the furnace cement?
    1 Answer
    Indeed, furnace cement is suitable for this application. To install, the adapter would be placed partly into the hole prepared in the clay pipe (leaving room to work behind the collar). A bead of cement would be applied onto the adapter just behind the collar. When the collar is pressed fully into the clay pipe, the cement will seal the gap between the adapter and the clay.

    Can you attach a 6 " double wall stove pipe directly to this adaptor?
    1 Answer
    Yes. In fact, that is its prime objective. It is part of the Selkirk DSP Double-Wall line.

    I would recommend this item to a friend.
    I was very pleased w/ this pipe adapter. i didn't want to make my entire pipe double wall b/c of heat loss and cost so i got this adapter to fit inside of my chimney thimble and was able to connect the single wall corner directly into it. have been burning a fire for weeks now and no problems; often feel around it and the other wall protection and find nothing warm to the touch!

    Prosdouble wall stove pipe stays remarkably cool on the outer surface.
