DuraVent DVL Close Clearance Connector Kit: pipe for a straight run to an 8 foot ceiling
The DuraVent DVL Close Clearance Connector Kit is a 6 inch pipe kit for a wood stove that vents straight up to the chimney. It brings together the pipe pieces for a typical room with an 8 foot ceiling and a DuraTech or DuraPlus chimney. You get an adapter for the top, two straight lengths measuring 24 inches each, and a 12 inch adjustable section to bridge the remaining gap. DVL is DuraVent’s double wall black stovepipe, the pipe that runs from a wood stove to the chimney inside the room. The chimney, ceiling support box, and connector at the stove outlet are sold separately.
Air between the two walls provides insulation. DVL needs 6 inches of space from a wall and 8 inches from a ceiling, rather than the 18 inches single wall pipe requires. That gives you room to place the stove closer to the wall. DVL cannot be cut. The adjustable section slides over a straight piece to fit the space left over. Have a taller ceiling? Add DuraVent DVL Double Wall Black Pipe straight lengths. The DuraVent DVL Close Clearance Connector Kit ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

FAQ
What is in the DVL Close Clearance Connector Kit?
The 6DVL-KVP kit contains a DVL Adapter, two 24-inch lengths of 6-inch DVL double-wall black pipe and one 12-inch DVL adjustable length. Together they run from the stove collar to the chimney support box in a typical 8-foot through-the-ceiling installation, with the adjustable section absorbing the final few inches so no pipe has to be cut.
Why choose DVL over single-wall stovepipe?
Clearance and draft. DVL’s air-insulated double wall is listed for 6 inches to walls and 8 inches to ceilings, against 18 inches for single-wall pipe, so the stove can sit much closer to the wall. Its stainless inner wall heats up faster and stays hotter, which strengthens draft and reduces creosote. DVL is also required for solid-fuel stoves in manufactured homes.
Can the pipe be cut to length?
No; the instructions say DVL cannot be cut. Length is adjusted with the 12-inch adjustable section in this kit, which slides over a straight length and is screwed to lock it. Each DVL joint takes up 1-1/2 inches. If you need more reach, add straight DVL lengths; longer adjustable sections and adjustable elbows are also available.
How does the connector pipe attach to the stove and to the chimney?
At the stove, if the inner sleeve fits the collar no adapter is needed; if it nearly fits, crimp the sleeve; if the collar is too small, use the DVL Adapter that comes in the kit. At the top, DVL locks straight into a DuraTech support box, while DuraPlus needs the DVL/DuraBlack Chimney Adapter with Trim, which the DuraPlus kits include. Rear-exit stoves should use a tee rather than a 90-degree elbow.
Can double-wall connector pipe pass through a wall or ceiling, or be enclosed?
No. Like all connector pipe, DVL may not be enclosed and may not pass through walls, ceilings, attics or closets; it ends at the chimney’s support box or wall thimble. Keep the run as short and straight as possible, do not mix it with single-wall pipe, and give every wood-burning appliance its own connector and chimney.
Do the joints need screws, and is smoke on the first fire normal?
Fasten each connection with three screws (#8 x 3/8 inch) into the outer wall; DVL does not use joint sealant. Expect a moderate paint-like odor and light smoke during the first few fires as the black finish cures; it clears after a few uses. Inspect the connector and chimney monthly during the heating season and clean when creosote or soot has built up.
