How to Install a Double-Wall Stainless Steel Heat Pipe

Preparation

• Before installing a double-wall stainless steel heat pipe, measure the space around your stove. If the heat pipe won't come within 18 inches of any wall or combustible surface, you have the option of selecting a single wall heat pipe. However, in tight spaces or if you're concerned about the risk of fire, select a double wall stainless steel heat pipe that is the length of the distance from the top of your stove to the 90-degree chimney elbow that enters the room above it.

Fitting

• Fit the heat pipe into place with the crimped end closest to the stove. Push this end gently into the larger heat pipe adapter that is attached to the top of the stove. Hold the heat pipe in place while inserting the crimped end of the chimney elbow into its open top. If the heat pipe won't reach, or if there is insufficient overlap for it to stay in place, you'll need a longer pipe or a different adapter.

Sealing

• Once the heat pipe is in place, insert metal screws into the predrilled holes that align with holes in the chimney elbow and stove adapter. If these holes don't yet exist, drill them with an electric drill and metal bit. Some double-wall stainless steel heat pipes have holes large enough to accept rivets, which take the place of screws. Once the rivets or screws are in place, apply furnace cement to the joints.

Finishing

• Most double-wall heat pipes are painted black to match indoor stoves and avoid showing the soot and debris that accumulate during use. A stainless steel pipe may require occasional cleaning to maintain its shine and clean, modern look. Wipe the heat pipe with a clean cotton cloth and warm water once the furnace cement has dried. If the pipe becomes dirty in the future, use mild soap or a specialty stainless steel cleaning solution.
