How to Hook a Stove Pipe to Wood Burning Stove

Save

While your wood burning stove can be a romantic focal point on a winter's Eve, it also performs a vital function in heating your living area. Proper installation of the stove is critical to both its immediate use and its long-term efficiency. By correctly connecting the stove pipe the first time, you can preclude excessive smoking and ensure the firebox has good airflow for optimum performance in days to come.

Things You'll Need

  • Wood stove
  • Stove pipe
  • Measuring tape
  • Bar of soap
  • Tin snips
  • Stove pipe cement
  • Sheet metal screws
  • Power screwdriver

Prepare

  • Decide how you will vent your wood stove. Depending on the location in the room and the height of the ceiling, you will have the option to: 1. Vent vertically through the ceiling and roof; 2. Vent vertically through the ceiling and attic with the addition of an attic kit and roof support kit; 3. Vent vertically to a pipe elbow, then horizontally through an outside wall .

  • Position the wood stove in its permanent location. If you are venting straight up through the ceiling/roof, the stove's pipe opening should be positioned directly below the roof opening. For a vertical/horizontal through the wall installation, the stove should be positioned far enough away from the wall to both meet recommended clearance standards and allow for a horizontal run of pipe from the elbow. According to Hearth.com, "a single wall chimney connector often has a clearance of 18 inches from combustible walls" . Reduce this clearance, if necessary, by using a heat shield on the wall behind your wood stove.

  • Prepare your stove pipe. For a vertical venting installation, you will need enough length to reach the ceiling support assembly. For a vertical/horizontal set-up, you will need at least two pieces of straight pipe plus an elbow.

Install the Pipe

  • Measure the length of your first pipe section. If cutting is necessary, mark your cutting line with the edge of a bar of soap. Use tin snips with angled handles for easy access to the round pipe. Open the pipe up slightly by disengaging the seam connection. Do not worry; you can easily reengage the seam when you are finished cutting the metal.

  • Fit the first section of pipe into the wood stove opening. Slide the pipe into the stove until it is firmly seated. Rub with soap to ease fitting, if necessary.

  • If you are using an elbow, fit this inside first pipe section. Check to see that the elbow opening in now lined up correctly with the wall opening.

  • Slip your next pipe section into the elbow. Ensure that the pipe is the precise length you need to pass through your heat shield or other wall opening to the outside. Keep in mind that your stovepipe must pass through an UL-approved shield or insulating thimble and cannot pass through an unshielded wall opening.

Seal

  • Once you have confirmed that your pipe sections and connectors fit correctly, remove the sections.

  • Apply black stove pipe cement to the inside of the wood stove pipe opening, according to manufacturer's directions. Fit the first section of stove pipe back into the opening.

  • Continue applying cement sealant as you reassemble your stove pipe connections. Remove any excess cement with a wet cloth as you work.

  • Allow cement to dry for at least 24 hours.

  • Using a power screwdriver, secure each pipe connection with 3 sheet metal screws .

Tips & Warnings

  • Try wetting the surface area of the stove pipe prior to applying cement sealant to aid adhesion.
  • Improperly installed stove pipe can present a fire hazard. Always abide by manufacturer's specifications and UL regulations when selecting and installing stove pipe.
