Harman Wood-Burning Stove Pipe Installation

Obtain stove pipe sections sized to fit your stove's flue collar. Review accompanying manufacturer guidelines for approved types of pipes. Check local building codes for any modifications you may need to make to your layout and pipe clearances before beginning the installation.

Attach stove pipe sections to the flue collar of the stove with the crimped ends facing the stove and a slight overlap at each joint. Secure with metal screws. Avoid using more than two 90-degree bends in the piping.

Determine the best layout for connecting to your chimney. Harman wood stoves, like many solid fuel stoves, require a masonry or metal chimney kit for venting. You can send the stove piping through a wall to connect to a masonry chimney or run the piping up the exterior of the house to a metal chimney on the roof. Another option is to cut a hole in the ceiling to connect to a rooftop chimney.

Examine your chimney to ensure it is in sound condition. If your chimney does not have a liner or is not approved for wood-burning stoves, you will need to install an Underwriter's Laboratory-approved liner that is manufactured for such heating devices.

Maintain proper wall clearances if you are passing the stove pipe through a noncombustible wall to reach a masonry chimney. Clear 12 inches around the chimney pipe connector. Install brick masonry by applying mortar and bricks, leaving a space for the pipe's passage. Install a fireclay thimble, using refractory cement and following manufacturer instructions, to line the area from the brick wall to the chimney liner. Direct the pipe into the thimble until it reaches the edge of the chimney liner.

Acquire necessary materials for running the pipe through a ceiling, if necessary. You will need a ceiling support box, chimney adapter and chimney kit. You may also need an attic insulation shield. Install the chimney kit according to the product's manufacturer. Cut a hole above the stove and install a ceiling support box as directed. Extend the chimney pipe down through the support box to about 4 inches down, and connect to the stove pipe with a chimney adapter. Secure all pipe sections with metal screws or as directed. Install an attic insulation shield if running the pipe through an attic.
