Place your freestanding woodstove the recommended distance from the wall in the area of the house where you will be installing the fireplace. Follow the manufacturer's instructions regarding the actual distance required, as each type of stove on the market has different requirements. Maneuver the stove into a position that requires as few bends in the stove pipe as possible in order to allow the smoke the easiest route out of the house.
Fit a piece of Selkirk pipe over the exit pipe on the back of the stove to direct the smoke from the stove into the chimney (or in the case of insulated double-walled pipe, to act as the actual chimney itself). Place the crimped, male end of the joint inside of the uncrimped female sections of the pipe, always ensuring that the male end is facing downwards so the smoke is always forced to rise. Secure the sections of pipe together by using self-tapping metal screws and drill, with at least three screws to every section of joined pipe.
Add one section of pipe at a time, always slotting the crimped male end into the smooth female end. Work your way up the wall from the bottom up, or simply run the Selkirk pipe from the stove to the chimney in cases where an existing chimney is already in place. Ensure that the stove pipe rises at least three feet beyond the roof with the finished pieces.
