How to vent a wood burning stovepipe through a wall

Updated February 21, 2017

A wood burning stove can be vented through a wall if triple-wall insulated pipe is used. Stainless Steel Class A Insulated Chimney pipe is the only stove pipe manufactured to allow combustible materials to pass through.

The wood burning stove needs 45 cm (18 inches) of clearance between it and anything that could catch on fire. Using triple-wall pipe reduces the clearance needed by 50 per cent. When installed correctly, a wood burning stove will safely heat a home for many years.

Place the insulated chimney pipe on a piece of cardboard. Draw around the circumference of the chimney pipe to make a cardboard template. Enlarge the diagram by adding 10 cm (4 inches) to the circumference. Adding 10 cm (4 inches) to the diagram allows for 20 cm (8 inches) of total clearance. Cut out the cardboard template with a pair of scissors.

Use a stud finder to find hidden wall studs under the wall surface. Slide the instrument from side-to-side until it signals a stud has been found. Place your template between wall studs. Walls built on 60 cm (24 inch) centres will provide an adequate amount of clearance.

Locate the wood burning stove to minimise the risk of uncovering electrical and plumbing lines. Wood burning stoves should be 60 cm (24 inches) from an electrical socket or switch plate.

Tape the chimney pipe template on the wall in alignment with the appliance flue collar. Draw a line around the template to use as a cutting guide.

Cut around the guide lines with a utility knife or hand saw to remove the wall sheathing. Cut and remove the wall insulation. If electric or water lines are revealed, call a local contractor to relocate them.

Drill a pilot hole in the centre of the exhaust hole through the perimeter wall sheathing to the outside. Align the template on the outside of the home with the pilot hole. Consider calling a contractor to remove the exterior siding of brick homes.

Cut through the siding from the pilot hole to the outer edges of the guide lines using a reciprocating saw. Remove small pieces at a time until you can easily steer the cutting blade. Change the blade according to the siding material. Saw blades are made for aluminium vinyl and wood.

Pass the chimney pipe through the cut hole from the outside of the house. The male crinkled end should pass through the hole first.

Slide a piece of appropriately sized vent pipe flashing over the chimney on the inside and outside of the home. Do not secure this pipe until after all stove pipe is aligned and installed.

Insert the insulated chimney pipe into the flue collar on the wood burning stove. Screw three 1.2 cm (1/2 inch) screws at the joint to attach the pipe to the stove. Three screws are the minimum requirement at each joint.

Attach the remaining flue pipes to the insulated chimney pipe extending above the roof line by 90 cm (3 feet).

Place anchor lines per the manufacturer's instructions. Anchor lines are recommended to keep the pipe from moving in high wind.


Cover all combustible surfaces with noncombustible material. Apply for any permits needed to install a wood burning stove in your area.


Never use galvanised pipe as it will off-gas in a home. Galvanised pipe that is heated emits a breathable toxic chemical.
