The rules below are based on the rules found in the installation code of a solid fuel burning
appliance. It is imperative to carefully follow these installation instructions or those of the local
code.
• An ideal pipe installation is the one that goes straight from the cookstove directly into the chimney,
without elbows. A straight installation requires either a telescopic section or a coupling pipe so it
can be mounted or dismounted without having to move the cookstove. A straight pipe installation
offers the minimum amount of restriction to the exhaust of the smoke and gives a better draft.
Straight installations also need less maintenance because there are no angles where creosote can
be deposited.
• The maximum length of the horizontal pipe is 3m (10 ft.) including the elbows.
• The minimum clearance in relation to combustible materials is : 450 mm (18"). The minimum
clearance can be reduced if an appropriate heat shield is installed. See the heat shield installation
instructions for more details.
• The pipe between the cookstove and the chimney must be as short and straight as possible. It is
often better to use two 45o elbows instead of one 90o elbow.
• The maximum number of 90o elbows is two.
• The maximum unsupported horizontal length is 1m (3 ft.)
• Galvanized smoke pipes must not be used because their coating vaporizes itself at high temperature
and produces dangerous gas. Use black smoke pipes.
• Flue pipes must have a thickness of at least 24 ga.
• Flue pipe connectors must overlap at least 30 mm (1 ¼")
• Each installation connector must be fixed with at least three screws.
