8 The Venting System

8.1 General

The venting system, made up of the chimney and the connecting pipe between the stove
and the chimney, acts as the engine that drives your wood heating system. Even the best
stove will not function safely and efficiently as intended if it is not connected to a suitable
chimney.
The heat in the flue gases that pass from the stove and chimney connector into the
chimney is not waste heat. This heat is what the chimney uses to make the draft that
draws in combustion air, keeps smoke inside the stove and safely vents exhaust to
outside. You can think of heat in the flue gas as the fuel the chimney uses to make draft.

8.2 Suitable Chimneys

Your wood stove will provide optimum efficiency and performance when connected to a 6-
inch diameter chimney flue system. The connection to a chimney having a diameter of at
least 5 inches (Canada only) or no more than 7 inches is permitted, if it allows the proper
venting of combustion gases and that such application is verified and authorized by a
qualified installer. Otherwise, the diameter of the flue should be 6 inches.
To be suitable, a factory-built metal
chimney must comply with UL 103 HT
(U.S.A.) or ULC S629 (Canada).

8.2.1 Factory-built Metal Chimneys

These are sometimes referred to as 'high
temp' chimneys because they have the
special characteristics to withstand the
temperatures that can be created by
wood burning stoves. Factory-built
chimneys are tested as a system with all
the necessary components for
installation. The instructions provided
with the chimney by its manufacturer are
the only reliable source of installation
guidelines. To be safe and effective, the
chimney must be installed exactly in
accordance with the manufacturer's
instructions. Use only components
intended for the brand and model of
chimney you are using. Never
substitute parts from other chimney
brands or fabricate your own
components. The chimney must be a
type suitable for solid fuel.
