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
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 all
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
chimney must comply with
(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
chimneys are tested as a system with all
the
necessary
components
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.
