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 103HT (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.
