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 (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.
