Optima Installation and Operation Manual

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.
