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 t
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
diameter chimney flue system. The conne
(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.
