CHIMNEY CONNECTIONS
The stove must be connected to either a lined ma-
sonry or manufactured metal chimney built and tested
to the specifications listed on the previous pages.
Chimneys perform two functions:
1). As a means of exhausting smoke and flue
gases which are the result of fuel combustion.
2). The chimney (only) provides “draft” which
allows oxygen to be continuously introduced
into the appliance, so that proper combustion
is possible. This stove relies on natural draft to
operate.
NOTICE: Always provide a source of fresh air into
the room where the stove is located. Failure to do
so may result in air starvation of other fuel burn-
ing appliances and the possible development of
hazardous conditions.
A stove
DOES NOT
create draft.
Draft is provided
by the chimney.
To achieve proper draft your chimney
must meet the four minimum height requirements de-
tailed in figures 9–11.
If these minimum requirements
are not met your stove will not operate properly.
A
minimum of 0.05 w.c. (measured in water column) is
required for proper drafting to prevent back puffing,
smoke spillage, and to maximize performance. (Gauges
to measure draft are readily available at stove stores
and are economical to rent or purchase.)
Factors such as wind, barometric pressure, trees,
terrain and chimney temperature can have an adverse
effect on the draft. The manufacturer cannot be held
responsible for external factors leading to less than
optimal drafting.
Should you have a problem with inadequate draft,
you should contact a licensed heating and cooling con-
tractor for assistance in solving the problem.
For a more in-depth explanation see Chimney Draft
on page 15.
IMPORTANT Installation Points
1. Size chimney flue to stove collar. This stove requires
a minimum of a 6˝/152mm diameter flue.
2. Never connect this unit to a chimney serving
another appliance.
3. The chimney must meet all minimum height
requirements.
4. Never use a chimney to ventilate a cellar or
basement.
5. Contact your local building authority for approved
methods of installation and any necessary permits
and/or inspections.
Masonry Chimney
Before using an existing masonry chimney,
clean the chimney, inspect the flue liner and make
any repairs needed to be sure it is safe to use. Make
repairs before attaching the stove. The connec-
tor stove pipe and fittings you will need to connect
directly to a lined masonry chimney are shown in
figure 8.
If the connector stove pipe must go through a
combustible wall before entering the masonry chim-
ney, consult a qualified mason or chimney dealer. The
installation must conform to local building and fire
codes and latest edition of NFPA 211 (USA) or CAN/
CSA-B365 (CDN).
If there is a clean out opening in the base of the
chimney, close it tightly.
