CHIMNEY SIZING
stove. If the chimney diameter is too large, it will be dif-
ficult to raise the chimney flue temperature to provide for
adequate draft. This may result in a poor burn, smoke
spillage, and rapid creosote creation. A 6” diameter
chimney is best suited for this stove.
Your heating appliance must have a minimum of
a 6” diameter (152mm) chimney. Maximum chimney
diameter must not exceed 10” (254mm) or have a cross
sectional area greater than 85 sq. in. (550cm
2
.)
Proper draft for this heating appliance is minimum of
0.05 w.c. (water column measurement) and is required
to prevent back puffing, smoke spillage and prevent
safety hazards.
Today’s solid fuel heating appliances are much
more efficient than those made in the past. Your heat-
ing appliance has been designed to provide the most
efficient transfer of heat possible from the least amount
of fuel.
Controlled combustion is the key to optimum heat-
ing performance. Controlled combustion requires a flow
of fresh air into the appliance, across the fuel and is
finally exhausted up the chimney.
Today’s high efficiency stoves transfer more heat
into the living area and less up the chimney. Exhaust
gases are typically at a lower temperature than tradi-
tional type stoves. With lower exhaust temperatures, it
is important that the chimney is correctly sized to the
CHIMNEY CONNECTIONS
The stove must be connected to either a lined
masonry 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 ap-
pliance, 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
burning appliances and the possible development
of hazardous conditions, fire or death.
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
detailed in figures 11–13.
If these minimum require-
ments 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.

IMPORTANT Installation Points
1. Size chimney flue to stove collar. This stove
requires a minimum of a 6” 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
Fig. 10 - Masonry Chimney Connection
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 10.
If the connector stove pipe must go through a
combustible wall before entering the masonry chimney,
consult a qualified mason or chimney dealer. The instal-
