CHIMNEY SIZING
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
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˝/152mm di-
ameter chimney is best suited for this stove.
Your heating appliance must have a minimum of
a 6˝/152mm diameter chimney. Maximum chimney
diameter must not exceed 10˝/254mm or have a cross
sectional area greater than 85 sq. in. /550cm

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.

Fig.15 - Masonry Chimney Connection
The stove must be connected to either a 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 combus-
tion.
2). The chimney provides a natural “draft” which
allows oxygen to be continuously introduced into
the appliance, so that proper combustion is
possible. Insufficient draft will not allow this
stove operate properly.
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 chim-
ney must meet the four minimum height requirements
detailed in figures 16 – 18.
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
contractor for assistance in solving the problem.
IMPORTANT Installation Points
1. Size chimney flue to stove collar. This stove requires
a 6˝/152mm diameter flue. (see Chimney Sizing)
2. Never connect this unit to a chimney serving
another appliance.
3. The chimney must meet all minimum height require-
ments.
4. Never use a chimney to ventilate a cellar or base-
ment.
5. C o n t a c t y o u r l o c a l b u i l d i n g a u t h o r i t y
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 con-
nector stove pipe and fittings you will need to con-
nect directly to a masonry chimney are shown in
figure 15.
