TYPES OF CHIMNEYS
The chimney is a vital part of your stove installation. A
properly built masonry chimney or a properly installed
factory built chimney will assure a consistent draft under
a variety of weather conditions (a smoking stove is usu-
ally caused by a chimney problem). The stove flue size
is 6 (152 mm) inches diameter, which is approximately
28 square inches (711 square mm) minimum. The
maximum flue size should be no more than (3)-three
times the cross sectional area of the size of the stove
flue collar. In this case, that would be no larger than a
10-inch (254 mm) diameter stack, or approximately 85
square inches (216 square cm) maximum.
All chimneys must be installed as specified by local
building codes and according to the chimney manufac-
turer instructions (in the case of a factory built chimney).
See the chimney manufacturer instructions for exact
specifications. Factory built chimneys must comply with
UL 103HT or ULC S629.
ACCEPTABLE CONNECTOR PIPE FOR INSTALLA-
TIONS
For Standard Residential Clearances:
Six (6) inch
(152 mm) minimum, single wall, 25 gage minimum
thickness, stove pipe is acceptable. Three (3) pre-
drilled holes are provided in the flue collar for fastening
the pipe securely to the stove. Use sheet metal screws
to do this. Additional sections of single wall pipe
should be fastened together with at least three (3) sheet
metal screws each section. When connecting to the
factory built ceiling support package, use the manufac-
turer's transition piece, usually called a dripless connec-
tor, to join single wall pipe to their factory built chimney
section.
Minimum Flue Size
: The required minimum diameter
and area required for the flue size is (respectively) 6
inches / 152 mm diameter, which is approximately 28
square inches / 711 square mm. The maximum flue
size should be no more than (3) three times the cross
sectional area of the size of the 6 inches / 152 mm di-
ameter flue collar. In this case, that would be no larger
than a 10 inch (254 mm) diameter (area = approx. 85
sq. inches [216 sq. cm]).
Connection To A Factory Built Chimney
: This space
heater is to be connected to a factory-built chimney
conforming to CAN / ULC – S629, Standard for 650°C
Factory-Built Chimneys.
For Reduced Residential Clearances:
Type L and
listed double wall connector pipe is acceptable. Install
any factory built brand of pipe according to the manu-
facturer's instructions.
Vapor Barrier at Chimney Penetration
Install all venting components per the Vent Manufac-
turer’s installation instructions. Ensure that there is an
effective vapor barrier at the location where the chim-
ney penetrates to the exterior of the structure. This can
be accomplished by applying a non-hardening water-
proof sealant to the following components:
• Around the chimney at the point where the storm
collar will meet the chimney just above the Flash-
ing.
• Along the vertical seam of the chimney pipe, where
it is exposed to the weather.
• On each nail head on the flashing.
• Around the chimney at the point where the storm
collar will meet the chimney just above the flashing.
Notes:
• On a flat or tarred and graveled roofs, nail and seal
the flat roof flashing to the roof on all sides with
roofing compound.
• Do not put screws through the flashing into the
chimney pipe.
CHIMNEY INSPECTION
Existing chimneys must be inspected before installing
your stove. Consult your local building department for
chimney code requirements. A masonry chimney must
have a code approved liner. This liner must not have
broken or missing pieces. Some non-code masonry
chimneys may be brought up to code by being relined.
(Consult your dealer or qualified chimney sweep). Fac-
tory built chimneys should also be inspected, first for
creosote deposits (which should be removed), and then
for integrity of the stainless steel liner. Look for obvious
bulges in the lining which may indicate the need to re-
place that section (use a bright flashlight). Also, inspect
the attic to see that the chimney has proper clearance
to combustible framing members. For interior masonry
chimneys and most factory built chimneys, this must be
a (2) two inch (51 mm) air space clearance, which must
not be filled with insulation or any other material. An
exterior masonry chimney must have a (1) one-inch
(25.4 mm) air space clearance.
