General steps of chimney installation
Use only approved chimneys of the same size as the output of
the appliance, which means 6 inches in the case of cookstove.
The chimneys used must be tested according to CAN/ULC S629
M87. The stove can be installed with a masonry chimney
according to ULC S635, ULC S640. The cookstove can be
installed with a masonry chimney according to ULC-S635 and
ULC-S640. The masonry chimney must be equipped with a
stainless steel sleeve and meet the standards for the masonry
chimney with inner sleeve.
Provide a place for sweeping.
It is preferable, if possible, to avoid a chimney built outside of a
house and on an exterior wall, especially in cold regions.
Outside chimneys generally have a less efficient draft. They
can even have down draft since it is hard to heat them enough
so that they can reach their operating temperature. Cold
chimneys have tendencies of greater accumulation of creosote,
less efficient draft and worse efficiency. Draft is proportional to
the total chimney height as well as its temperature. It is
therefore possible to get better draft by increasing the
chimney's height and by reducing the heat loss with insulated
lining. Make sure that all pipe joints are really airtight. A leak
reduces the efficiency of the appliance and could even make
its usage dangerous. . Using a high temperature silicon or
cement to ensure that the smoke pipe joint are airtight. If the
chimney pass through the exterior wall or insulated roof be
sure the hole after installation needs to be airtightness. Use
sealant to make the building airtight.
Note: This is a general chimney installation method. Be
sure to refer to the manufacturer's manual for more details
of installation of your chimney.
1)
Determine the total length necessary for your
chimney.
2)
Make holes into all floors and roof.
3)
If you need to cut a joist, be sure to strengthen the
adjacent joists and frame the hole respecting the
minimum dimensions between combustible materials
and the fireguard. Follow the manufacturer's
instructions supplied with the fireguard. Never cut a
loadbearing joist/beam.
4)
Frame the holes in each level and
attic respecting the minimum
distance recommended by the
manufacturer of your chimney.
Install fireguard in each level.

5)
Frame the hole into the roof.
6)
Install a chimney support and a fireguard in the ceiling
where cook stove is installed.
7)
Stack the prefabricated chimney sections on the
support and exceed the roof.
• The chimney must exceed at least 3 feet (91.4 cm)
from the highest point of the hole in the roof.
• The chimney must also be at least 2 feet over the
highest point on the roof inside 10 feet (304 cm)
radius around the chimney.
• The minimum length of chimney is 12 feet (365.8 cm).
ATTENTION: Be sure the chimney parts are attached
properly and lock onto the chimney support.
Note: A chimney longer than the minimum required
can add more draft and help the operation of the
cook stove. Try the minimum length first then add
section if you need more draft.
8)
Put the roof flashing over the chimney and seal it with
roof caulking.
9)
Nail the roof flashing.
10) Slide the storm collar over the chimney and fix it. Seal
it with high temperature caulking.
11) Lock the chimney cap and install the spark arrestor if
necessary.
