CHIMNEY
Use only approved chimney of the same dimensions as the appliance exit, which means
you should use a 6 inch diameter chimney for your
GRIZZLY Furnace
. A Chimney must
be tested upon the ULC S629 CSA, UL103 norms. The GRIZZLY
Furnace
wood
appliance can be connected to a masonry chimney following the ULC S635, ULC S640
and the UL 1777 norms. Do not forget to keep space for the sweeping of the chimney.
If possible, it is preferable to avoid an outside chimney or built on an exterior wall,
especially in cold areas. Outside chimneys generally have a less efficient draught. They
can even have an inverse draught because it is hard to heat them enough to reach
operating temperature. A greater accumulation of creosote, a less efficient draught and
a weaker performance are the typical problems of cold chimney. Draught is proportional
to the total chimney height as well as its temperature. It is therefore possible to get a
better draught by increasing the chimney's height and by reducing the heat loss with an
insulated lining. The chimney has to be installed with a stainless steel lining. Make sure
that all smoke pipe joints are really airtight. Leaking reduces the efficiency of the
appliance and could even make its utilization dangerous.
INSTALLATION
A good installation is extremely important for a safe and efficient use of your J.A. Roby
Inc. appliance. If you are in doubt regarding the installation of the appliance, contact
professional installation service.
1. Place an incombustible plate underneath the appliance which exceeds 18 inches
(46 cm) at the front and 8 inches (20 cm) on the sides.
2. Withdraw firebricks placed inside the appliance in order to reduce the weight and
to facilitate the installation.
3. It is possible to make 4 round-shaped openings of 6 inch diameter or 2 round-
openings of 8 inch diameter on the plenum while respecting the air pressure and
air volume.
4. The free space shall not be reduced except under the approval of the responsible
authorities for the application of the building code.
5. Install the chimney and a wall thimble for an installation passing through a wall
(follow the instructions of the chimney manufacturer).
6. Reinstall the firebricks in accordance with the recommended instructions for your
model.
7. The appliance should not be connected to a hot air conduct which has been
already existed or another generator of hot air.
