The vent pipes are on the exhaust side of the exhaust fan and are under pressure. Care
must be taken to ensure that all the joints are completely sealed to prevent any leakage of
exhaust fumes and smoke into the house. If you smell smoke, the venting has not been
properly sealed. Use only high temperature RTV silicone for sealing.
Aluminum tape is
not considered an adequate sealant. At least 3 screws are needed for securing all vent pipe
joints.
The venting of this heater is not allowed to pass through any closets, concealed spaces,
floors, ceilings or attic spaces. If the venting must go through a wall or combustible
partition, the installation must conform to the Installation Code for Solid Fuel Burning
Appliance and Equipment CAN / CSA -B365. For more detailed venting information,
please refer to your venting manufacturer’s instructions.
6.2 Exhaust Vent Termination Requirements
1. It is highly recommended that the venting include a minimum 3’ vertical
rise before termination. This will help prevent any odor of smoke in the
house during a power failure.
2. The exhaust vent must terminate into an open space. Under no circum-
stances is the vent allowed to terminate into closed or semi-closed
spaces. Venting into a garage, under a sun deck, porch or any other
space where the concentration of fumes may occur is prohibited.
3. The exhaust vent must be at least:
* 4 feet (1.2 m) below
* 4 feet (1.2 m) horizontally from
* 1 foot (0.3m) above
any opening in the building such as doors, windows, ventilation air
intakes, etc.
4. The exhaust vent opening must be a minimum of:
* 12 inches (0.3m) from the ground
* 24 inches (0.61m) from any combustible surface i.e. fence, plant, etc.
* 7 feet (2.1 m) from any public walkway
5. The exhaust air is EXTREMELY HOT. Caution must be taken to avoid
contact with children, people, plants, animals, or any other object that
may be affected by heat. It is recommended to use a vertical pipe to
discharge the hot air at a safe elevation.
6. Vertical installations must have an approved vertical vent cap and
horizontal installations must have an approved horizontal vent cap.
Areas where severe wind conditions exist and vent caps are exposed to
unprotected open areas additional protection (especially in horizontal
installations) must be provided.
