Termination Requirements for the Provinces of Alberta and
Saskatchewan
The Provinces of Alberta and Saskatchewan require a minimum
unobstructed distance of 4 ft. (1.2 M) from the foundation to the property
line of the adjacent lot for vent termination of any appliance with an
input over 35,000 Btuh. If there is less than 4 ft. (1.2 M) of unobstructed
distance to the property line of the adjacent lot, no type of vent
termination is permitted for appliances with inputs greater than 35,000
Btuh.
There are no additional restrictions on unobstructed distances greater
than 8 ft. (2.4 M). All single, two-pipe and concentric vents may be used,
providing all other Code and manufacturer’s requirements in these
instructions are adhered to. Refer to the appropriate
Vent Termination
section above for locating the vent termination
If the unobstructed distance from the foundation to the property line of
the adjacent lot is no less than 4 ft. (1.2 M) and no greater than 8 ft. (2.4
M), it will be necessary to re-direct the flue gas plume. In this situation, a
concentric vent kit cannot be used. A 2-pipe termination (or single pipe
termination when permitted) that re-directs the flue gas away by use of
an elbow or tee, certified to ULC S636 from the adjacent property line
A13078A
Fig. 49 – Alberta and Saskatchewan Vent Termination
The concentric vent kit currently cannot be modified to attach an elbow
to the vent portion of the rain cap. A tee attached to the rain cap could
potentially direct the flue gas plume toward the intake air stream and
contaminate the incoming combustion air for the furnace.
Refer to
for terminations approved for use in Alberta and
Saskatchewan.
NOTICE
!
RECOMMENDED SUPPORT FOR VENT TERMINATIONS
It is recommended that sidewall vent terminations in excess of 24
inches (.6 M) or rooftop terminations in excess of 36 inches (1 M) in
vertical length be supported by
EITHER
the Direct Vent Termination
Kit shown in
or by field-supplied brackets or supports
fastened to the structure.
WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow the instructions outlined below for each appliance
being placed into operation could result in carbon monoxide poisoning
or death.
For all venting configurations for this appliance and other gas
appliances placed into operation for the structure, provisions for
adequate combustion, ventilation, and dilution air must be provided in
accordance with:
