Special Venting Requirements for Installations in Canada
Installation in Canada must conform to the requirements of CSA
B149 code. Vent systems must be composed of pipe, fittings,
cements, and primers listed to ULC S636. The special vent fittings
and accessory concentric vent termination kits and accessory
external drain trap have been certified to ULC S636 for use with
those Royal Pipe and IPEX PVC vent components which have been
certified to this standard. In Canada, the primer and cement must be
of the same manufacturer as the vent system – GVS-65 Primer
(Purple) for Royal Pipe or IPEX System 636, PVC/CPVC Primer,
Purple Violet for Flue Gas Venting and GVS-65 PVC Solvent Cement
for Royal Pipe or IPEX System 636
Venting, rated Class IIA, 65 deg C. must be used with this venting
system - do not mix primers and cements from one manufacturer with
a vent system from a different manufacturer. Follow the
manufacturer’s instructions in the use of primer and cement and
never use primer or cement beyond its expiration date.
The safe operation, as defined by ULC S636, of the vent system is
based on following these installation instructions, the vent system
manufacturer’s installation instructions, and proper use of primer
and cement. All fire stop and roof flashing used with this system must
be UL listed material. Acceptability under Canadian standard CSA
B149 is dependent upon full compliance with all installation
instructions. Under this standard, it is recommended that the vent
system be checked once a year by qualified service personnel.

Vent Termination Clearances
1. The Province of Alberta requires a minimum unobstructed
distance of 4 ft. (1.2m) from the foundation to the property line of
the adjacent lot for vent termination of any appliance with an
input over 35,000 btuh. This means, if there is less than 4 ft.
(1.2m) 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.
The Province of Alberta does not interpret any restrictions on
unobstructed distances greater than 8 ft. (2.4m). This means
that all single, two-pipe and concentric vents may be used,
providing all other Code and manufacturer’s requirements are
adhered to.
The requirement is to re-direct the flue gas plume when the
unobstructed distance from the foundation to the property line of
the adjacent lot is no less than 4 ft. (1.2m) and no greater than 8
ft. (2.4m).
In venting situations where the unobstructed distance from the
foundation to the property line of the adjacent lot is between 4 ft.
(1.2m) and 8 ft. (2.4m), the concentric vent kit cannot be used.
The concentric vent kit cannot be modified to attach a tee or
elbow to the vent portion of the rain cap. A tee or elbow 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.
In a venting situation where the unobstructed distance from the
foundation to the property line of the adjacent lot is between 4 ft.
(1.2m) and 8 ft. (2.4m), a 2-pipe termination (or single pipe when
permitted) must be used.
2. With the exception of The Province of Alberta, Canada,
determine termination locations based on clearances specified
in furnace installation instruction, and following steps as shown
in Figure 2, Figure 5 through Figure 8.
3. The vent termination must be located at least 12″ (304.8mm)
above ground or normally expected snow accumulation levels.
4. Do NOT terminate over public walkways. Avoid areas where
condensate may cause problems such as above planters,
patios, or adjacent to windows where steam may cause fogging.
5. The vent termination shall be located at least 3′ (.9m)
horizontally from any electric meter, gas meter, regulator, and
any relief equipment.
6. The vent termination is to be located at least 3′ (.9m) above any
forced air inlet located within 10′ (3m); and at least 10′ (3m) from
a combustion air intake of another appliance, except another
direct vent furnace intake.
7. In Canada, refer to Special Venting Requirements for
Installations in Canada and the Province of Alberta
requirements and the National Standards of Canada, Natural
Gas, Propane Installation Codes (NSCNGPIC).
