VENTING
NOTE
: Planning for the venting system should be done in
conjunction with planning for the ductwork, drainage, and
furnace accessories, such as air cleaners and humidifiers.
Begin assembling the venting system AFTER the furnace is set
in place in the required orientation.
Venting for this furnace shall follow all Local codes for category
IV venting systems. This furnace is CSA approved for venting
with PVC/ABS DWV venting systems. This furnace is also CSA
approved for venting the M&G DuraVent
PolyPro
polyproplylene venting systems.
NOTE
: THESE INSTRUCTIONS
DO NOT
CONTAIN
DETAILED INSTALLATION INSTRUCTIONS FOR
POLYPROPYLENE VENTING SYSTEMS. Refer to the
polyproplylene venting system manufacturer’s installation
instructions for the polyproplylene venting system installation.
NOTE
: When using polypropylene venting systems, all venting
materials used, including the vent terminations, must be from
the same manufacturer.
Special Venting Requirements for Installations
in Canada
Installation in Canada must conform to the requirements of
CAN/CSA B149 code. Vent systems
must
be composed of
pipe, fittings, cements, and primers listed to ULC S636. The
special vent fittings, accessory concentric vent termination kits,
and accessory external drain trap available from the furnace
manufacturer 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
(1)
t, PVC Cement for Flue Gas 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 CAN/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.
The authority having jurisdiction (gas inspection authority,
municipal building department, fire department, etc) should be
consulted before installation to determine the need to obtain a
permit.
