All venting material in
Canada must be
ULC S636 approved
.
See Note 4 below for
appropriate temperature
applications.
All plastic Vent materials
installed on gas fired
appliances in CAN/US must
meet the Standards listed in
Table 3.1. Failure to
comply could result in fire,
serious injury or death.
Notes:
1
Refer to Table 3.2 for Allowable Vent and Air-Intake Pipe Sizes and Lengths.
2
Closet/alcove installations in US and Canada require approved
CPVC
vent pipe, fittings, cements, and primers.
3
The Air-Intake does not require high temperature pipe material. Check applicable local codes for acceptable materials.
4
ULC S636 PVC is approved for flue gas temperatures up to 149
o
F (65
o
C) and must only be used for low temperature
applications. High temperature applications requiring appliance supply water temperatures greater than 140
o
F (60
o
C)
must use ULC S636 approved CPVC.
Mandatory Pre-commissioning Procedure for Plastic Venting
Do not apply power to the appliance prior to Step 4 in the Mandatory Pre-commissioning Procedure for
Plastic Venting.
1.
Working with the power turned off to the appliance, completely install the vent and air intake system, securely cementing
joints together. If possible, allow primers/cements to cure for 8 hours before firing the burner. If curing time is less than 8
hours, proceed with Steps 2 through 6.
2.
Maintain the appliance gas supply shut-off valve in the off position.
3.
Disconnect electrical leads to the Hot Surface. Ensure the cables are placed in a fashion where they will not arc to ground or
other conductor.
4.
Turn power on to the appliance and apply a heat demand.
5.
Allow for 3 complete trials for ignition, consisting of pre and post purge of the combustion blower, until an ignition lockout
occurs. Repeat the process two more times (i.e. 9 complete ignition sequences in total).
6.
Turn power off and reconnect the electrical leads to the Igniter.
