Whirlpool Gold WFD193 Installation Instructions Manual page 13

Canadian Venting Requirements
In Canada, venting must conform to the requirements of the current CAN/CSA-B149.1-05 Installation Code. Use only CSA-listed, ULC-
S636 compliant 2" or 3" diameter PVC, PVC ceill core or ABS pipe, solvent cement and fittings throughout. The certified piping should
be clearly marked with the ULC Std "S636" on the pipe and fittings. Follow the manufacturer's instructions for cutting, cleaning and
solvent cementing PVC and/or ABS.
The vent can be run through an existing unused chimney provided the space between the vent pipe and the chimney is insulated and
closed with a weather-tight, corrosion-resistant flashing.
Schedule 40 PVC Cellular Core (Foam Core) Plastic Pipe is not approved for use in Canada. CSA does not have a Reference Standard
for Cellular Core PVC Plastic Pipe.
Direct Vent Applications
Refer to the following tables for applicable length, elbows and pipe diameter for construction of the vent/flue and combustion air intake
pipe systems of a direct vent (dual pipe) installation. The number of elbows tabulated represents the number of elbows and/or tees in
each vent/flue and combustion air intake pipe. Elbows and/or tees used in the terminations must be included when determining the
number of elbows in the piping systems.
If the combustion air intake pipe is to be installed above a finished ceiling or other area where dripping of condensate will be
objectionable, insulation of the combustion air pipe may be required. Use ¹⁄₂" (1.3 cm) thick closed cell foam insulation where required.

Minimum length of each vent/flue and combustion air intake
pipe is 5 ft (1.5 m) and one elbow/tee.
2¹⁄₂" (6.4 cm) or 3" (7.6 cm) diameter pipe can be used in
place of 2" (5.1 cm) diameter pipe.
