SECTION IV: INSTALLATION
The following materials are approved for use as the vent and combustion air intake piping:
• PVC (DWV, ASTM-D2665 or CSA B181.2)
• PVC (Schedule 40, ASTM-D1785 or CSA B137.3)
• PVC (SDR Series, ASTM-D2241 or CSA B137.3)
• CPVC (Schedule 40, ASTM-F441 or CSA B137.3)
• CPVC (SDR Series, ASTM-F442)
• ABS (Schedule 40, DWV, ASTM-D2661 or CSA B181.1)
• AL29-4C Stainless Steel
• PVC IPEX 1738 (UL 1738, ASTM D2665)
In Canada, check local codes to ensure that SDR series is approved for use. SDR is not
approved for all installations in Canada.
The following materials are approved for use for the fittings in the vent and combustion
air intake systems:
• PVC (Schedule 40 DWV, ASTM D2665)
• CPVC (Schedule 40, ASTM F438)
• ABS (Schedule 40 DWV, ASTM D2661)
• AL29-4C Stainless Steel
• PVC IPEX 1738 (UL1738, ASTM D2665)
The use of cellular core PVC (ASTM F891), cellular core CPVC, or Radel® (polyphenylsul-
fone) in non-metallic vent pipe and systems is prohibited. Covering non-metallic vent
pipe and fittings with thermal insulation is prohibited.

NOTICE
Installations in Canada must conform to the requirements of CSA B149 code. Plastic
vent systems must be assembled with pipe, fittings, cements, and primers listed to
ULC S636. Components of this listed system shall not be interchanged with other vent
systems or unlisted pipe/fittings. In Canada, the primer and cement must be of the
same manufacturer as the vent system; do not mix primers and cements from one
manufacturer with a vent system from a different manufacturer. The supplied plastic
pipe/fittings are certified as part of the water heater.
