TM
RUTE. BOILERS AND VOLUME WATER HEATERS, 1,000 & 1,200 MBTU/h
with ULC S636, or stainless steel complying with UL 1738. Installations in Canada
require exhaust vent pipe that is certified to ULC S636.
NOTE: The first 12" (30cm) of vent must be CPVC if using a PCV vent system.
Section 5
Intake (air) pipe may be ABS, PVC, CPVC or galvanized material.
Closet and alcove installations do not allow the use of PVC under any circumstances

PUMP REQUIREMENTS

*To calculate max equivalent length, measure the linear feet of the pipe, and add 5
feet (1.5m) for each elbow used.
