Air Intake Installation Instructions
Sparingly apply Centrocelin included in the vent kit to
the gasket or male end of vent pipe to assemble the
common venting system easily.
1
Install a 3" PVC to PP adapter on the top of the water
heaters.
2
Install a 87° elbow to the adapter. For room air intake
option, this step completes air intake installation for one
water heater.
3
Connect a feeder of a branch tee to the open end of the
elbow.
4
Connect the branch tee to another branch. Repeat
steps 1 to 2 for room air intake option, or repeat steps
1 to 4 for direct vent until all air intake branch tees are
connected.
5
Connect a tee cap to the end of the air intake common
vent trunk line.
CAUTION:
Use Rheem approved InnoFlue® PP. No other vent material
is permitted for common venting. For Canada, installations
must follow ULC-S636 for exhaust venting. Also, all pipe,
fittings and procedures must conform to ULC-S636 and vent
manufacturer specifications.
NOTICE:
DO NOT use cement for InnoFlue® PP.
