This kit is required to vent the Riva boiler using PVC/CPVC pipe. The kit includes a boiler

connection adapted for PVC/CPVC. When venting with PVC/CPVC this boiler adapter is

required in addition to one of the terminations on the following pages.

Canada: All PVC/CPVC pipe, ttings, and cement must be approved to ULC S636. Do

not mix pipe and joining compounds from different manufacturers as this can

result in an unsafe condition and void the certication.

Installation:

• Attach the collar (C) from the adapter kit to the top of the boiler using the supplied screws.

• Insert the boiler adapter (B) into the collar. Check that the exhaust gasket (D) is installed on

the outlet of the boiler rst.

• Once the adapter is positioned in place, tighten the clamp on the collar and install the

supplied self tapping screw through the pre drilled hole on the collar.

• Insert the PVC adapters (A) into the boiler adapter (B).

• Slide the CPVC/PVC pipe into the PVC adapters (A), do not use any solvents or cement on

this connection. It is a gasket connection that requires no sealing.
