3.5 Connecting the vent and air intake pipes
The appliance offers 3" connections that accept standard 3" PVC/CPVC and PP pipe. Use reducing
fittings (not bushings) to adapt to smaller diameter pipe. Insert pipe directly into the 3" female fitting,
and secure with the built-in clamp (see image below). For PP, no transition adapter is required. The
vent connection has a second gasket approximately 2.5” below the first 3” PVC/CPVC sized gasket
that will seal to standard 80 mm PP pipe. Care should be taken to ensure that PP pipe is installed so
that it extends past this second gasket.
For PP material exposed to outdoor conditions, follow the venting supplier’s recommendations on
UV protection.
Figure 6 Securing a pipe connection
Combustion air piping - if used - is inserted directly into the 3" connector on the right side. PP pipe
should be inserted firmly into the connector until it cannot go further. The pipe must be secured with
the built-in clamp.
Warning
Ensure that you lubricate the gasket with silicone grease before inserting the venting
material. Fully insert the approved venting material into the boiler's exhaust outlet, and
tighten clamp to ensure the venting connection is locked in place (as shown above).
Venting must be supported in accordance with the applicable code and instructions supplied by the
manufacturers.
Warning
Do not mix PP venting materials from different manufacturers. These venting materials
are designed to be installed as part of a complete system. Failure to comply may result in
severe personal injury or death.
