Vent adaptors are not designed as load-bearing devices, and must not be used to support exhaust vent piping. All vent pipes must be

properly connected, supported, and the exhaust must be pitched a minimum of ¼” per foot back to the appliance to allow drainage of

condensate. Failure to properly support vent piping and follow the information in this statement could result in product damage, severe

personal injury, or death.

D. TIGHTENING APPLIANCE COLLAR TO EXHAUST VENT AND INTAKE PIPE

NOTE: The included 6” length of 3” CPVC pipe MUST BE INSTALLED in the exhaust vent connection BEFORE venting the appliance.

Failure to properly install the included 6” length of 3” CPVC pipe BEFORE venting the appliance could result in product damage, severe

personal injury, or death.

This appliance uses 2” or 3” diameter pipe for exhaust vent and intake pipe. In order to use 2” pipe, it is required to reduce pipe size in

a vertical length of pipe with a reducing coupling (not included). Follow the steps below to install 2” or 3” pipe into the appliance collar.

See Figure 7 for additional details.

1. Clean and dry the appliance connection. DO NOT use primer or cement on the appliance connection.

2. Push the included 6” length of CPVC pipe into the connection until it touches the bottom of the fitting.

3. Tighten the clamps using a screwdriver.

4. Ensure the pipe is secure before continuing installation.

5. For 2” installations, install a reducing coupling in a vertical section of pipe. See Figure 8.
