Install the appropriate diameter Centrotherm ISTAGL PVC Termination Adapter on the end of the last pipe.
Install a PVC coupling onto the male gasketed end of the Centrotherm PVC Termination Adapter. A reducer coupling
may be needed to use the supplied vent terminals if a larger pipe diameter size was used. Cement the straight section
of PVC pipe to the PVC pipe coupling. Install the PVC pipe to exit the wall or roof, and then cement the vent terminal
onto the PVC or CPVC pipe. Refer to the venting section of the water heater Installation and Operating Instruction
manual for the appropriate solvent and cement to use. The exhaust vent terminal for the EF model series is shown. Use
the vent terminals supplied with the water heater. See the following photos.
WARNING
A Centrotherm ISTAGL series PVC Vent Termination Adapter must be used at the end of the last section of
polypropylene vent pipe to connect to the PVC pipe coupling. The arrow must point toward the vent terminal. DO
NOT USE THE SAME PVC ADAPTER THAT IS USED TO CONNECT TO THE WATER HEATER.
