CONNECTING PVC, ABS OR CPVC PIPE VENT TO BLOWER

2. If there is to be a vertical run of vent from the blower, the 3" PVC or ABS pipe must be attached to the blower using 3 sheet metal screws. Additionally, you must sea! all joints using a suit- able silicone sealer such as GE
The 3" PVC, ABS or CPVC Schedule 40 vent pipe can be run from the water heater through the wall or from the wall to the
water heater, whichever is most convenient. The vent pipe must extend a minimum of IV_,"through the exterior wall. Extending the vent cap as far as possible from the surface of the exterior wall will help minimize discoloration of the wall in this area which may be caused by the flue gases. Note that the inside col- lar must be slipped over the vent piping before locating the pipe through the wall. Before securing the inside and outside collars to the wall, use a silicone sealer between pipe and opening to insure a water and air tight seal.
