2.4 Power vent motor

Caution: Power vent motor must be mounted with vibration mounts and with motor shaft horizontal to prevent motor bearing wear.

1.Remove vibration mounts, nuts and washers from parts bag. Install on power vent motor as shown in Fig. 2.

2.To prevent vibration, securely support power vent motor from ceiling or joist using a plumber’s strap fastened to the vibration mounts. As an alternative means of support, a wall bracket may be used to support the underside of the motor. Observe a 6" clearance to combustibles on all sides of the power vent motor. (Fig. 3)

3.Connect the power vent motor outlet to the inner sleeve of the vent hood (Fig. 4). Use the four pre- punched holes in the outlet collar of the power vent motor as a guide to drill 1/8" diameter holes into the vent pipe. Fasten power vent motor outlet to the vent hood inlet using sheet metal screws. Seal the connection with high temperature silicone sealant.

Note: Any additional vent pipe used between the power vent motor and the vent hood will be under positive pressure during operation. This vent pipe must be single wall galvanized or stainless steel vent pipe. The connections must be sealed with high temperature silicone sealant.

4.Route the control cable from the power vent motor along the ceiling or joists down to the right side of water heater, taking care not to come within 6" of the vent pipe or any other potentially hot surface. In many cases, the gas or water supply piping can be used as a routing path from the ceiling down to the right side of the water heater. Use the supplied nylon ties to secure the cable.
