MOUNTING POWER VENTER
1. To facilitate installation and reduce vibration, we have included 2 mounting brackets, 2 rubber isolators and 2 rubber
grommets. One of the brackets may be used temporarily as a “third hand” to support the Power Venter while
positioning it for permanent installation. Install the brackets as shown below.
NOTE: The Power Venter may be mounted in any position as long as the shaft of the motor remains horizontal.
2. Connect outlet of Power Venter to inner sleeve of vent hood. Sections of vent pipe are
permitted between Power Vent and Vent Hood but all connections after the Power Venter will
be under a positive pressure during operation. These connections must be sealed with high
temperature silicone sealant or aluminum vent pipe tape supplied by installer.
3. Using the holes as a guide, attach vent pipe to inlet collar using sheet metal screws. Install
properly sized vent pipe sections from Power Venter inlet to appliance outlet avoiding elbows
wherever possible and using only tapered transitions.
4. Support vent pipe in accordance with vent manufacturer’s instructions.
ELECTRICAL
Route the 25’ control cable supplied with the Power Venter back to the water heater controls along the ceiling joists, taking care not to
come closer than 6” to the vent pipe or any other potentially hot surface. In most cases, the gas supply line may be used as a routing
path from the ceiling to the water heater controls, the supplied nylon straps may be used to secure the cable.
NOTE: If the distance between the Power Venter and the heater controls is greater than the length of the cable, splice a section of 2
conductor PVC sheathed, 105 degree C thermostat cable to the supplied cable. Make sure the color coded leads remain consistent.
An NEC approved accessible junction box must be used to contain the splice. Splices shall be made mechanically secure and insulat-
ed with tape or fixture type splicing connectors may be employed. Strain relief hardware contained within the NEC approved junction
box shall be utilized.
The Power Venter operates on 110/115 VAC, therefore a grounded outlet must be within reach of the six foot power cord supplied with
Power Venter. The flexible power cord supplied with the unit may only be used where local codes permit. If local codes do not permit
the use of flexible power cord, follow steps below.
1. Remove the electrical box cover, flexible cord and strain relief from the enclosure.
2. Install suitable conduit fitting in enclosure and splice field wiring into existing wiring using code authorized method (wire nuts, etc.).
3. Replace electrical box cover.
