INSTRUCTIONS

(DO NOT BEGIN THESE PROCEDURES

UNTIL VENT HOOD HAS BEEN

INSTALLED)

Remove vibration mounts, nuts and washers

from parts bag. Install on power venter as

shown in (Figure H).

To prevent vibration, securely support power

venter from ceiling or joist using a plumber's

strap or wire fastened to the vibration mounts.

As an alternative means of support, a wall

bracket may be used to support the underside

of the motor. (NOTE: Plumbers strap, wire or

wall bracket must be supplied by installer.)

Connect the power venter outlet to the inner

sleeve of the vent hood. (See page 6 for vent

piping requirements). Use the 4 pre-punched

holes in the outlet collar of the power venter as

a guide to drill 1/8" diameter holes into the vent

pipe. Fasten power venter outlet to the vent

hood inlet (or single wall pipe, depending on if

additional piping is being used between the

venter and the hood) using sheet metal screws.

Any vent pipe connections used after the power

venter (between it and the vent hood) will be

under positive pressure during operation. The

vent pipe must be galvanized or stainless steel

single wall vent pipe. The connections must be

sealed with high temperature silicone sealant or

aluminum vent pipe tape supplied by the

installer.

Install properly sized vent pipe connections

from the power venter inlet to the water heater's

outlet, avoiding elbows wherever possible.

Position the 5" to 4" reducer pipe on top of the

water heater first and then connect a 4" 90º

elbow to begin the horizontal run. Observing

this guideline will help to establish a proper

draft. When using an AQ-1 the maximum

horizontal distance from the water heater to the

power vent motor is 100 feet. Subtract 10 feet

for each added elbow.

Support the vent pipe in accordance with vent

manufacturer's instructions. Vent pipe is not

supplied in the power venter package, except

for the 5" to 4" reducer vent pipe in the AQ-1.

Observe the clearances associated with the

class of vent pipe used.

IGURE

Installation - Electrical

Route the control cable from the power venter

fan along the ceiling or joists down to the gas

pressure switch, taking care not to come

closer than 6" to the vent pipe or any other

potentially hot surface. In many cases, the

gas supply piping can be used as a routing

path from the ceiling down to the controls,

using the supplied nylon ties to secure the

cable.

Connect the BLUE wire from the jacketed

power vent cable onto the normally open

terminal of the gas pressure switch.
