Before beginning installation review

required clearances for Water Heater,

Power Vent Motor and Vent Hood

Power Vent Kit

CAUTION

Failure to install, maintain and/or operate the

Power Venter in accordance with

manufacturer's instruction may result in

conditions which can produce bodily injury and

property damage.

The Power Venter must be installed by a

qualified installer in accordance with all local

codes or, in their absence, in accordance with

the National Fuel Gas Code (ANSI

Z223.1NFPA #54), the National Electric Code

and The Occupational Health and Safety Act

(OSHA) as applicable.

The Power venter motor shaft must be

mounted horizontally to prevent motor bearing

wear.

Disconnect power supply when making wiring

connections or when working around the fan

blade and motor. Failure to do so may result

in severe personal injury and equipment

damage.

Make certain the power source is adequate for

the fan motor requirements. Do not add the

power venter to a circuit where the total load

is unknown.

AQ-1 Motor is 200 watts- 1.66 amps @ 120vac

Bosch-Aquastar

Follow installation and operating instructions

manual supplied with the water heater.

Before mounting water heater to wall, check

its minimum clearance requirements.

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. Install power vent

motor as close to the termination as

possible to maintain the water heater's

optimal efficiency.

IMPORTANT: FREEZE PREVENTION TO HEATER

In cold climates the vent hood and power vent mo-

tor will not prevent infiltrating cold air to the water

heater when not in use. Be sure to install the sup-

plied backdraft AQ1FLAPPER accessory within the

vent hood on the outside of the building. If not used,

cold air can enter the vent pipe and freeze the heat-

ers heat exchanger when not in use. Such damage

is not covered under the water heater's warranty.

Gas Pressure Switch

Remove the gas pressure switch from the bag in the

carton and the brass 1/4" compression nut fitting which

is meant for the burner manifold tap on the heater, not

the inlet tap on the heater's gas inlet pipe (see p. 3,

Fig B). Also remove the four self-tapping screws and

the two sections of 1/4" diameter aluminum tubing from

the master carton.

The gas pressure switch must be mounted in such a

way that the diaphragm is oriented vertically and the

aluminum tubing pieces can easily reach the manifold

pressure test nipple and the burner respectively.

It must not be mounted inside the heater. See

Figure E p.6

When mounting the Gas Pressure Switch: We

recommend mounting the gas pressure switch vertically

against a wall on the lower left side of the water heater.

See Figure E p.6. Because the cabinet cover is three

sided we do not recommend screwing the gas pressure

switch to the left side of it. Instead, mount the gas

pressure switch vertically against a wall on the lower left

side of the water heater. Installed in this manner all

necessary connections will be within reach and there

will be minimal interference when servicing.
