Brackets (2) with nuts and washers Gas Pressure Switch Packet 1. Gas pressure switch 2. Self-tapping mounting screws (4) 3. Manifold pressure tap fitting with 1/4" compression nut and sleeve 4. 1/4" by 40" aluminum tubing (2) Power Vent Kit 1. Power venter (HSUL-1 Series containing integrated 24v control circuit) including 25 foot control cable with 1/4" quick connect ends and an HPN 6 foot power cord 2. Nylon ties 1 Before beginning installation review required clearances for Water Heater, Power Vent Motor and Vent Hood Power Vent Kit CAUTION 1. 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. 2. 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. 3. The Power venter motor shaft must be mounted horizontally to prevent motor bearing wear. 4. 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. 5. 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 1. Follow installation and operating instructions manual supplied with the water heater. 2. Before mounting water heater to wall, check its minimum clearance requirements. 3. 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 motor will not prevent infiltrating cold air to the water heater when not in use. Be sure to install the supplied 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 heaters 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. 2 FIGURE B ROUTE TUBING TO PRESSURE TAP PORT ON THE HEATER'S BURNER MANIFOLD ROUTE TUBING TO BURNER AREA OR ATMOSPHERIC VENT 125B MODEL SHOWN FIGURE A MANIFOLD TAP PRESSURE TAP-GAUGE PORT (WHERE HEATER'S BURNER MANIFOLD PRESSURE CAN BE MEASURED) INSTRUCTIONS (SEE DIAGRAMS ABOVE) 1. Mount gas pressure switch by securing it to the chosen location with a screw in each one of the four mounting holes. 2. Use a tube cutter to make a clean cut (not crimped) at each end of the two lengths of the 1/4" aluminum tubing. One tube must be long enough to reach from the fitting marked "connect to gas valve" to the pressure tap port on the heater's burner manifold (Not to the inlet gas pressure port of the water heater since there will be constant gas pressure there). The tube must be long enough to enter the bottom of the water heater front cover and attach to the burner ma...
