installation and operating instructions for aq-1 and aq-2 power vent ...

Before beginning installation reviewrequired clearances for Aquastar,Power Vent Motor and Vent HoodPower Vent KitCAUTION1. Failure to install, maintain and/or operate thePower Venter in accordance withmanufacturer's instruction may result inconditions which can produce bodily injury andproperty damage.2. The Power Venter must be installed by aqualified installer in accordance with all localcodes or, in their absence, in accordance withthe National Fuel Gas Code (ANSIZ223.1NFPA #54), the National Electric Codeand The Occupational Health and Safety Act(OSHA) as applicable.3. The Power venter motor shaft must bemounted horizontally to prevent motor bearingwear.4. Disconnect power supply when making wiringconnections or when working around the fanblade and motor. Failure to do so may resultin severe personal injury and equipmentdamage.5. Make certain the power source is adequate forthe fan motor requirements. Do not add thepower venter to a circuit where the total loadis unknown.Aquastar1. Follow installation and operating instructionsmanual supplied with the Aquastar.2. Before mounting water heater to wall, checkits minimum clearance requirements.3. When using an AQ-1 or AQ-2 the maximumhorizontal distance from Aquastar to dischargeis 100 feet. Subtract 10 feet for each addedelbow. Install power venter motor as closeto the termination as possible to maintainthe Aquastar's optimal efficiency.FREEZING CONCERNS TO AQUASTAR:The vent hood and power vent will not prevent infiltrationof cold air to the Aquastar when not in use.Be sure to correct any causes of negative air pressurein room. If this is difficult add additionalhorizontal lengths of 4" vent pipe between powervent and the Aquastar to warm any infiltrating air.Gas Pressure SwitchRemove the gas pressure switch from the carton.Also remove the brass fittings (170vp: 1/8" NPT by1/4"compression fitting and nut), (125X/B models:manifold pressure tap fitting and 1/4" compressionnut). The four self-tapping screws and the two sectionsof 1/4" diameter aluminum tubing from themaster carton.The gas pressure switch is to be mounted in such away that the diaphragm is oriented vertically and thealuminum tubing pieces can easily reach the manifoldpressure test nipple and the burner respectively.It must not be mounted inside the heater. See p.6When mounting to an Aquastar 170vp: We recommendmounting on the lower right side of theAquastar. Both sides of the switch bracket can screwinto the side panel. Installed in this manner allnecessary connections will be well within reach andthere should be minimal interference when servicing.The four screws provided are self-tapping. Their 1/2"length assure that components inside the Aquastar willnot be damaged upon penetration. You must notmount the switch where the screws could penetratethe heat exchanger tubing inside theAquastar.When mounting to Aquastar 125X/B models: Werecommend mounting the gas pressure switch verticallyagainst a wall on the lower left side of Aquastar125X/B models. Because the cabinet cover is threesided we do not recommend screwing the gas pressureswitch to the left side of it. Instead, mount the gaspressure switch vertically against a wall on the lower leftside of Aquastar 125X/B models. Installed in thismanner all necessary connections will be within reachand there will be minimal interference when servicing.See p.62
