NOTE: FOLLOW REQUIREMENTS IN FIGURES F & G ON THIS PAGE BEFOREINSTALLING VENT HOOD, THEN USE TEMPLATE ON PAGE 13 TO CUT HOLE.CAUTIONFailure to follow these installationinstructions may violate applicablenational and/or local codesThe vent system must terminate so that properclearances are maintained as cited in the National FuelGas Code, ANSI Z223.1"The exit terminals of mechanical vent system shall belocated not less than 7 feet above grade when locatedadjacent to a public walkway. The venting system shallterminate at least 3 feet above any forced air inlet within 10feet. The venting system shall terminate at least 4 feetbelow, 4 feet horizontally from or 1 foot above any door,window or gravity air inlet into any building."Also, "The vent terminal shall also not be installed closerthan 3 feet from the inside corner of an L-shaped structure,or less than 1 foot above grade."FIGURE FPOWER VENT FAN AND MOTORCode RequirementsPower vent installation must be in accordance with thefollowing requirements of the National Fuel Gas Code:• All portions of the vent system under positivepressure during operations (on the outlet sideof the power venter) shall be designed andinstalled so as to prevent leakage of flue orvent gasses into building.• Provisions shall be made to interlock theappliance(s) to prevent the flow of gas to themain burners when the draft system is notperforming so as to satisfy the operatingrequirements of the equipment for safeperformance.2. Power venter must be mounted with motorshaft horizontal to prevent motor bearingwear.3. Power venter housing is single walled. A 6"clearance from combustible material must bemaintained. (See Figure G)4. Whenever possible, allow for a minimum of12" vertical rise off the top of the Aquastarbefore the vent piping makes a 90º elbow tothe horizontal. Observing this guideline willhelp prevent nuisance shut downs.FIGURE Gv6"vInstallation Restrictions1. Power venter should be installed as close tothe termination of the vent system as possibleto obtain optimal appliance efficiency and toprevent flue gas leakage.v6"vv6"v7
INSTRUCTIONS(DO NOT BEGIN THESE PROCEDURESUNTIL VENT HOOD HAS BEEN IN-STALLED)1. Remove vibration mounts, nuts and washersfrom parts bag. Install on power venter asshown in (Figure H).2. To prevent vibration, securely support powerventer from ceiling or joist using a plumber'sstrap or wire fastened to the vibration mounts.As an alternative means of support, a wallbracket may be used to support the undersideof the motor. (NOTE: Plumbers strap, wire orwall bracket must be supplied by installer.)6. Support the vent pipe in accordance with ventmanufacturer's instructions. Vent pipe is notsupplied in the power venter package, exceptfor the 5" to 4" reducer vent pipe in the AQ-1.Observe the clearances associated with theclass of vent pipe used.FIGURE H3. Connect the power venter outlet to the innersleeve of the vent hood. If you need to addsections of 4" Class B vent pipe between thepower venter and the vent hood, first check if itis permissable with local codes. Use the 4 prepunchedholes in the outlet collar of the powerventer as a guide to drill 1/8" diameter holesinto the vent pipe. Fasten power venter outletto the vent hood inlet using sheet metal screws.4. All vent pipe connections after the powerventer will be under positive pressure duringoperation. These connections must be sealedwith high temperature silicone sealant oraluminum vent pipe tape supplied by theinstaller.5. Install properly sized vent pipe connectionsfrom the power venter inlet to the Aquastar'soutlet avoiding elbows, wherever possible.Allow a minimum of 12" vertical rise off thetop of the Aquastar before the vent makes a90º elbow to the horizontal. Observe the ventpipe length restrictions mentioned earlier.NOTE: The AQ-1 provides a 5" to 4" reducervent pipe which is applicable to Aquastar125X/B models only. The AQ-2 does notprovide a 6" to 4" reducer vent pipe and mustbe provided by the installer.Installation - Electrical1. Route the control cable from the power venterfan along the ceiling or joists down to the gaspressure switch, taking care not to comecloser than 6" to the vent pipe or any otherpotentially hot surface. In many cases, thegas supply piping can be used as a routingpath from the ceiling down to the controls,using the supplied nylon ties to secure thecable.2. Connect the BLUE wire from the jacketedpower vent cable onto the normally openterminal of the gas pressure switch.(See Figure I)8
