Installing the water heater:Min. 12" (30 cm) Above Roof 1Vertical Vent Termination LocationOnly Rheem approvedtermination and partsshould be used duringinstallation.Vent PipeThrough RoofMin. 12" (30 cm) Above Anticipated Snow Level.Max. 24" (60 cm) Above Roof (Without Additional Support)The location of the vent terminal depends on the followingminimum clearances and considerations (see diagram at left):Minimum twelve (12) inches (30 cm) above roof. 2Minimum twelve (12) inches (30 cm) above anticipatedsnow level.Maximum twenty-four (24) inches (60 cm) above roof levelwithout additional support for vent.Four (4) feet (1.2 m) from any gable, dormer or otherroof structure with building interior access (i.e., vent,window, etc.).Ten (10) feet (3 m) from any forced air inlet to the building.Any fresh or make-up air inlet such as a dryer or furnacearea is considered to be a forced air inlet. 32 For installations in Canada 18" (45.7 cm).1Min. 18" (46 cm) Above Roof for installations in Canada.3 For installations in Canada 6' (1.8 m) .Notice: Only Rheemapproved terminationand parts should be usedduring installation.Notice: Follow ventmanufacturer’s installationinstructions and theirrecommended clearances tocombustibles as required.Vertical Vent InstallationA fire stop plate should be installed at everypenetration of a floor or ceiling if the ventis not running in a fire-rated shaft.

If required, use silicone sealantat the point the vent connector joins thewater heater.Install adequate flashing where the ventpipe passes through the roof. Determine thevent terminal height and install the vent pipeaccordingly. Refer to the diagram above forproper vent terminal height.The vent roof system must terminate at least1 foot (30 cm) above the roof line and at least2 feet (61 cm) higher than any portion of thebuilding within 10 feet (3 m).Install supports every 5 feet (1.5 m) verticallyalong the vent pipe route. Vertical supportsare required after every transition to verticaland are required after every offset elbow.When the vent is free-standing and penetratesa roof/ceiling, another means of support mustbe used at a second location.Follow the vent manufacturer’s recommendedinstallation instructions provided with thevent purchased from the manufacturer.1/4" per foot upward slope1" (2.5 cm) ClearanceFirestop2'(61 cm)MaxSupportHangerCondensateTrapTo Drain.

Ifsweat connections are used,sweat tubing to adapterbefore fitting adapter tothe water connections onheater. Any heat appliedto the water supply fittingswill permanently damagethe internal componentsof the water heater.Notice: Due to coldenviroments, ice maypotentially accumulate atthe water connections. Inthis case, please insert thepower cord of the waterheater into an electricaloutlet. The ice should meltwithing approximately 10minutes and at this time thewater connections can bemade.Mounting the Water HeaterMake sure the location of the appliance allowsfor easy access and operation.Wall studs should be utilized when mountingthe water heater to the wall. Alternately, asuitable piece of wood may be placed insideor outside of the wall to span the distancebetween the wall studs. Fasten the waterheater mounting brackets to the wood.In case of dry wall or concrete wall, usedrywall anchors or lag bolts.The water heater requires 120VAC/60Hz.Have a receptacle with ground terminal nearthe water heater. The length of the powersupply cord is 6 feet (1.8 m).Install a wood screw for the upper bracketwith a clearance of 1/8” (.32 cm) between thewall and the screw head. Hang the center ofthe upper bracket on the screw.Using a wood screw and a washer, affix theThermal ExpansionA thermal expansion tank will be required ifthe water heater is installed in a closed loopsystem to prevent damage to heater, relatedpiping and relief valve. Replacing the reliefvalve will not correct the problem! Theexpansion tank is designed with an air cushionbuilt in that compresses as the system pressureincreases, thereby relieving the over pressureWater Supply ConnectionsPlumbing should be carried out by a qualifiedplumber in accordance with local codes.Use approved plumbing materials only.The diameter of the pipe lines should be aminimum of 3/4”.To conserve energy and to prevent freezing,insulate both cold and hot water supplylines. DO NOT cover the drain or pressurerelief valve.To ensure proper operation of the waterheater, the following water pressure guidelinesshould be followed:● Operation of the water heater requires theminimum water pressure of 14 psi (97 kPa)and a minimum water flow rate of 0.66gpm (2.5 lpm).● A water pressure of 40 psi (276 kPa) isrequired to achieve maximum flow rate.● To maintain proper performance, ensuresufficient water supply pressure. Thelower bracket to the wall (Left and Right).Repeat to affix the top bracket.The brackets can be adjusted to change thedistance between the back of the applianceand the wall within the range of 3/8” (.95 cm)to 1-1/2” (3.8 cm).Loosen the adjustment screws of both the topand the bottom brackets to adjust the distance(See diagram below).TOPBracketAdjustment ScrewsAdjustment ScrewsBracket BOTTOMThe image above may differ in appearancefrom your water heater.condition and eliminating the repeatedoperation of the relief valve. Other methodsof controlling thermal expansion are alsoavailable. Contact your installing contractor,water supplier or plumbing inspector foradditional information regarding this subject.Required Water Pressure = Min. OperatingWater Pressure (14 psi [97 kPa]) + PipePressure Loss + Faucet and ShowerPressure Loss + Safety Margin (more than5 psi [34 kPa]).● To supply hot water to upper floors,additional water pressure (0.44 psi/ft[10 kPa/m]) must be ensured. Themeasurement should be calculated by thedistance between the water inlet of thewater heater (ground level) to the hotwater faucet (upper floor level).● Well water systems should be set to ensurea minimum system pressure of 40 psi (276kPa). The pressure should remain stableduring the operation of the water heater.● When the water is supplied from a watersupply tank, the height of the tank and thediameter of the pipes and their relationto water pressure should be taken intoconsideration. Gravity water pressure isnot recommended.15AP14558-1 (09_08) DV 66 Manual.indd 159/17/2008 3:07:59 PM
