MIXING VALVE USAGE
Thisappliance has been design certified as complying withAmerican
NationalStandard/CSAStandardforwaterheaters and is considered
suitablefor:
Water (Potable) Heating and Space Heating: All models are
consideredsuitable for water (potable) heatingandspace heating.
HOTTERWATERCANSCALD:
Water heaters are intended to produce hot water. Water heated to a
temperature which will satisfy space heating, clothes washing, dish
washing,and other sanitizingneeds can scaldand permanently injure
you upon contact. Some people are more likely to be permanently
injured by hot water than others. These include the elderly, children,
the infirm, or physically/mentally handicapped. If anyone using hot
water in your home fits into one of these groups or if there is a local
code or state law requiring a certain temperature water at the hot
watertap, thenyoumust takespecialprecautions. In additiontousing
the lowest possible temperature setting that satisfies your hot water
needs, a means such as a *Mixing Valve, shall be used at the hot
watertapsused by these peopleor at the water heater. Mixing valves
areavailableatplumbingsupplyorhardwarestores. ConsultaQualified
Installer or Service Agency. Follow mixing valve manufacturer’s
instructionsfor installation of the valves. Before changing the factory
settingonthe thermostat,readthe “TemperatureRegulation”sectionin
thismanual, see Figure 20.

FACTSTO CONSIDERABOUT THELOCATION
Carefullychooseanindoor locationfor thenew waterheater,because
the placement is a very important consideration for the safety of the
occupantsinthebuildingandforthemosteconomicaluseoftheappliance.
This water heater is not for use in manufactured (mobile) homes
or outdoor installation.
Whetherreplacing an old waterheater or putting thewaterheater in a
newlocation,thefollowing criticalpoints mustbe observed:
1. Selectalocation indoorsasclose aspracticaltotheventterminalor
locationtowhichthewaterheaterventpipingisgoingtobeconnected,
andas centralizedwith the waterpiping systemaspossible.
2. Selected location must provide adequate clearances for servicing
andproper operationof thewaterheater.
Installationofthewater heatermustbeaccomplishedinsucha manner
that if the tank or any connections should leak, the flow will not cause
damagetothestructure. For thisreason,it isnotadvisabletoinstallthe
waterheater inan attic orupper floor. Whensuch locations cannotbe

Thepanmustnotrestrict combustionair flow.
Water heater life depends upon water quality, water pressure and the
environment in which the water heater is installed. Water heaters are
sometimesinstalled inlocations whereleakagemay resultin property
damage, even with the use of a drain pan piped to a drain. However,
unanticipateddamagecanbereducedorpreventedbyaleakdetectoror

unless you provide air as shown in the “Locating The New Water
Heater”section. Never obstruct theflow of ventilation air. Ifyou have
anydoubtsorquestions atall, callyour gassupplier. Failureto provide
the proper amount of combustion air can result in a fire or explosion
andcause death, seriousbodilyinjury,or propertydamage.
FIGURE5.
Ifthiswaterheater willbeusedinbeautyshops,barber shops,cleaning
establishments,or self-servicelaundries withdry cleaningequipment,
it is imperative that the water heater or water heaters be installed so
thatcombustion andventilation airbetaken fromoutside these areas.
Propellants of aerosol sprays and volatile compounds, (cleaners,
chlorinebased chemicals,refrigerants, etc.)in additionto beinghighly
flammableinmany cases,will alsoreacttoformcorrosive hydrochloric
acid when exposed to the combustion products of the water heater.
Theresults can be hazardous, and also cause product failure.
INSULATION BLANKETS
Insulationblankets areavailableto thegeneralpublic for externaluse
ongas water heatersbutare not necessarywiththese products. The
purpose of an insulation blanket is to reduce the standby heat loss
encountered with storage tank heaters. Your water heater meets or
exceedsthe NationalAppliance Energy ConversationAct standards
withrespect to insulation and standby loss requirements, making an
insulationblanket unnecessary.
Should you choose to apply an insulation blanket to this heater, you
should follow these instructions (For identification of components
mentioned below, see Figure 1). Failure to follow these instructions
can restrict the air flow required for proper combustion, potentially
resultingin fire, asphyxiation, seriouspersonalinjury or death.
•Do not apply insulation to the top of the water heater, as this will
interfere with safe operation of the draft hood.
•Do not cover the outer door, thermostat or temperature& pressure
reliefvalve.
•Do not allow insulation to come within 2" (5.1 cm) of the floor to
preventblockage of combustion air flow to the burner.
•Do not cover the instruction manual. Keep it on the side of the
water heater or nearby for future reference.
•Doobtainnew warningand instructionlabels fromthemanufacturer
forplacement on theblanket directly overtheexisting labels.
•Do inspect the insulation blanket frequently to make certain it
doesnot sag, thereby obstructing combustion air flow.

The water within the water heater tank expands as it is heated and
increases the pressure of the water system. If the relieving point of the
water heater’s temperature-pressure relief valve is reached, the valve
will relieve the excess pressure. The temperature-pressure relief
valve is not intended for the constant relief of thermal expansion.
Thisisanunacceptable conditionandmust becorrected.
Itisrecommendedthat anydevicesinstalled whichcouldcreateaclosed
system have a by-pass and/or the system have an expansion tank to
relieve the pressure built by thermal expansion in the water system.
Expansion tanks are available for ordering through a local plumbing
contractor. Contactthe local watersupplier and/oraservice agencyfor
assistanceincontrollingthesesituations.
NOTE:To protectagainst untimelycorrosion of hot and cold water
fittings, it is strongly recommended that di-electric unions or

TEMPERATURE-PRESSURERELIEF VALVE
This heater is provided with a properly certified combination
temperature- pressure relief valve by the manufacturer.
Thevalve is certified by a nationally recognized testing laboratory that
maintains periodic inspection of production of listed equipment of
materialsas meeting therequirementsforRelief ValvesandAutomatic
GasShut-offDevicesforHot WaterSupplySystems,ANSIZ21.22•CSA
4.4,and thecode requirementsofASME.
Ifreplaced,the valvemust meettherequirementsoflocalcodes,but not
lessthan a combinationtemperatureand pressure reliefvalvecertified
asindicated in theabove paragraph.
Thevalve must bemarked with a maximumset pressure nottoexceed
the marked hydrostatic working pressure of the water heater
(150 psi =1,035kPa) and adischargecapacity not less thanthe water
heaterinput rate as shownonthe model rating plate.
For safe operation of the water heater, the relief valve must not be
removedfrom itsdesignated openingnor plugged.
Thetemperature-pressure reliefvalve mustbeinstalled directlyinto the
fitting of the water heater designed for the relief valve. Position the
valvedownward and provide tubing so thatanydischarge will exit only
within6 inches (15.2cm) above, orat any distancebelowthe structural
floor. Becertainthat nocontactis madewith anylive electricalpart. The
discharge opening must not be blocked or reduced in size under any
circumstances. Excessivelength, over30 feet (9.14m), or useof more
than four elbows can cause restriction and reduce the discharge
capacityofthevalve,seeFigures 10 or 14.
No valve or other obstruction is to be placed between the relief valve
andthe tank. Donot connecttubingdirectly todischarge drainunlessa
6"(15.2 cm) air gap isprovided. To preventbodily injury,hazard tolife,
orproperty damage,the reliefvalve mustbe allowedtodischarge water
inquantities shouldcircumstances demand. Ifthe discharge pipeis not
connectedto adrain orothersuitable means,the water flowmay cause
propertydamage.
TheDischargePipe:
•Shall not be smaller in size than the outlet pipe sizeof thevalve, or
haveany reducing couplings or other restrictions.
•Shall notbe pluggedor blocked.
•Shall be ofmaterial listed for hot waterdistribution.
•Shall be installed so as to allow complete drainage of both the
temperature-pressurerelief valve, and thedischarge pipe.
•Shall terminateat anadequatedrain.
•Shall not have any valvebetweenthe relief valve and tank.
Thetemperature-pressurereliefvalvemustbemanuallyoperatedatleast

injuryor property damage becausethewater may be extremelyhot.
If after manually operating the valve, it fails to completely reset and
continuesto releasewater,immediatelyclose thecoldwater inlettothe
water heater, follow the draining instructions, and replace the
temperature-pressurereliefvalve with a new one.

FILLINGTHE WATERHEATER
Never use this water heater unless it is completely full of water. To
preventdamage to the tank,thetankmust be filled withwater. Water
must flow from the hot water faucet before turning “ON” gas to the
water heater.
To fill the water heater with water:
1. Closethewaterheaterdrainvalvebyturningthehandletotheright
(clockwise). The drain valve is on the lower front of the water
heater.
2. Open the cold water supply valve to the water heater.
NOTE: The cold water supply valve must be left open when
the water heater is in use.
3. To insurecomplete fillingof thetank,allow airto exitby openingthe
nearest hot water faucet. Allow water to run until a constant flow
isobtained. This will let air out of the water heater and the piping.
4. Checkallwaterpipingandconnectionsforleaks. Repairasneeded.

VENTINGAND INSTALLATION
Plan the layout of the vent system from the vent termination to the
water heater considering all of the 90° and 45° elbows plus the
number of feet of pipe that would be needed to install the total vent
system. The water heater must be vented to the outdoors as
described in these instructions. DO NOT connect this water heater
to an existing vent or chimney. It must be vented separately from
all other appliances. Nonmetallic vent may be used if it has “Heat
DeflectionTemperature”(HDT@66 psi)or 455 kPa of at least 157°F
or69°C.Typicalnonmetallic ventmaterialsmeeting this requirement
are: PVC (Schedule 40, ASTM D-1785), Coex Cellular Core
(Schedule 40,ASTM F-441), CPVC (Schedule 40,ASTM D-2846),
ABS (Schedule 40, ASTM D-2661). The fittings, other than the
supplied VentTermination should be equivalent to the following:
PVC(Schedule40,DWV,ASTMD-2665), CPVC(Schedule 40,DWV,
ASTM F-438),ABS (Schedule 40 DWV,ASTM D-2661).
The cement used should be as recommended by the vent pipe
manufacturer.See theinstructionson pages 18 and19for the proper
methodof cuttingand cementingthe PVCpipe andfittings.

15
Theunitmay bevented horizontallythroughawallorverticallythrough
theroof. Pipe runs must beadequately supported along bothvertical
and horizontal runs as follows:
• ForSchedule40, 2"PVC,ABS,CoexCellular Corevent pipe:Every
3feet (0.9 m).
• ForSchedule40, 3"PVC,ABS,CoexCellular Corevent pipe:Every
3.5feet (1.1 m).
• ForSchedule40, 4"PVC,ABS,CoexCellular Corevent pipe:Every
4feet (1.2 m).
• ForSchedule 40, 2"CPVC vent pipe:Every 5 feet(1.5m).
• ForSchedule 40, 3"CPVC vent pipe:Every 6 feet(1.8m).
• ForSchedule 40,4"CPVC vent pipe:Every 6.5 feet(2.0 m).
It is imperative that the first hanger (or support) be located on the
horizontal run immediately adjacent to the first 90-degree elbow
from the vertical rise. Support method used should isolate the vent
pipe from the floor joists or other structural members to prevent
the transmission of noise and vibration. Do not support, pin, or
otherwise secure the venting system in a way that restricts the
normal thermal expansion and contraction of the chosen venting
material.
Ifthewaterheaterisbeinginstalledasareplacementforanexisting
power vented heater in pre-existing venting, a through inspection
of the existing venting system must be performed prior to any
installation work. Verify that the correct material as detailed above
hasbeenused,andthattheminimumormaximumventlengthsand
terminallocation as detailed inthismanual have been met. Carefully
inspect the entire venting system for any signs of cracks or
fractures,particularly at the joints between elbows and other fittings
and the straight runs of vent pipe. Check the system for signs of
sagging or other stresses in the joints as a result of misalignment
of any components in the system. If any of these conditions are
found, they must be corrected in accordance with the venting
instructions in this manual before completing the installation and
putting the water heater into service.
Except where instructed in this manual, the mixing of 2", 3" and 4"
vent pipe is NOTALLOWED. If 2" pipe is to be used, then a 2" to 3"
bell reducer is recommended. Figure 15 shows the recommended
location for the bell reducer. If the bell reducer is located at the
rubber boot on the blower assembly, then a short section of 3"
vent pipe needs to be installed in the rubber boot for proper
connection of the 2" to 3" bell reducer. That length can be of the
minimum length required for the connection.
If 4" pipe is to be used, then a 3" to 4" bell reducer is recommended.
Figure 15 shows the recommended location for the bell reducer. If
the bell reducer is located at the rubber boot on the blower
assembly, then a short section of 3" vent pipe needs to be installed
in the rubber boot for proper connection of the 3" to 4" bell reducer.
Thatlength canbe of theminimum length requiredfor theconnection.
The 40,000, 50,000, 55,000 and 62,500 BTU units are supplied
with a 2" Schedule 40 PVC 22.5° VentTerminal. If you decide to
vent with 3" or 4" pipe, a Schedule 40 DWV 45° Vent Terminal must
be used. For your convenience, we have included a screen for
both 3" and 4" VentTerminals.
The vent piping should be connected to the blower with a rubber
adapter and secured with hose clamps. The adapter and clamps
are provided with the heater.
Even the flue gas temperature leaving the blower is between 140°F
(69°C)and175°F(79°C),someinstallationswillhavewatercondensate
inthe ventpiping.If thisoccurs,then adequate meansof draining and
disposingof the condensateneedsto be made bythe installer.
CONDENSATE
Condensateformationdoesnotoccurinallinstallationsofpowervented

including, but not limited to ambient temperature and humidity of
installationlocation,ambienttemperatureandhumidityofventingspace,
ventdischargeand slope, and product usage. In certain conditions,
installationsinunconditionedspace orhavinglonghorizontal orvertical
ventruns may accumulate condensate. In theseconditions, the vent
pipe should be sloped downward away from the blower assembly
1/4"(6.4 mm)per five feet(1.5 m) ofpipe butnotmore than11/2" (3.8
cm)in the total vent length. Ifthevent piping is vented level or sloped
upwards away from the blower assembly, then adequate means for
draining and disposing of the condensate needs to be made by the
installer(if condensateis detected). Ifyou havecondensate,then a3/
8"drain hose can be connected to thebuilt-indrainport of the rubber
booton the blower assembly. Foryour convenience, the rubberboot
is supplied with a removable cap on the built-in drain port. Prior to
operatingthe water heater, makesurethe removable cap is installed
onthe drain port (if a drain hose is not needed).

plate as a template to mark the hole for the vent pipe to insert
throughthewall.BEWAREOFCONCEALEDWIRINGANDPIPING
INSIDE OFWALL.
2. If the VentTerminal is being installed on the outside of a finished
wall, it may be easier to mark both the inside and outside wall.
Alignthe holes bydrilling a holethroughthe center ofthe template
fromthe inside through to the outside. The template can nowbe
positionedon the outside wallusing the drilled hole asa centering
pointfor the template.
3. A) MASONRYSIDEWALLS
Chisel an opening approximately one half inch larger than the
markedcircle.
B) WOODENSIDEWALLS
Drill a pilot hole approximately one quarter inch outside of the
marked circle. This pilot hole is used as a starting point for a
saws-allor sabresaw blade. Cutaroundthe markedcircle staying
approximately onequarter inchoutsideof the line. (Thiswill allow
the vent pipe to easily slide through the opening. The resulting
gapwill becoveredup by thevent terminalcover plates.) Repeat
this step on inside wall if necessary.

VENTPIPE PREPARATION
1. INITIALPREPARATION
A. Make sure the solvent cement you are planning to use is
designedfor the specificapplication you are attempting.
B. Knowthephysicalandchemicalcharacteristicsandlimitations
ofthePVCandCPVCpipingmaterialsthatyouareabouttouse.
C. Know thereputation ofyourmanufacturer andtheir products.
D. Know your own qualifications or those of your contractor.
Thesolventwelding techniqueofjoiningPVCand CPVCpipe
isa specialized skill justas any other pipe fittingtechnique.
E. Closely supervisetheinstallation and inspectthe finished
jobbefore start-up.
F. Contact the manufacturer,supplier,or competent consulting
agency if you have any questions about the application or
installationofPVCand CPVCpipe.
G. Take the time and effort to do a professional job. Shortcuts
will only cause you problems and delays in start-up. By far,
the majority of failures in PVC and CPVC systems are the
resultof shortcuts and/orimproper joining techniques.
2. SELECTIONOFMATERIALS
• CuttingDevice -Saw or PipeCutter
• DeburringTool, Knife,File, orBeveling Machine(2" andabove)
• Brush- Pure Bristle
• Rag-Cotton(Not Synthetic)
• PrimerandCleaner
• SolventCement-PVCfor PVCComponentsandCPVC for CPVC
Components
• Containers -Metal orGlassto holdPrimer andCement. Select the
type of PVC or CPVC materials to be used on the basis of their
application with respect to chemical resistance, pressure rating,
temperaturecharacteristics, etc.
• InsertionTool -Helpfulfor largerdiameter pipeand fittings6 inches
(15.2cm) and above.
PRIMER
Itis recommendedthat Tetrahydrofuran (THF)be used topreparethe
surfaces of pipe and fittings for solvent welding. Do not use water,
rags, gasoline or any other substitutes for cleaning PVC or CPVC
surfaces.Achemical cleaner suchasMEK may be used.
CEMENT
Thecement shouldbea bodiedcementof approximately500to 1600
centipoiseviscositycontaining 10-20%(byweight)virginPVC material
solvated with tetrahydrofuran (THF). Small quantities of dimethyl
formamide(DMF)maybeincludedtoactasaretardingagenttoextend
curingtime. Selectthe propercement; Schedule40 cementshould be
usedforSchedule40pipe.Neveruseall-purposecements,commercial
glues and adhesives or ABS cement to join PVC or CPVC pipe and
fittings.
APPLICATORS
Select a suitable pure bristle type paint brush. Use a proper width
brush or roller to apply the primer and cement (see chart below).
Speedy application of cement is important due to its fast drying
characteristics. IMPORTANTNOTE:Adaubertype applicator should
only be used on pipe sizes 2" and below. For larger diameter pipe, a
brushor roller must be used.

3.MAKINGTHEJOINT
A. Cutting
Pipemust be squarely cut toallow for the proper interfacingofthe
pipeend and the fitting socket bottom. This can be accomplished
with a miter box saw or wheel type cutter. Wheel type cutters are
notgenerallyrecommendedforlargerdiameters sincethey tendto
flare the corner of the pipe end. If this type of cutter is used, the
flareon theend must becompletely removed.
NOTE:Powersaws shouldbe specificallydesigned tocut plasticpipe.

B. Deburring
Useaknife,plasticpipedeburringtool,orfiletoremoveburrsfromtheend
ofsmalldiameterpipe. Besuretoremoveallburrsfromaroundtheinside
aswellastheoutsideofthepipe. Aslightchamfer(bevel)ofabout10°-
15°shouldbeaddedtotheendtopermiteasierinsertionofthepipeinto
theendofthefitting. Failuretochamfertheedgeofthepipemayremove
cementfromthefittingsocket,causingthejointtoleak.
STEPB
C. Test dry fit of the joint
Tapered fittingsocketsare designedso thatan interfacedfit should
occurwhen the pipeisinserted about 1/3to2/3 of the wayinto the
socket. Occasionally, when pipe fitting dimensions are at the
toleranceextremes, it will be possible tofullyinsert dry pipe to the
bottomofthefitting socket. Whenthishappens,asufficientquantity
ofcementmustbeappliedtothejointtofillthegapbetweenthepipe
andfitting. Thegapmustbefilled toobtain astrong, leak-freejoint.
D. Inspection, cleaning, priming
Visuallyinspecttheinsideofthepipeandfittingsocketsandremove
all dirt, grease or moisture with a clean dry rag. If wiping fails to
clean the surfaces, a chemical cleaner must be used. Check for
possibledamage suchas splitsorcracks andreplaceif necessary.
Depth-of-entry
Markingthedepthofentryisawaytocheckifthepipehasreached
thebottom of thefittingsocket in StepF. Measure the fittingdepth
and mark this distance on the pipe O.D. You may want to add
several inches to the distance and make a second mark as the
primerand cement will most likelydestroy your first one.
Applyprimer to the surface of the pipe and fitting socket with a natural
bristlebrush.ThisprocesssoftensandpreparesthePVCorCPVCfor

• Applya light coat of cement evenly around the inside ofthe
fittingsocket. Avoid puddling.
• Applya second coat of cement to the pipe end.

F. Joint assembly
Working quickly, insert the pipe into the fitting socket bottom and
givethe pipeor fittinga 1/4 turnto evenlydistribute the cement.Do
notcontinuetorotatethepipe afterit hashit thebottom ofthe fitting

togetherfor about 15 seconds.
STEPF
G. Cleanup and joint movement
Removeall excess cement from around thepipeand fitting with a
drycotton rag. This must be done while the cement is stillsoft.
Thejoint should not bedisturbed immediately after the cementing
procedure,and sufficient timeshouldbe allowed forpropercuring
ofthejoint.Exactdryingtimeisdifficulttopredictbecauseitdepends
