5. Choosing Installation Site
* Locatetheapplianceinanareawhereleakagefromtheunitorconnectionswillnotresultindamage
to the area adjacent to the appliance or to the lower oors of the structure. When such locations
cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed
under the appliance. The pan must not restrict combustion air ow.
•Locate the vent terminal so that there are no obstacles around the termination and so that exhaust
can't accumulate. Do not enclose the termination with corrugated metal or other materials.
•Avoidplaceswhereresarecommon,suchasthosewheregasoline,
benzene and adhesives are handled, or places in which corrosive gases
(ammonia, chlorine, sulfur, ethylene compounds, acids) are present.
 Usingtheincorrectvoltagemayresultinreorcracking.
•Avoidinstallationinplaceswheredustordebriswillaccumulate.
Dustmayblocktheair-supplyopening,causingtheperformanceofthe
device fan to drop and incomplete combustion to occur as a result.
•Avoidinstallationinplaceswherespecialchemicalagents
(e.g., hair spray or spray detergent) are used.
Ignition failures and malfunction may occur as a result.
•CarbonMonoxidePoisoningHazard.Donotinstallthiswaterheaterina
recreational vehicle or on a boat.
•Thewaterheaterisdesignedforindoorinstallationonly.Neverinstallit
outdoors or in a bathroom, it may be damaged or a re may be caused.
•Consultwiththecustomerconcerningthelocationofinstallation.
•Install the water heater in an area that allows for the proper clearances
to combustible and noncombustible construction. Consult the rating
plate on the appliance for proper clearances.
•Donotinstallthewaterheaterinaplacewhereitmaybethreatenedby
falling objects, such as under shelves.
•Thewaterheatermustbeinstalledinaplacewheresupplyandexhaust
pipes can be installed as directed.
•Donotinstallthewaterheaterwheretheexhaustwillblowonouter
walls or material not resistant to heat. Also consider the surrounding
trees and animals.
The heat and moisture from the water heater may cause discoloration
of walls and resinous materials, or corrosion of aluminum materials.

Filling the condensate trap before vent pipe installation.
DANGER
Priortoinitialstartup,makesurethatyoullthecondensatetrapwithwater.
This is to prevent dangerous exhaust gases from entering the building.

Please follow one of the procedures described below to ensure that the condensate trap is lled with water.
1)Fillthecondensatetrapbypouringapprox.30oz.(850ml)ofwaterintotheexhaustaccessoryonthetop
of the appliance as illustrated below.
Or, if the vent pipe has already been installed:
2)Afterinstallingthedrainpipe,makesurethattheareaaroundtheapplianceiswellventilated;opena
window or a door if necessary.
Then, operate the unit and verify that condensate is coming out of the drain pipe.
(During normal use of the water heater, condensate will begin to discharge from the drain pipe within
15minutesofuse.However,dependingontheseasonand/orinstallationsiteconditions,itmaytakelonger.)
Note:ThecondensatedischargedfromthewaterheaterhasapHlevelofapproximately2-3.

Note: Do Not Use Cellular Foam Core Pipe
PVC/CPVC Installation Instructions
• Use only solid PVC or CPVC schedule 40 pipe. Cellular foam core piping is not allowed.
•
• Follow all general venting guidelines as outlined on this page.
• The pipe shall be installed so that the rst 3’ (0.9m) of pipe from the appliance ue outlet is readily
accessible for visual inspection.
• When preparing and assembling the pipe, follow instructions as provided by the pipe
manufacturer. In general, the following practices must be observed:
o Squarely cut all pieces of pipe.
o Remove all burs and debris from joints and ttings.
o All joints must be properly cleaned, primed, and cemented. Use only cement and primer
approved for use with the pipe material as outlined in the above table.
•
• PVC or CPVC pipe has been approved for use on this appliance with zero clearance to combustibles.
All piping must be fully supported. Use pipe hangers at a minimum of 3’ (0.9m) intervals. Do not use
the water heater to support the vent piping.
3" or 4" schedule 80 pipe may also be used on this appliance, however the BTUH input of the
appliance will be reduced by up to 5%.

Venting With PVC or CPVC
This appliance can be vented with non cellular core plastic pipe materials as specied in the below table.
•
• A bird screen must be installed on the vent terminations to prevent debris or animals from entering the
piping. These screens are not supplied with the water heater and must be purchased separately
(part #VT4-PVCS, use part #VT3-PVCS when using 3" (75mm) PVC or CPVC).
When attaching the piping to the water heater, use the appropriate primer and cement to ensure a
proper seal.

WARNING
If the distance between the air inlet and exhaust vent terminations is too short, the water heater
will draw in the exhaust gases through the intake. There is a risk of inadequate combustion air
for the water heater, increasing Carbon Monoxide (CO) emissions and noise due to vibration.
•Termination elbows must be oriented vertically, pointing directly downward. Attempts to prevent
exhaust air from entering the air inlet by angling termination elbows in directions other than
directly downward will increase the risk of freezing.
•Reversing the air intake and exhaust pipes is not allowed.
Carbon Monoxide (CO) emissions and noise due to vibration will increase.

As illustrated on the left, make sure to keep a distance of 3' (0.9m)
or wider between the intake and exhaust when installing the vent piping.
The PVT-HL termination may be used in place of elbows as the
horizontal vent terminations. It is not necessary touse bird screens
with the PVT-HL termination.
Terminate at least 12" (300mm) above grade or above snow line.
Terminate at least 7' (2.1m) above a public walkway, 6' (1.8m)

from any other building opening, gas utility meter, service regulator etc.
Terminate at least 3' (0.9m) above any forced air inlet within
10' (3m) , 1' (0.3m) below, 1' (0.3m) horizontally from or 1' (0.3m)
above any door, window, or gravity air inlet into any building per
National Fuel Gas Code ANSI Z223.1/NFPA 54.
Slope the horizontal vent 1/4" upwards for every 12" (300mm)
toward the termination.
Use a condensation drain if necessary.
In the Commonwealth of Massachusetts a carbon monoxide detector
is required for all side wall horizontally vented gas fuel equipment.
Please refer to Technical Bulletin TB 010606 for full installation
instructions.
As illustrated on the left, make sure to keep a distance
of 3' (0.9m) or wider between the intake and exhaust
when installing the vent piping.
Terminate at least 6' (1.8m) from the combustion air
intake of any appliance, and 3' (0.9m) from any other
building opening, gas utility meter, service regulator etc.
Enclose exterior vent systems below the roof line to limit
condensation and protect against mechanical failure.
When the vent penetrates a oor or ceiling and is not
running in a re rated shaft, a restop and support is
required.
When the vent termination is located not less than
8' (2.4m) from a vertical wall or similar obstruction,
terminate above the roof at least 2' (0.6m), but not
more than 6' (1.87m), in accordance with the National
Fuel Gas Code ANSI Z223.1/NFPA 54.
Provide vertical support every 3' (0.9m) or as required
by the vent pipe manufacturer's instructions.
A short horizontal section is recommended to prevent
debris from falling into the water heater.
When using a horizontal section, slope the horizontal
vent 1/4” upwards for every 12” (300mm) toward the
termination to drain condensate.
**1' minimum recommended,
but not required.
*
Not supplied with water heater,

When choosing intake and exhaust terminations, you must use the
same type of elbow (i.e. both 45° elbows, or both 90° elbows).
This will help with proper combustion by putting both terminations in
the same pressure zone.
