LOCATING THE NEW WATER HEATER
IMPORTANT SAFETY INSTRUCTIONS
Facts To Consider About The Locaon
Carefully choose an indoor locaon for the new water heater,
because the placement is very important consideraon for
the safety of the occupants in the building and for the most
economical use of the appliance.
Whether replacing an old water heater or pung the water
heater in a new locaon, the following crical points must be
observed:
1. Select a locaon as close as praccal or centralized to the
point of use. The water heater should be located in an area
not subject to freezing temperatures.
2. Selected locaon must provides adequate clearances for
removing the front cover in order to service parts such as the
thermostat, element, temperature sensor, anode, and high
limit reset. Adequate clearance for servicing this appliance
should be considered before installaon, such as operang
the relief valve, etc.
3. The water heater should be located so it is not subject to
physical damage by moving vehicles or area ooding.
4. The selected wall or cabinet must be capable of supporng
at least two mes the weight of the water heater when lled
with water (7 7Ibs).
5. The water heater must be installed in a vercal posion with
water inlet and outlet connecons facing upwards and easily
accessible.
Installaon of the water heater must be accomplished in such a
manner that if the tank or any connecons should leak, the ow
will not cause damage to the structure. For this reason, it is not
advisable to install the water heater in an ac or upper oor.
When such locaons cannot be avoided, a suitable drain pan
should be installed under the water heater. Drain pans are
available from your local plumbing contractor. Such a drain pan
must have a minimum length and width of at least 2 inches (51
mm) greater than the water heater dimensions and must be piped
to an adequate drain.
Water heater life depends upon water quality, water pressure,
water usage, water temperature, and the environment in which
the water heater is installed. Water heaters are somemes
installed in locaons where leakage may result in property
damage, even with the use of a drain pan piped to a drain.
However, unancipated damage can be reduced or prevented
by a leak detector or water shut-o device used in conjuncon
with a piped drain pan. These devices are available from some
plumbing supply wholesalers and retailers, and detect and react
to leakage in various ways:
• Sensors mounted in the drain pan that trigger an alarm
or turn o the incoming water to the water heater when
leakage is detected.
• Sensors mounted in the drain pan that turn o the water
supply to the enre home when water is detected in the
drain pan.
• Water supply shut-o devices that acvate based on the
water pressure dierenal between the cold water and hot
water pipes connected to the water heater.
INSULATION BLANKETS
Insulaon blankets are available to the general public for external
use on electric water heaters but are not necessary with this
product. The purpose of an insulaon blanket is to reduce the
standby heat loss encountered with storage tank heaters.
Should you choose to apply an insulaon blanket to this heater,
you should follow these instrucons below. Failure to follow
these instrucons can result in re, serious personal injury, or
death.
Do not cover the temperature and pressure relief (T&P) valve
with an insulaon blanket.
Do not cover the instrucon manual. Keep it on the side of the
water heater or nearby for future reference.
Do obtain new warning and instrucon labels for placement on
the blanket directly over the exisng labels.
1. READ ALL INSTRUCTIONS BEFORE USING THIS WATER
HEATER.
2. This water heater mush be grounded. Connect only
to properly grounded outlet. See GROUNDING
INSTRUCTIONS found in the WIRING secon of
this manual.
3. Install or locate this water heart only in accordance with
theprovided installaon instrucons.
4. Use this water heater for its intended use as described in this
manual.
5. Do not use an extension cord set with this water heater.
If no receptacle is available adjacent to the water heater,
contact a qualied electrician to have one properly installed.
6. As with any appliance, close supervision is necessary when
used by children.
7. Do not operate this water heater if it has a damaged cord or
plug, if it is not working properly, or if it has been damaged
or dropped.
8. This water heater should be serviced only by qualied
service personnel. Contact nearest authorized service facility
for examinaon, repair, or adjustment.

DANGER
Fire Hazard/Electrical Shock Hazard
When using electrical appliances, basic safety
precauons to reduce the risk of re, electric
shock, or injury to persons should be followed.

MOUNTING
MOUNTING-DRYWALL (HOLLOW WALL)
1. The selected wall or cabinet must be capable of supporng
double the weight of the unit when completely full of
water(77Ibs).
2. The installaon area must provide adequate clearances for
removal of the front panel and servicing the unit.
3. Locate the wall studs in the area where the unit is to be
mounted.
4. Cut two secons of 1/2 inch plywood or equivalent material
3 inches in height. The length of each secon should be
sucient to span the width of the wall studs. See Figure 3A.
5. Use appropriately sized nails or wood screws to aach the
two wall supports to the wall as show in Figure 3A.
6. Drill two 13/32 inch holes in the upper wall support NOTE:
The holes must be level.
7. Insert the hollow wall anchors into the drilled holes. Place
the wall bracket over the anchors and screw the two Phillips
head screws down ght against the bracket.
MOUNTING-MASONRY WALL (SOLID WALL)
1. The selected wall or cabinet must be capable of supporng
double the weight of the unit when completely full of
water(77Ibs ).
2. The installaon area must provide adequate clearances for
removal of the front panel and servicing the unit.
3. Drill two 13/32 inch holes in the masonry wall. NOTE: The
holes must be level and at least 3-1 /2 inches deep.
4. Insert the masonry wall anchors into the drilled holes. Place
the wall bracket over the anchors and screw the two Phillips
head screws ght against the bracket.
WATER PIPING
HOTTER WATER CAN SCALD:
Water heaters are intended to produce hot water. Water heated
to a temperature which will sasfy space heang, clothes
washing, dish washing, cleaning and other sanizing needs can
scald and permanently injury you upon contact. Some people are
more likely to be permanently injured by hot water than others.
These include the elderly, children, the inrm, or physically/
mentally disabled. If anyone using hot water in your home ts
into one of these groups or if there is a local code or state law
requiring certain temperature water at the hot water tap, then
you must take special precauons. In addion to using the lowest
possible temperature seng that sases your hot water needs,
a means such as a mixing valve should be used at the hot water
taps used by these people or at the water heater. Valves for
reducing point of use temperature by mixing cold and hot water
are also available.
Consult a Qualied Installer or Service Agency. Follow
manufacturer's instrucons for installaon of the valves.
Before changing the factory seng on the thermostat, read the
"Temperature Regulaon" secon in this manual.

DANGER
Water temperature over 125°F
(52°C) can cause severe burns
instantly resulng in severe injury
or death.
Children, the elderly, and the
physically or mentally disabled are
at highest risk for scald injury.
Feel water before bathing or
showering.
Temperature liming valves are
available. Read this instrucon
manual for safe temperature seng.

This water heater shall not be connected to any heang systems
or components used with a non potable water heang appliance.
Toxic chemicals, such as those used for boiler treatment shall not
be introduced into this system.
Water supply system may, because of such events as high line
pressure, frequent cut-os, the eects of water hammer among
others, have installed devices such as pressure reducing valves,
check valves, back ow preventers, etc. to control these types of
problems. When these devices are not equipped with an internal
by-pass, and no other measures are taken, the devices cause the
water system to be closed. As water is heated, it expands(thermal
expansion) and closed systems do not allow for the expansion of
heated water.
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 limited for the constant
relief of thermal expansion. This is an unacceptable condion and
must be corrected.
It is recommended that any devices installed which could create
a closed system have a by-pass and/or the system have an
expansion tank or device to relieve the pressure built by thermal
expansion in the water system. Expansion tanks are available
for ordering through a local plumbing contractor. Contact the
local water supplier and/or a service agency for assistance in
controlling these situaons.
NOTE: To protect against unmely corrosion of hot and cold
water ngs, it is strongly recommended that di electric unions
or couplings be installed on this water heater when connected
to copper pipe.
Figure 4 shows the typical aachment of the water piping to the
water heater. The water heater is equipped with 1/2 inch NPT
water connecons.
NOTE: If using copper tubing, older tubing to an adapter before
aaching the adapter to the cold water inlet connecon. Do not
solder that cold water supply line directly to the cold water inlet,
it will harm the dip tube and damage the tank.
WATER PIPING PRESSURE TEST
This secon is only for the manufacturer installing the water
heater when the installaon is to comply with H.U.D. Standards.
When tesng the water ways, H.U.D. Standards state:
"Water distribuon system: All water piping in the water
distribuon system shall be subjected to a pressure test. The test
shall be made by subjecng the system to air or water at 1 00psi
for 15 minutes without loss of pressure. When air pressure is
used, the water heater shall not be connected during the test."
