General Safety

WARNING

Improper installation, adjustment, alteration, service or mainte-

nance can cause DEATH, SERIOUS BODILY INJURY, OR

PROPERTY DAMAGE. Refer to this manual for assistance or

consult the local electric utility for further assistance.

WARNING

At the time of manufacture this water heater was provid-

ed with a combination temperature-pressure relief valve

certified by a nationally recognized testing laboratory that

maintains periodic inspection of production of listed

equipment or materials, as meeting the requirements for

Relief Valves and Automatic Gas Shutoff Devices for Hot

Water Supply Systems, and the latest edition of ANSI

Z21.22 and the code requirements of ASME. If replaced,

the valve must meet the requirements of local codes, but

not less than a combination temperature and pressure

relief valve certified as meeting the requirements for

Relief Valves and Automatic Gas Shutoff Devices for Hot

Water Supply Systems, ANSI Z21.22 by a nationally rec-

ognized testing laboratory that maintains periodic inspec-

tion of production of listed equipment or materials.

The valve must be marked with a maximum set pressure

not to exceed the marked hydrostatic working pressure of

the water heater (150 lbs. p.s.i.) and a discharge capacity

not less than the water heater input rate as shown on the

model rating plate. (Electric heaters - watts divided by

1000 x 3412 equal BTU/Hr. rate.)

Your local jurisdictional authority, while mandating the

use of a temperature-pressure relief valve complying with

ANSI Z21.22 and ASME, may require a valve model differ-

ent from the one furnished with the water heater.

Compliance with such local requirements must be satis-

fied by the installer or end user of the water heater with a

locally prescribed temperature-pressure relief valve

installed in the designated opening in the water heater in

place of the factory furnished valve.

For safe operation of the water heater, the relief valve must

not be removed from it’s designated opening or plugged.

The temperature-pressure relief valve must be installed

directly into the fitting of the water heater designated for

the relief valve. Position the valve downward and provide

tubing so that any discharge will exit only within 6 inches

above, or at any distance below the structural floor. Be cer-

tain that no contact is made with any live electrical part.

The discharge opening must not be blocked or reduced in

size under any circumstances. Excessive length, over 30

feet, or use of more than four elbows can cause restriction

and reduce the discharge capacity of the valve.

No valve or other obstruction is to be placed between the

relief valve and the tank. Do not connect tubing directly

to discharge drain unless a 6

″″

air gap is provided. To pre-

vent bodily injury, hazard to life, or property damage, the

relief valve must be allowed to discharge water in quanti-

ties should circumstances demand. If the discharge pipe is

not connected to a drain or other suitable means, the

water flow may cause property damage.

The Discharge Pipe:

—Must not be smaller in size than the outlet pipe size of the

valve, or have any reducing couplings or other restriction.

—Must not be plugged or blocked.

—Must be of material listed for hot water distribution.

—Must be installed so as to allow complete drainage of both

the temperature-pressure relief valve, and the discharge

pipe.

—Must terminate at an adequate drain.

—Must not have any valve between the relief valve and tank.

WARNING

HAZARD OF ELECTRICAL SHOCK! Before removing any

access panels or servicing the water heater, make sure the

electrical supply to the water heater is turned “OFF”.

Failure to do this could result in DEATH, SERIOUS BODI-

LY INJURY, OR PROPERTY DAMAGE.

WARNING

HOTTER WATER CAN SCALD: Water heaters are intended

to produce hot water. Water heated to a temperature

which will satisfy clothes washing, dish washing, and other

sanitizing needs can scald and permanently injure you

upon contact. Some people are more likely to be perma-

nently injured by hot water than others. These include the

elderly, children, the infirm, or physically/mentally handi-

capped. 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 water tap,

then you must take special precautions. In addition to using

the lowest possible temperature setting that satisfies your

hot water needs, some type of tempering device, such as a

mixing valve, should be used at the hot water taps used by

these people or at the water heater. Mixing valves are avail-

able at plumbing supply or hardware stores. Follow manu-

facturers instructions for installation of the valves, Before

changing the factory setting of the thermostat, read the

“Temperature Regulation” section in this manual.

WARNING

WATER HEATERS EQUIPPED FOR ONE VOLTAGE ONLY:

This water heater is equipped for one type voltage only.

Check the rating plate near the bottom access panel for

the correct voltage. DO NOT use this water heater with

any voltage other than the one shown on the model rating

plate. Failure to use the correct voltage can cause prob-

lems which can result in DEATH, SERIOUS BODILY

INJURY, OR PROPERTY DAMAGE. If you have any ques-

tions or doubts consult your electric company.

WARNING

INSULATING JACKETS: When installing an external water

heater insulation jacket on an electric water heater:

a. DO NOT cover the temperature-pressure relief valve.

b. DO NOT put insulation over the access covers or any

access areas.

c. DO NOT cover or remove operating instructions, and

safety related warning labels and materials affixed to

the water heater.

WARNING

Do not use this appliance if any part of it has been under

water. An electrical short or malfunction could occur. The

water heater should be replaced.

CAUTION

WATER HEATERS EVENTUALLY LEAK: Installation of the

water heater should be accomplished in such a manner

that if the tank or any connections should leak, the flow

of water will not cause damage to the structure. For this

reason, it is not advisable to install the water heater in an

attic or upper floor. When such locations cannot be avoid-

ed, a suitable drain pan should be installed under the

water heater. Drain pans are available at your local hard-

ware store. Such a drain pan must be piped to an ade-

quate drain. Under no circumstances is the manufacturer

to be held liable for any water damage in connection with

this water heater.
