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


eople are more likely to be permanently injured by
ot 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 pre­

cautions. In addition to using the lowest possible

temperature setting that satisfies your hot water

needs, a means sucn as a mixing valve, should be

used at the hot water taps used by these people or

at the water heater. Mixing valves are available at

plumbing supply or hardware stores. Follow manu­

facturers instructions for installation of the valves.

Before changing the factory setting on the thermo­

stat, read the "Temperature Regulation" section in
this manual.


INSULATING JACKETS: When installing an external

water heater insulation jacket on an electric water

•DO NOT cover the temperature-pressure relief


• DO NOT put insulation over the access covers or

any access areas.

• DO NOT cover or remove operating instructions,

and safety related warning labels and materials
affixed to the water heater.


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.


At the time of manufacture this water heater was pro­
vided with a combination temperature-pressures relief

valve certified by a nationally recognizeci testing labora­
tory that maintains periodic inspection of production of

listed equipment or materials, as meeting the require­
ments 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 require­

ments of local codes, but not less than a combination

temperature and pressure relief valve certified as meet­

ing the requirements for Relief Valves and Automatic

Gas Shutoff Devices for Hot Water Supply Systems, ANSI
Z21.22 by a nationally recognized testing laboratory

that maintains periodic inspection of production of list­

ed 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 Ibs./sq. in.) 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 3415 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
different 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


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 with­

in 6 inches above, or at any distance below the struc­

tural floor. Be certain 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 provid­
ed. To prevent bodily injury, hazard to life, or property

damage, the relief valve must be allowed to discharge

water in quantities should circumstances demand. If the

discharge pipe is not connected to a drain or other suit­

able means, the water flow may cause property dam-

The Discharge Pipe;

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

the valve, or have any reducing couplings or other

• 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
