GENERAL INFORMATION

The design of this electric water has been listed with Underwriters’

Laboratories, Inc. (UL) as complying with UL standard UL1453.

This water heater must be installed in accordance with local codes. In the

absence of local codes, install this water heater in accordance with the N.E.C.

Reference Book (latest edition).

The warranty for this water heater is in effect only when the water heater is

installed, adjusted and operated in accordance with these Installation and

Operating Instructions. The manufacturer will not be held liable for damage

resulting from alteration and/or failure to comply with these instructions.

This water heater has been designed and listed for the purpose of heating

potable water. The installation and use of this water heater for any purpose

other than the heating of potable water may cause damage to the water heater

and create a hazardous condition and nullify the warranty.

Do not use this appliance if any part has been under water. Immediately call a

qualified service technician to inspect the appliance and to replace any part of

the control system and/or any gas control, which has been under water.

Depending upon individual circumstances, it may be necessary to replace the

entire water heater.

Make sure that the rating plate on the water heater is referenced for certainty

that the correct voltage is being supplied to the water heater.

General Information continued-

A sacrificial anode(s) is used to extend tank life. Removal of any anode, for

any reason, will nullify the warranty. In areas where water is unusually active,

an odor may occur at the hot water faucet due to a reaction between the

sacrificial anode and impurities in the water. If this should happen, an

alternative anode(s) may be purchased from the supplier that installed this

water heater. This will minimize the odor while protecting the tank.

Additionally, the water heater should be flushed with appropriate dissolvers to

eliminate any bacteria.

IMPORTANT

Before proceeding, please inspect the water heater and its components for

possible damage. DO NOT install any damaged components. If damage is

evident, please contact the supplier where the water heater was purchased or

the manufacturer listed on the rating plate for replacement parts.

INSTALLATION

Locating The Water Heater

Thiswater heater must NOT be installed in any location where gasoline

or flammable vapors are likely to be present, unless the installation is

such to eliminate the ignition of gasoline or flammable vapors.

The location for the installation of this water heater is of utmost importance.

Before installing this water heater, consult the installation section of these

instructions. After reading these installation and operating instructions, select

a location for the water heater where the floor is level and is easily accessible

to a power supply and water connections. It is recommended that the water

heater be located near the center of greatest hot water usage to prevent heat

loss through the pipes. DO NOT locate the water heater where water

lines could be subjected to freezing temperatures. Locate the water

heater so that access panels and drain valves are accessible.

Water heater corrosion and component failure can be caused by the heating

and breakdown of airborne chemical vapors. Examples of some typical

compounds that are potentially corrosive are: spray can propellants, cleaning

solvents, refrigerator and air conditioning refrigerants, swimming pool

chemicals, calcium or sodium chloride, waxes and process chemicals. These

materials are corrosive at very low concentration levels with little or no odor to

reveal their presence. NOTE: DAMAGE TO THE WATER HEATER CAUSED

BY EXPOSURE TO CORROSIVE VAPORS IS NOT COVERED BY THE

WARRANTY. DO NOT OPERATE THE WATER HEATER IF EXPOSURE

HAS OR WILL OCCUR. DO NOT STORE ANY POTENTIALLY CORROSIVE

COMPOUNDS IN THE VICINITY OF THE WATER HEATER.

Locating The Water Heater continued-

This water heater must be located in an area where leakage of the tank or

water line connections and the combination temperature and pressure relief

WARNING

Water heaters are heat-producing appliances. To avoid damage or injury,

there must be no materials stored against the water heater and proper care

must be taken to avoid unnecessary contact (especially by children) with the

water heater. UNDER NO CIRCUMSTANCES SHALL FLAMMABLE

MATERIALS, SUCH AS GASOLINE OR PAINT THINNER BE USED OR

STORED IN THE VICINITY OF THIS WATER HEATER OR ANY LOCATION

FROM WHICH FUMES COULD REACH THE WATER HEATER.

valve will not result in damage to the area adjacent to the water heater or to

lower floors of the structure. When such locations cannot be avoided, a

suitable drain pan must be installed under the water heater. The drain pan

must be no greater than 1 1/2 in. (3.8 cm) deep and have a minimum length

and width of at least 4 in. (10.2 cm) measured from the jacket of the water

heater. The drain pan, as described above, can be purchased from your

plumbing professional. The drain pan must be piped to an adequate drain.

The piping must be pitched for proper drainage.

Water Connections

NOTE: BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE

MAIN WATER SUPPLY VALVE.

After shutting the main water supply valve, open a faucet to relieve the water

line pressure to prevent any water from leaking out of the pipes while making

the water connections to the water heater. After the pressure has been

relieved, close the faucet. The cold water inlet line connects to the inlet nipple

at the base of the water heater. The hot water outlet line connects to the

nipple on top of the water heater. The fittings at the cold water inlet and hot

water outlet are dielectric waterway fittings with tapered male threads. Make

the proper plumbing connections between the water heater and the plumbing

system in the structure. Install a shut-off valve in the cold water supply line.

If this water heater is installed in a closed water supply system, such as one

having a back-flow preventer in the cold water supply, provisions shall be made

to control thermal expansion. DO NOT operate this water heater in a closed

system without provisions for controlling thermal expansion. Your water

supplier or local plumbing inspector should be contacted on how to control this

situation.

After installation of the water lines, open the main water supply valve and fill

the water heater. While the water heater is filling, open several hot water

faucets to allow air to escape from the water system. After a steady stream of

water flows from the faucets, close them and check all water connections for

possible leaks. NEVER OPERATE THE WATER HEATER WITHOUT FIRST

BEING CERTAIN IT IS FILLED WITH WATER.

Water Connections continued-

CAUTION

If sweat fittings are to be used, DO NOT apply heat to the nipples on top of

the water heater. Sweat the tubing to the adapter before fitting the adapter

to the water connections. It is imperative that heat is not applied to the

nipples containing a plastic liner.

IMPORTANT

FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED TEMPERATURE-

PRESSURE RELIEF VALVE WILL RELEASE THE MANUFACTURER

FROM ANY CLAIM, WHICH MIGHT RESULT FROM EXCESSIVE

TEMPERATURE AND PRESSURES.

Water Connections continued-

WARNING

For protection against excessive temperatures and pressure, install

temperature and pressure protective equipment required by local codes, but

not less than a combination temperature and 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, ANSI Z21.22, and the Standard CAN1-4.4 Temperature, Pressure,

Temperature and Pressure Relief Valves and Vacuum Relief Valves. The

combination temperature and pressure relief valve must be marked with a

maximum set pressure, not to exceed the maximum working pressure of the

water heater. The combination temperature and pressure relief valve shall

also have an hourly rated temperature steam BTU discharge capacity not

less than the hourly input rating of the water heater.

Install the combination temperature and pressure relief valve into the opening

provided and marked for this purpose on the water heater

Note: Some models may already be equipped or supplied with a

combination temperature and pressure relief valve. Verify that the

combination temperature and pressure relief valve complies with local codes.

If the combination temperature and pressure relief valve does not comply

with local codes, replace it with one that does. Follow the installation

instructions above on this page.

Install a discharge line so that water discharged from the combination

temperature and pressure relief valve will exit within six (6) inches (15.3 cm)

above, or any distance below the structural floor and cannot contact any live

electrical part. The discharge line is to be installed to allow for complete

drainage of both the temperature and pressure relief valve and the discharge

line. The discharge opening must not be subjected to blockage or freezing.

DO NOT thread, plug or cap the discharge line. It is recommended that a

minimum of four (4) inches (10.2 cm) be provided on the side of the water

heater for servicing and maintenance of the combination temperature and

pressure relief valve.

Do not place a valve between the combination temperature and pressure

relief valve and the tank.

WARNING

Hydrogen gas can be produced in a hot water system served by this

water heater that has not been used for a long period of time

(generally two weeks or more). Hydrogen gas is extremely

flammable. To reduce the risk of injury under these conditions, it is

recommended that the hot water faucet be opened for several

minutes at the kitchen sink before using any electrical appliance

connected to the hot water system. If hydrogen is present, there will

probably be an unusual sound such as air escaping through the pipe

as the water begins to flow. There should be no smoking or open

flame near the faucet at the time it is open.

CAUTION

INCREASING THE THERMOSTAT SETTING ABOVE THE PRESET

TEMPERATURE MAY CAUSE SEVERE BURNS AND CONSUME

EXCESSIVE ENERGY. HOTTER WATER INCREASES THE RISK OF

SCALD INJURY.
