GENERAL INFORMATION

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

absence of local codes, install this water heater in accordance with national

or regional requirements.

The best efficiency and longest product life is obtained 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.

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 which has been under water. Depending upon

individual circumstances, it may be necessary to replace the entire water

heater.

Make sure that the voltage being supplied to the water heater is according to

the voltage printed on the product rating plate.

CAUTION

Incorrect operation of this appliance may create a hazard to life and

property and may impair and shorten heater life.

DANGER

Do not store or use gasoline or other flammable, combustible or

corrosive vapors and liquids in the vicinity of this or any other

appliance.

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.

General Information continued-

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

any reason, will shorten the products useful life. 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.

INSTALLATION

Locating The Water Heater

This water 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 where this water heater is to be installed will be 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

where the power supply and water connections are easily accessible. It is

recommended that the water heater be located near the center of greatest

hot water usage to reduce heat loss from 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.

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.

Locating The Water Heater continued-

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: THE MANUFACTURER OF THIS WATER HEATER WILL NOT

ACCEPT RESPONSIBILTY FOR DAMAGE TO THE WATER HEATER

CAUSED BY EXPOSURE TO CORROSIVE VAPORS. 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.

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

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 have a minimum length and width of at least 4 in. (10.2 cm) greater

than the diameter 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.

This water heater MUST be installed indoors out of the wind and

weather.

Note: For California installation this water heater must be braced,

anchored, or strapped to avoid falling or moving during an earthquake.

See instructions for correct installation procedures. Instructions may

be obtained from the DSA Headquarters Office, 1102 Q Street, Suite

5100, Sacramento, CA 95811.

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 about 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.

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.

Water Connections continued-

This water heater can deliver scalding temperature water at any faucet in the

system. Be careful whenever using hot water to avoid scalding injury.

Certain appliances, such as dishwashers and automatic clothes washers,

may require increased temperature water. By setting the thermostat on this

water heater to obtain increased temperature water required by these

appliances, you might create the potential for scald injury. To protect against

injury, you should install an ASSE approved mixing valve in the water

system. This valve will reduce point of discharge temperature by mixing cold

and hot water in branch supply lines. Such valves are available from the

manufacturer of this water heater or a local plumbing supplier. Please

consult with a plumbing professional.

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.
