GENERAL INFORMATION

This electric water heater’s design is certified by Underwriters Laboratories

(UL) and listed in accordance with UL 1453. C-UL listed in accordance with

Canadian National Standard C22.2, No. 110-M90.

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 latest

edition of the National Electrical Code.

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 certified 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 submerged in water. The

plumbing professional responsible for the installation of this water heater

should be contacted to inspect the appliance and to replace any part of the

control system, including thermostat(s), which has been submerged in water.

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.

CAUTION

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

property and will nullify the warranty.

DANGER

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

corrosive vapors and liquids in the vicinity of this water heater or any

other appliance.

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.

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 probable ignition of gasoline or flammable

vapors.

The location where this water heater is to be installed 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, drain

valves, and clean-out openings are accessible.

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.

WARNING

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

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

shall 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: 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.

This water heater must be located in an area where leakage from the tank,

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.

CLEARANCES

1. Minimum clearance to combustible material is 0 inches for the Top,

Sides, Front, and Rear of this water heater. However, it is

recommended that at least 18 inches (45.7 cm) from the Top, and

24 inches (61 cm) from the Front. Clearance for servicing may be

reduced down to minimum clearance to combustible material, but

service time and effort may be greatly increased.

2. Increase distances to provide clearances for servicing.

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

weather.

To comply with NSF requirements this water heater is to be:

a) Sealed to the floor with sealant, in a smooth and easily cleanable

way, or

b) Installed with an optional leg kit that includes legs and/or extensions

that provide a minimum clearance of 6” beneath the water heater.

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 in order to prevent 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 manual shut-off valve in the cold

water supply line.

This water heater may be provided with an optional pressure and

temperature gauge. See Figure 1 for proper installation.

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 must be

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

closed system without a provision for controlling thermal expansion. Contact

your water supplier or local plumbing inspector regarding how thermal

expansion can be controlled.

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. When a steady stream

of water flows through the faucets, close the faucets and inspect all water

connections for possible leaks. NEVER OPERATE THE WATER HEATER

WITHOUT FIRST BEING CERTAIN IT IS COMPLETELY 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 shall 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 on the water heater, which is provided for this purpose.

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

combination temperature and pressure relief valves. Verify that this

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 provided 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 at a location

where dischargers cannot contact any live electrical part. This discharge

line is to be installed complete drainage of both the temperature and

pressure relief valve and the discharge line can occur. 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 the increased temperature water required by these

appliances, the potential for scald injury is increased. To protect against

injury, install an anti-scald tempering valve in the water system. This valve

will reduce the point of discharge water temperature by mixing cold and hot

water in branch supply lines. Anti-sealed tempering valves can be obtained

from your local plumbing supplier. Please consult a plumbing professional.

WARNING

Hydrogen gas can be produced in the hot water system served by

this water heater when there has been no usage for a long period of

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

flammable. Therefore, 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.
