GENERAL INFORMATION
This electric water heater’s design is certified by INTERTEK (ETL) and listed
in accordance with UL 174. CETL 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
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.
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.
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, 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.
A sacrificial anode is used to extend tank life. Removal of this 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 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.
CAUTION
Incorrect operation of this appliance may create a hazard to life and
property and will nullify the warranty.
Do not store or use gasoline or other flammable, combustible,
or corrosive vapors and liquids in the vicinity of this or any other
appliance.

General Information continued-
INSTALLATION
Locating The Water Heater
This water heater MUST be installed indoors out of the wind and
weather.
This water heater shall 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 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 and drain valves are accessible.
Some models are not equipped with a drain valve. For those models, install
a drain tee in the cold water inlet as close as practical to the water heater.
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.
IMPORTANT
Before proceeding, please inspect the water heater and it’s 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-
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 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.
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.
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 and HOT water outlet are
identified on top of the water heater. The fittings at the cold water inlet and
hot water outlet are dielectric waterway fittings with 3/4” NPT tapered male
threads. Make the proper plumbing connections between the water heater
and the plumbing system in the house. Install a shut-off valve in the cold
water supply line.
