General Information continued-
A sacrificial anode(s) is used to extend tank life. Removal of any anode,
except for inspection and/or replacement, 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.
WARNING
This product contains one or more chemicals known to the State of
California to cause cancer, birth defects, or reproductive harm.
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.

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.
