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.
Water heaters in residential garages must be installed and located, or
protected, to avoid physical damage . For other installations refer to local
codes. In the absence of local codes, the water heater must be installed
in compliance with the National Fuel Gas Code, (ANSI Z223.1- Latest
Edition), or in Canada CAN/CGA B149.1 Natural Gas Installation Code
(Latest Edition) or CAN/CGA B149.2 Propane Installation Code (Latest
Edition).
The location of this water heater is of the utmost importance. Before installing
this water, heater read 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 gas and water
supply lines. DO NOT locate the water heater where water lines could be
subjected to freezing temperatures. Make sure the cold-water pipes are
not located directly above the gas control so that condensate during
humid weather does not drip on the controls.
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, thi s 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 DSA Headquarters Office, 1102 Q Street, Suite 5100,
Sacramento, CA 95811.
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 and 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 B Y
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.

WARNING
Liquefied petroleum gases/propane gas are heavier than air and will
remain at floor level if there is a leak. Basements, crawl spaces, closets
and areas below ground level will serve as pockets for accumulation of
leaking gas. Before lighting, smell all around the appliance area for gas.
Be sure to smell next to the floor.
IF YOU SMELL GAS:
• Do not try to light any appliance.
• Do not touch any electric switch; do not use any telephone in your
building.
• Immediately call your gas supplier from a neighbor’s
telephone. Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire department.
DO NOT OPERATE APPLIANCE UNTIL THE LEAKAGE IS
CORRECTED!
DO NOT ATTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE
NOT CERTAIN OF THE FOLLOWING:
• Liquefied petroleum gases/propane gas and natural gas have an
odorant added by the gas supplier that aids in the detection of the
gas.
• Most people recognize this odor as a “sulfur” or “rotten egg” smell.
• Other conditions, such as “odorant fade” can cause the odorant to
diminish in intensity, or “fade”, and not be as readily detectable.
• If you have a diminished sense of smell or are in any way unsure of
the presence of gas, immediately contact your gas supplier from a
neighbor’s telephone.
• Gas detectors are available. Contact your gas supplier, or plumbing
professional, for more information.

After shutting off the main water supply, 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
the top of the water heater. The fittings at the cold -water inlet and hot water
outlet are dielectric waterway fittings with 3/4” NPT male thread. Make the
proper plumbing connections between the water heater and the plumb in g
system to the house. Install a shut-off valve in the cold-water supply lin e .
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.

WARNING
For protection against exces siv e temperat ures 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 produc tion of listed equip me nt or materials as
meeting the requirements of the Standard 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 Va lves . 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 hourly
BTU discharge capacity or the rated steam relief capacity of the
combination temperature and pressure relief valve must not be less than
the 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 that terminates six (6) inches (15 cm) above the
floor, or any distance below the structural floor, to the outlet of the
combination temperature and pressure relief valve. DO NOT allow water
from the discharge line to contact any live electrical part. The discharge line
is to be installed to allow for complete drainage of both the combination
temperature and pressure relief valve and the discharge line. The water
from the discharge line must be directed to a suitable drain or area that will
not be damaged by water Refer to “LOCATING THE WATER HEATER.”
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 clearance 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.

EXCESSIVE TEMPERATURES AND PRESSURES.
If this water heater is installed in a closed water supply system, such as the
one having a back-flow preventer in the cold-water su pply , pr ovis io ns must 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. When a steady stream of
water flows through 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.
Hydrogen gas can be produced in an operating water heater that has not
had water drawn from the tank for a long period of time (generally two (2)
weeks or more). Hydrogen gas is extremely flammable. To prevent the
possibility of injury under these conditions, we recommend the hot water
faucet to be open for several minutes at the kitchen sink before you use any
electrical appliance that is connected to the hot water system. If hydrogen is
present, there will be an unusual sound such as air escaping through the
pipes as hot water begins to flow. Do not smoke or have open flame near
the faucet at the time it is open.
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 clothing washers may require
increased temperature water. By setting the thermostat on this water heater to
obtain the increased temperature water required by these appliances, you
may 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 w ater in br anch
supply lines. Such valves are available from the manufacturer of this water
heater or a local
professional.

WARNING
CAUTION
WARNING
The gas supply lines must meet all requirements of the National Fuel Gas Code (ANSI Z223.1Latest Edition), or in Canada CAN/CGA B149.1 Natural Gas Installation Code (Latest Edition) or
CAN/CGA B149.2 Propane Installation Code (Latest Edition).
The minimum permissible gas supply pressure for the purpose of input adjustment is one (1.0)
inch (0.25 kPa) water column above the operating manifold pressure. See the rating plate and gas
valve for the manifold pressure and gas type. The maximum permissible gas supply pressure is
fourteen (14.0) inches (3.5 kPa) water column for natural gas and liquefied petroleum
gases/propane gas.
1. Connect this water heater only to the type of gas (Natural or Propane gas) as shown on the
rating plate. Use clean black iron pipe or equivalent material approved by local codes and
ordinances. (Dirt and scale from the pipe can enter the gas valve and cause it to
malfunction). The inlet gas line must have a minimum length of three (3) inches (7.6 cm) drip
leg (sediment trap) installed as close to the water heater’s gas valve as possible. A ground
joint union must be installed as close to the water heater as possible in the gas supply line
feeding the water heater to permit servicing of the water heater. Compounds used on the
threaded joints of the gas piping must be resistant to the action of liquefied petroleum
gases/propane gas. DO NOT apply pipe dope to the gas valve inlet and make certain that no
pipe dope has become lodged in the inlet screen of the gas valve. Extreme care must be
taken to ensure no pipe dope enters the gas valve. Avoid excessive torque when tightening
the gas supply line to the gas valve. Excessive torque may result in cracking of the gas valve
housing and could create a gas leak. When tightening gas supply line to L.P. control, it is
recommended to hold the inlet body of the control securely with an adequate wrench. The
suggested maximum torque is 31.5 ft. lbs. (4.4 kg-m).
The manufacturer of this water heater will not be liable for any damage or injury
caused as a result of a cracked gas inlet as a result of excessive torque.
2. This water heater and its gas connection must be leak tested before placing the water heater
in operation. Check for gas leaks with a soap and water solution and a brush or a
commercial leak detector fluid. NEVER USE A MATCH OR OPEN FLAME FOR TESTING!
The water heater and individual shutoff valve must be disconnected from the gas
supply piping system during any pressure testing of the system at test pressures in
excess of 1/2 psi (3.5 kPa). The water heater must be isolated from the gas supply
piping system by closing its manual shutoff valve during any pressure testing of the
gas supply system at test pressures equal to or less than 1/2 psi (3.5 kPa). The
supply line must be capped when not connected to the water heater.
3. While checking for leaks care must be taken to prevent solution from contacting the electrical
connections at the control. If electrical connections at the control become wet, they must be
thoroughly dried before attempting to operate the water heater.
The gas inlet pressure to the gas control must never exceed 14 inches of water
column (1/2 psi). The gas supply system and any pressure regulating device in
the gas line must be specified, inspected and adjusted to assure a gas supply
pressure of 1/2 psi or less. Failure to do so may result in severe injur y or death.

water heater is filled with cold water, condensate will form on the cool tank
surface and drops of water will fall on the hot burner and combustion
chamber surfaces producing a “sizzling” noise. Condensation is normal and
does not indicate a leak. It will disappear when the tank becomes heated.
Burner Flame Checks
At the time of installation and at periodic intervals (not more than six (6) months), a
visual check of the pilot and main burner flames should be conducted. The flames
should be similar to those pictured below. The main burner should light smoothly
from the pilot. (See Figure 13).

IMPORTANT
The water heater should be inspected at a minimum annually by a qualified
service technician for damaged components and/or joints not sealed. DO
The following maintenance should be performed by a qualified service technician at the
minimum periodi c intervals suggested below. In some installations, the maintenance
interval may be more frequent depending on upon the amount of use and the operating
conditions of the water heater. Regular inspection and maintenance of the water heater
and vent-air intake system will help to insure safe and reliable operation.
1. Annually check the operation of the thermostat .
2. The flow of combustion and ventilation air MUST NOT be restricted. Annually
inspect the direct vent-air intake terminal to insure it is not blocked or damaged.
Clear the direct vent-air intake terminal openings of any dirt, dust, or other
restrictions. WARNING! Certain areas of the direct vent-air intake terminal are
HOT.
3. Annually inspect the vent-air intake system to ensure that all components are
securely fastened, and all joints and seams are properly sealed.
4. At all times keep the water heater area clear and free from combustible mat er ia ls,
gasoline and other flammable vapors and liquids.
5. Bi-annually conduct a visual check of the main and pilot burner flames to
determine that they are burning properly. See “BURNER FLAME CHECKS.”

WARNING
6. Annually remove the inner door and main burner assembly to clean orifices and
related parts of any dirt or other foreign material. Inspe ct the burner ports for
obstructions or debris and clean with a wire brush as needed. Wire brush and/or
vacuum clean the combustion chamber as needed t o remov e scale depo sit s and
debris. Inspect the inner door gasket for wear and tear and replace if necessary.
NOTE: It is imperative for proper operation of the water heater that the inner door
be properly sealed.
7. At least once a year, check the combination temperature and pressure relief valve
to ensure that the valve has not become encrusted with lime. Lift the lever at the
lever at the top of the valve several times until the valve seats properly without
leaking and operates freely.
When lifting lever of the combination temperature and pressure relief
valve, hot water will be released under pressure. Be careful that any
released water does not result in bodily injury or property damage.
7. Monthly, drain off a gallon of water to remove silt and sediment by using the
water heater’s drain valve.
THIS WATER MAY BE HOT.
9. If the combination temperature and pressure relief valve on the appliance
discharges periodically, this may be due to thermal expansion in a closed water
supply system. Contact the water supplier or local plumbing inspector on how to
correct this situation. Do not plug the combination temperature and pressure relief
valve outlet.
10. A combination sacrificial anode rod/hot water outlet nipple has been installed to
extend tank life. The anode rod should be inspected periodically (every two (2)
years) and replaced when necessary to prolong tank life. Contact the plumbi ng
professional who installed the water heater, or the manufacturer listed on the
rating plate for anode replacement information. The use of a water softener may
increase the speed of anode consumption. More frequent inspection of the anode
is needed when using softened (or phosphate treated) water.
11. The vent system must be inspected at least once a year to ensure against leakage
of exhaust products.
