General Information continued-
IMPORTANT
Before proceeding, please inspect the water heater and its components
for possible damage. DO NOT install any damaged components. If
damage is evident then please contact the supplier where the water
heater was purchased or the manufacturer listed on the rating plate for
replacement parts.
Make sure that you check the rating plate and combination gas control on
the water heater to be certain that the type of gas being supplied
corresponds with the marking on the rating plate and combination gas
control.
A sacrificial anode is used to extend tank life. The 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 the 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.
INSTALLATION
WARNING
Water heaters are heat producing appliances. To avoid damage or injury,
do not store materials against the water heater or vent-air intake system.
Use proper care to avoid unnecessary contact (especially by children)
with the water heater and vent-air intake components. UNDER NO
CIRCUMSTANCES SHALL FLAMMABLE MATERIALS, SUCH AS
GASOLINE OR PAINT THINNER BE USED OR STORED IN THE
VICINITY OF THIS WATER HEATER, VENT-AIR INTAKE SYSTEM OR
IN ANY LOCATION FROM WHICH FUMES COULD REACH THE
WATER HEATER OR VENT-AIR INTAKE SYSTEM.
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 Z223.1Latest Edition), or in Canada CAN/CGA B149.1 Natural Gas Installation
Code (Latest Edition) or CAN/CGA B149.2 Propane Installation Code
(Latest Edition).

Installation (Locating The Water Heater) continued-
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 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 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
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.

Installation (Locating The Water Heater) continued-
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.

Installation (Locating The Water Heater) continued-
The water heater must be located close enough to the outside wall to keep
the venting distance within the maximum distance described in the vent kit’s
installation instructions. Note: The direct vent-air intake terminal must be
installed on a vertical wall. Read the instructions from the vent kit that was
purchased with the water heater before locating 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, adequately drained, must be installed under the water
heater. The pan must not restrict combustion airflow. 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 and must not restrict proper combustion air flow
to 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 at least 3/4 inch (1.9 cm) in diameter
and pitched for proper drainage.
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.
MINIMUM CLEARANCES
WARNING
Failure to adhere to these installation and operating instructions may
create a hazard to life and property and will nullify the warranty.
This installation must allow access to the front of the water heater and
adequate clearance must be provided for servicing and operating this
water heater. The water heater may be installed on either a combustible or
non-combustible floor. If the water heater is to be installed directly on
carpeting, it must be installed on top of a metal or wood panel extending
beyond the full width and depth of the appliance by at least three (3) inches
(76.2 mm) in any direction or, if the appliance is to be installed in an alcove
or closet, the entire floor must be covered by the panel. The minimum
clearances to combustibles for this water heater is: zero (0) inch (0 cm) from
the sides and rear, four (4) inches (10.2 cm) from the front of the jacket, zero
(0) inch (0 cm) from the plenum, zero (0) inch (0 cm) from the air intake
tubes and twelve (12) inches (30.5 cm) from the direct vent-air intake
terminal. (See Figure 1).
