American National Standard Z21.10.1 and CSA 4.1-M, most current editions at
the time of manufacture. This is a category III water heater.
This water heater must be installed in accordance with local codes or, in the
absence of local codes, the National Fuel Gas Code, ANSI Z223.1-Latest
Edition) and/or in Canada CAN/CGA B149 Installation Codes (Latest Editions).
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 any damage
resulting from alteration and/or failure to comply with these instructions.
This water heater is not design certified for installation in a mobile home. Such
an installation may create a hazardous condition and will nullify the warranty.
Do not use this appliance if any external part to the tank has been submerged
in water. You should contact a qualified service technician to inspect the
appliance and to replace any part of the control system including the
combination gas control which has been submerged in water. See the Gas
Connections section of this manual before servicing or replacing a water heater
that has had any external part to the tank submerged in water.
CAUTION
Incorrect operation of this appliance may create a hazard to life and
property and will nullify the warranty.
WARNING
Prior to connecting the gas supply line to a gas fired water heater,
ensure that the gas supply line does not have moisture/water or
dirt/scale inside the gas line. Commonly this check is done at the lowest
point in the gas distribution system prior to gas burning appliances.
DANGER
Do not store or use gasoline or other flammable, combustible, or
corrosive vapors and liquids in the vicinity of this or any other appliance.
IMPORTANT
Before proceeding, please inspect the water heater and its components for

General Information continued-
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(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.
INSTALLATION
Locating the Water Heater
DO NOT install the water heater in any location where gasoline or
flammable vapors are likely to be present.
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).
CAUTION
This water heater must not be used as a source of construction heat or
during the construction phase of any building.
WARNING
This product contains one or more chemicals known to the State of
California to cause cancer, birth defects, or reproductive harm.
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 MUST 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.

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.
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.
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.
WARNING
Liquefied petroleum gases/propane gases 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!

7
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 installation
instructions. Locate the water heater as close as possible to the vent opening.
Read the venting section in this installation instruction manual 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 piped for proper drainage must be installed under the
water heater. The pan must not restrict combustion air flow. 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.
This water heater MUST be installed indoors out of the wind and weather.
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.
WARNING
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.
