A sacrificial anode is used to extend tank life. The removal of this anode, for
any reason, will void 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 (Locating the Water Heater) continued-
Note: For California installations, 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, California
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.
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 touch any electrical 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 leakage is corrected!

Installation (Locating the Water Heater) continued-
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 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.
Proper venting practices must be considered when selecting a location for this
water heater. For exact venting specifications, please consult the Venting
section of these Installation and Operating Instructions.
This water heater must be located in an area where leakage of the tank, water
line connections, or 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 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 in. (1.9 cm) in diameter and pitched for proper
drainage.
It is recommended that a minimum clearance of 4 in. (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 shall allow access to the front of the water heater and
adequate clearance shall be provided for servicing and operating this water
heater. The water heater may be installed on either a combustible or noncombustible floor. If the water heater is to be installed directly on carpeting, it
shall be installed on top of a metal or wood panel (or equivalent) extending
beyond the full width and depth of the water heater by at least 3 in. (7.6 cm) in
any direction or, if the appliance is to be installed in an alcove or closet, the
entire floor shall be covered by the panel. If the rating plate or the label on the
front of the heater specifies minimum clearances less than those listed in the
below table, the water heater must be installed in accordance with the
minimum clearances listed on the rating plate or the label on the front of the
heater.
If it is necessary to install this water heater in an alcove, use the clearances
listed in Figure 2.
Figure 2. Minimum Clearances for an Alcove Installation.

Venting
WARNING
The venting system must be installed properly following all local codes or in
the absence of local codes, the National Fuel Gas Code, ANSI Z223.1-Latest
Edition, or in Canada, The Natural Gas and Propane Installation Code, B149Latest Edition. Failure to properly install the venting system could result in
property damage, personal injury, or death.
This water heater has been shipped with a draft hood, also called a draft
diverter, for which it was designed. The water heater must be operated with
this draft hood properly installed on the damper bracket. If ever removed, the
draft hood must be replaced in the same position and properly secured.
WARNING
Carefully inspect the venting system of a replacement water heater installation
before connecting to the venting system. All joints in the vent connector must
be securely fastened with screws and fit tightly together. Inspect the venting
system for signs of deterioration (rust and perforation) and replace any
sections that are not in good condition.
The chimney must be lined and in good condition. Check to make sure the
venting system is properly sized for the water heater. If the venting system
was previously sized for another gas appliance that has been removed, the
venting system may now be too large. Refer to the National Fuel Gas Code
ANSI Z223.1-Latest Edition, or in Canada, the Natural Gas and Propane
Installation Code, B149-Latest Edition, for the correct sizing of venting
systems and common venting with another gas appliance.
Do not vent this water heater into the venting system of another gas appliance
designed to vent under positive pressure.
The water heater should be installed as close as practical to the venting
system to minimize the vent connector length required. Refer to local codes
for the distance limitations on vent connector lengths.
At the completion of the water heater installation, the burner and venting
system must be checked for proper operation with all other commonly vented
appliances in operation. Check for spillage of flue products around the
outside relief opening of the draft hood after several minutes of operation.
The flame from a match should be drawn into the draft hood. Do not use the
water heater or connected equipment if spillage is detected until the problem
is corrected. Refer to the latest edition of the National Fuel Gas Code, or in
Canada, the Natural Gas and Propane Installation Code for complete details
on the “Procedure to Be Followed to Place Equipment in Operation.”
