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
LOCATING THE WATER HEATER
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.
DO NOT install the water heater in any location where gasoline or
flammable vapors are likely to be present.
Water Heaters in residential garages shall be installed so that all
burner(s) and burner ignition device(s) are located not less than 18
inches (46 cm) above the floor and shall be located, or protected, to
avoid physical damage. For other installations refer to local codes. In
the absence of local codes, the water heater shall be installed in
compliance with the National Fuel Gas Code, ANSI Z223.1 -(Latest
Edition) and/or in Canada, CAN/CGA B149 Installation Codes(Latest
Editions).
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.

Installation (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 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 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!

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 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.
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. Note: The direct vent-air intake terminal must be installed on a
vertical wall. 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 drained, be installed under the water heater.
The pan must not restrict combustion airflow. The drain pan must be no
greater than 1-½ inches (3.8 cm) deep and have a minimum length and width
of at least four (4) inches (10.2 cm) measured from the jacket 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 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.
