GENERAL INFORMATION
This gas-fired water heater’s design is certified by CSA International under the
American National Standard Z21.10.1 -(as indicated on the rating plate) and
CSA 4.1-M-(as indicated on the rating plate).
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

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 part 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.
Make sure that you check the rating plate and combination gas control on the

General Information continued-
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
DO NOT install the water heater in any location where gasoline or
flammable vapors are likely to be present.
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.
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.
CAUTION
The National Fuel Gas Code (ANSI Z233.1-or latest edition) and
CAN/CGA (B149.1-or latest edition), expressly prohibits the installation
of a water heater in a garage, unless the unit is installed so that the
burner and ignition devices are at least eighteen (18) inches (46 cm)
above floor level and protected to avoid damage by a moving vehicle.

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 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!

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. 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 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.
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.
