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 HETER.
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 yor building.
·
·

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 orant
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.

If this water heater is installed in a closed water supply system, such as the
one having a back-flow preventer in the cold water supply, provisions shall be
made to control thermal expansion. DO NOT operate
this water heater in a closed system without provisions for controlling thermal
expansion. Your water supplier or local plumbing inspector should be
contacted on how to control this situation
After installation of the water lines, open the main water supply valve and fill
the water heater. While the water heater is filling, open several hot water
faucets to allow air to escape from the water system. When a steady stream
of water flows through the faucets, close them and check all water connections
for possible leaks. NEVER OPERATE THE WATER HEATER WITHOUT
FIRST BEING CERTAIN IT IS FILLED WITH WATER.
WARNING
Hydrogen gas can be produced in an operating water heater that
has not had water drawn from the tank for a long period of time
(generally two weeks or more). Hydrogen gas is extremely
flammable. To prevent the possibility of injury under these
conditions, we recommend the hot water faucet to be open for
several minutes at the kitchen sink before you use any electrical
appliance which is connected to the hot water system. If hydrogen
is present, there will be an unusual sound such as air escaping
through the pipes as hot water begins to flow. Do not smoke or
have open flame near the faucet at the time it is open.
This water heater can deliver scalding temperature water at any faucet in the
system. Be careful whenever using hot water to avoid scalding injury. Certain
appliances such as dishwashers and automatic clothing washers may require
increased temperature water. By setting the thermostat on this water heater
to obtain the increased temperature water required by these appliances, you
may create the potential for scald injury. To protect against injury, you should
install an ASSE approved mixing valve in the water system. This valve will
reduce point of discharge temperature by mixing cold

GAS CONNECTIONS
The gas supply lines must meet all requirements of the National Fuel Gas
Code, ANSI Z223.1 - (Latest Edition) and/or in Canada, CAN/CGA B149
Installation Codes - (Latest Editions).
The minimum permissible gas supply pressure for the purpose of input
adjustment is one (1.0) inch (.25kPa) water column above the operating
manifold pressure. See the rating plate and combination gas control for the
manifold pressure and gas type. The maximum permissible gas supply
pressure is fourteen (14.0) inches (3.5kPa) water column for natural gas and
liquefied petroleum gases/propane gas.
1. Connect this water heater only to the type of gas (natural or propane
gas) as shown on the rating plate. Use clean 1/2 inch black iron
pipe. (Dirt and scale from the pipe can enter the combination control and
cause it to malfunction). The inlet gas line must hae a drip leg (sediment
trap) installed as close as possible to the water heater’s combination gas
control having a minimum length of three (3) inches (7.6 cm). A ground
joint union must be installed in the gas supply line feeding the water heater
to permit servicing of the water heater. Compounds used on the threaded
joints of the gas piping must be resistant to the action of liquefied
petroleum gases/propane gas.
2. This water heater and its gas connection must be leak tested before
placing the water heater in operation. Check for gas leaks with a
soap and water solution and a brush or a commercial leak detector
fluid. NEVER USE A MATCH OR OPEN FLAME FOR TESTING!
CAUTION
The water heater and its individual shutoff valve must be disconnected from
the gas supply piping system during any pressure testing of the system at
test pressures in excess of 1/2 psi (3.5 kPa). The water heater must be
isolated from the gas supply piping system by closing its manual shutoff
valve during any pressure testing of the gas supply system at test
pressures equal to or less than 1/2 psi (3.5 kPa). The supply line must be
capped when not connected to the water heater.

THERMOSTAT ADJUSTMENT
The thermostat dial is set to its lowest temperature setting when shipped from
the factory. Remember that lower temperature settings are more energy
efficient. Adjust the temperature by turning the thermostat dial. It is
suggested that the starting point setting not be greater than the “ ” mark on
the thermostat dial (approximately 120°F [49°C]) as indicated below. Rotate
the thermostat dial clockwise
Rotate the thermostat dial counterclockwise
to increase the temperature setting.
to decrease the
temperature setting. Adjust the dial until the minimum acceptable temperature
is achieved (See figure below for approximate temperature settings).
Figure 16
DANGER
Hotter water increases the risk of scald injury. Scalding may occur within
five (5) seconds at a temperature setting of 135°F (57° C). To protect
against hot water injury, install an ASSE approved mixing valve in the
water system. This valve will reduce point of discharge temperature by
mixing cold and hot water in branch water lines. A licensed plumbing
professional or local plumbing authority should be consulted.
Note: This water heater is equipped with an energy cut out device to
prevent overheating. Should overheating occur or the gas supply fail to
shut off, turn off the manual gas control valve to the appliance and call a
qualified service technician.
Note: Whenever the water heater is filled with cold water, condensate will
form on the cool tank surface and drops of water will fall on the hot burner
and combustion chamber surfaces producing a “sizzling” noise.
Condensation is normal and does not indicate a leak. It will disappear
when the tank becomes heated.

seats properly without leaking and operates freely.
WARNING
When lifting lever of the combination temperatue and pressure
relief valve, hot water will be released under pressure. Be careful
that any released water does not result in bodily injury or property
damage.
8. Monthly, drain off a gallon of water to remove silt and sediment by using
the water heater’s drain valve.
WARNING! THIS WATER MAY BE HOT.
9. If the combination temperature and pressure relief valve on the appliance
discharges periodically, this may be due to thermal expansion in a closed
water supply system. Contact the water supplier or local plumbing
inspector on how to correct this situation. Do not plug the combination
temperature and pressure relief valve outlet.
10. A comination sacrificial anode rod/hot water outlet nipple has been
installed to extend tank life. The anode rod should be inspected
periodically (every two years) and replaced when necessary to prolong
tank life. Contact the plumbing professional who installed the water heater
or the manufacturer listed on the rating plate for anode replacement
information. The use of a water softener may increase the speed of anode
consumption. More frequent inspection of the anode is needed when
