Operating the water heater
Safety Precautions
Do turn off manual gas shut-off valve if water heater
has been subjected to over heating, fire, flood, physi-
cal damage or if the gas supply fails to shut off.
Do Not turn on water heater unless it is completely
filled with water.
Do Not turn on water heater if cold water supply
shut-off valve is closed.
Do Not allow combustible materials such as newspa-
per, rags or mops to accumulate near
water heater.
Do Not store or use gasoline or other flammable
vapors and liquids, such as adhesives or paint thinner,
in vicinity of this or any other appliance.
If such flammables must be used, open doors
and windows for ventilation, and all gas burning
appliances in the vicinity should be shut off including
their pilot burners, to avoid vapors lighting.
NOTICE: Flammable vapors can be drawn by air
currents from surrounding areas to the water heater.
If there is any difficulty in understanding or following
the Operating Instructions or the Care and Cleaning
section, it is recommended that a qualified person or
serviceman perform the work.
CAUTION: Hydrogen gas can be produced in a hot water system served by this water heater that has not been
used for a long period of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY
FLAMMABLE!! To dissipate such gas and to reduce risk of injury, it is recommended that the hot water faucet
be opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water
system. If hydrogen is present, there will be an unusual sound such as air escaping through the pipe as the water
begins to flow. Do not smoke or use an open flame near the faucet at the time it is open.

DANGER: Hotter water
increases the Potential
for Hot Water SCALDS
.
Households with small
children, disabled, or elderly
persons may require a 120°F
(49°C) or lower combination
gas control (thermostat)
setting to prevent contact
with unsafe water
temperatures.
Water Temperature Setting
The temperature of the water in the water
heater can be regulated by pressing the
buttons on the front of the combination
gas control (thermostat).
Safety and energy conservation are factors
to be considered when selecting the water
temperature setting of the water heater’s
combination gas control (thermostat). The
lower the temperature setting, the greater
the savings in energy and operating costs.
To comply with safety regulations, the
combination gas control (thermostat) was
set at its lowest setting before the water
heater was shipped from the factory. The
recommended starting point temperature is
120°F (49°C).
Water temperatures above 125°F (52°C)
can cause severe burns or death from
scalding. Be sure to read and follow the
warnings outlined in this manual and on
the label located on the water heater near
the combination gas control (thermostat).
Mixing valves are available for reducing
point of use water temperature by mixing
hot and cold water in branch water lines.
Contact a licensed plumber or the local
plumbing authority for further informa-
tion.
The chart on the next page may be used
as a guide in determining the appropriate
water temperature for your home.
Operating Procedure
This water heater is equipped with a hot
surface ignitor to light the main burner.
There is no pilot light to be lit, but on initial
start-up, it is recommended that the outer
door be removed (leave inner door in place
for safety) to view through the sight glass if
the hot surface ignitor and main burner are
operating properly.
Once filled with water, it is only neces-
sary to plug the power cord in and make
sure the “ON/OFF” switch located on the
blower assembly is in the “ON” position to
put the water heater into operation. Within
seconds the hot surface ignitor should heat
up, then the gas valve should open and the
main burner ignite. After the main burner
ignites, replace the outer door. If no main
burner flame is established, the combina-
tion gas control will go through three trials
for ignition before going into a lock-out.
A warning light will alert the user of this
lock-out condition. If this happens, refer to
“Troubleshooting Guide.”
TO SHUT OFF WATER HEATER – Turn
switch located on the side of the blower
assembly to the “OFF” position. See dia-
gram on page 43 for location of blower
assembly.
