Safety Precautions
DO turn off manual gas shut-off valve if water
heater has been subjected to over heating, fire,
flood, physical 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
newspaper, 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.
Operating the water heater
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 or lower
gas control (thermostat)
setting to prevent contact
with HOT water.
Water Temperature Setting
The temperature of the water in the
water heater can be regulated by setting
the temperature dial on the front of the
gas control (thermostat).
Safety and energy conservation
are factors to be considered when
selecting the water temperature
setting of the water heater’s gas
control (thermostat(s)). The lower the
temperature setting, the greater the
savings in energy and operating costs.
To comply with safety regulations, the
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.
Water temperatures above 125°F 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 gas control thermostat.
Mixing valves are recommended for
reducing point of use water temperature
by mixing hot and cold water in
branch water lines. It is recommended
that a mixing valve complying
with the Standard for Temperature
Actuated Mixing Valves for Hot Water
Distribution Systems, ASSE 1017 be
installed. See page 4 for more details
and contact a licensed plumber or the
local plumbing authority for further
information.
The chart on the next page may be used
as a guide in determining the proper
water temperature for your home.
This water heater is equipped with an
ignition device which automatically
lights the pilot. DO NOT try to light
the pilot by hand. On initial start-up,
it is recommended that the outer door
be removed (leave inner door in place
for safety) to determine if the pilot and
main burner are operating properly.
Once filled with water, plug in the
electrical supply cord and slide the
“ON/OFF” switch located on the front
of the combination gas control to the
“ON” position. Set the thermostat dial
to the desired setting.
After the pilot and main burner ignite,
replace the outer door. If no pilot and
main burner flames are established, the
combination gas control will go through
three trials for ignition before going into
a “lock-out” mode. A warning light will
alert the user of this “lock-out” mode
condition. If this happens, refer to the
“Gas valve LED codes.”
