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
turning the knob 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 120°F 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.
Operating Procedure
This heater is equipped with an
electronically lit pilot to light the main
burner. The pilot is automatically
lit each time there is a demand for
heating the water. 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, it is necessary
to plug the power cord in and make
sure the gas control switch is in the
“ON” position. The blower will start
and within seconds the pilot will light
followed by the main burner. After
the main burner ignites, replace the
outer door. If no main burner flame
is established, the 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.”
