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 (49°C)
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 pressing the
buttons 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 (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 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 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 determine if the hot surface ignitor
and main burner are operating properly.
Once filled with water, it is only necessary
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 control (thermostat) should open and
the main burner ignite. 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.”
TO SHUT OFF WATER HEATER – Turn
switch on the blower assembly to the “OFF”
position.
