Safety Precautions
DO turn off manual gas shutoff 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
shutoff 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 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(s). 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 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 slide the switch on the
combination gas control (thermostat) to 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.”
