DANGER: There is a
hot water SCALD potential
if the thermostat is set
too high. Households with
small children, disabled or
elderly persons may require
a 120°F or lower thermostat
setting to prevent contact
with HOT water.
Water Temperature Setting
The temperature of the water in the water
heater is regulated by the adjustable
thermostatic gas valve located on the
front of the heater, near the bottom.
Safety and energy conservation are
factors to be considered when selecting
the water temperature setting of the
water heater’s thermostat. The lower the
temperature setting, the greater the
savings in energy and operating costs.
A temperature setting of 120°F or less
is recommended as a useable water
temperature.
To comply with safety regulations, the
thermostat is factory set to a low
setting. “Low” equals approximately
100°F, “Medium” equals approximately
130°F and “High” equals approximately
160°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 on the water heater. This
label is located on the water heater near
the thermostat access panel.
Mixing valves for reducing point of use
water temperature by mixing hot and
cold water in branch water lines are
available. Contact a licensed plumber or
the local plumbing authority for further
information.
The chart below may be used as a guide
in determining the proper water
temperature for your home.
Safety Precautions
Turn off manual gas shut-off valve if water heater
has been subjected to overheating, fire, flood,
physical damage or if the gas supply fails to
shut off.
Do Not turn on water heater unless it is filled
with water.
Do Not turn on water heater if cold water supply
shut-off valve is closed.
Do Not attempt to turn on water heater until
all operating instructions are understood and
followed. See page 17 or label on water heater
near thermostat.
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 must be shut off, including
their pilot lights, to avoid igniting vapors.
NOTE: Flammable vapors may 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 service technician
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 gas is present, there will probably 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.
