The chart shown above may be used as a guide in
determining the proper water temperature for your
home.
!
DANGER: 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.
Maximum water temperatures occur just after the
burner has shut off. To find water temperature being
delivered, turn on a hot water faucet and place a
thermometer in the water stream and read the
thermometer. (See page 24 and 25 for more details.)
DANGER
!
HOT
Water temperature over 125°
can cause severe burns
instantly or death from scalds.
Children, disabled and elderly are
at highest risk of being scalded.
See instruction manual before
setting temperature at water
heater.
Feel water before bathing or
showering.
Temperature limiting valves are
available, see manual.

outlined on the label pictured below. This label is also located on the water heater.
IMPORTANT SAFETY INFORMATION.
READ ALL INSTRUCTIONS BEFORE USING.
Time/Temperature Relationship in Scalds

LP and Natural gas have an odorant added to aid in detecting a gas leak. Some people may
not physically be able to smell or recognize this odorant. If you are unsure or unfamiliar with the
smell of LP or natural gas, ask the gas supplier. Other conditions, such as “odorant fade”, which
causes the odorant to diminish in intensity, can also hide or camouflage a gas leak.
DANGER!
LIQUEFIED PETROLEUM (LP - PROPANE OR BUTANE)
AND NATURAL GAS MODELS
● Water heaters utilizing LP gas are different
from natural gas models. A natural gas
water heater will not function safely on LP
gas and vice versa.
● No attempt should ever be made to convert
the water heater from natural gas to LP
gas. To avoid possible equipment damage,
personal injury or fire, do not connect
the water heater to a fuel type not in
accordance with the unit data plate. LP for
LP units. Natural gas for natural gas units.
These units are not certified for any other
fuel type.
● LP appliances should not be installed below
grade (for example, in a basement) if such
installation is prohibited by federal, state
and/or local laws, rules, regulations or
customs.
● LP gas must be used with great caution.
It is heavier than air and will collect first
in lower areas making it hard to detect at
nose level.
● Before attempting to light the water
heater, make sure to look and smell for gas
leaks. Use a soapy solution to check all
gas fittings and connections. Bubbling at
a connection indicates a leak that must be
corrected. When smelling to detect a gas
leak, be sure to sniff near the floor also.
● Gas detectors are recommended in LP
& natural gas applications and their
installation should be in accordance
with the detector manufacturer’s
recommendations and/or local laws, rules,
regulations or customs.
● It is recommended that more than one
method, such as soapy solution, gas
detectors, etc., be used to detect leaks in
gas applications.
!
DANGER: If a gas leak is present or
suspected:
● Do not attempt to find the cause yourself.
● Do not try to light any appliance.
● Do not touch any electrical switch.
● Do not use any phone in your building.
● Leave the house immediately and make sure
your family and pets leave also.
● Leave the doors open for ventilation and
contact the gas supplier, a qualified service
agency or the fire department.
● Stay away from the house (or building)
until the service call has been made, the
leak is corrected and a qualified agency has
determined the area to be safe.
