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 setting the
temperature dial 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 heaters
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.
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 below may be used as a guide in
determining the proper water temperature
for your home.
