Operating the water heater.

Water Temperature Setting…
Maximum water temperatures occur
just after the burner has shut off.
To determine the water temperature
turn on a hot water faucet and place
a thermometer in the water stream.
The wide reference mark near WARM
on the rim of the temperature dial,
represents an approximate water
temperature of 120°F.
The long wide reference mark, to the
left, represents an approximate
water temperature of 130°F.
Each reference mark above or below
these points indicates an
approximate change of 10°F.
To adjust the temperature, turn the
temperature dial to an initial setting
of 120°F.
A condition known as “stacking” or
“layering” can occur when a series of
short and frequent hot water draws
are taken.
The hottest temperature water will
be at the top of the tank, closest to
the outlet pipe delivering hot water
to
the home.
Stacking can cause this top layer of
water to be hotter than the water
toward the bottom of the tank near
the gas control (thermostat).
Therefore, always remember to test
the water temperature with your
hand before use and remember that
hotter water increases the risk of
scald injury.
Also, always supervise young children
or others who are incapacitated.
The gas control (thermostat) is
constructed with a built in safety
shut-off device designed to shut off
the gas supply to the burner if the
pilot flame is extinguished for any
reason.
The gas control (thermostat) is also
equipped with a single use gas shut
off device that will shut off the gas
supply to the burner if the water
heater exceeds normal operating
temperatures. Refer to the BEFORE
YOU CALL FOR
SERVICE section of this manual, or
contact your dealer.
WARNING: Should overheating
occur or the gas supply fail to shut
off, turn off the manual gas control
valve to the appliance.
If the water heater has been
subjected to fire, flood or physical
damage, turn off the manual gas
control (shut-off) valve, and do not
operate the water heater again until
it has been checked
by qualified personnel.
NOTICE: Replace any part of the
gas control system which has been
under water.
