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 large reference mark on the rim of the
temperature dial, represents an
approximate water temperature of 120°F.
The smaller 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.
