Operating the water heater.
If adjustment is necessary…
Maximum water temperatures occur just
after the burner has shut off. To
determine the hot water temperature
turn on a hot water faucet and place a
thermometer in the hot 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 the desired setting.
The 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 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.
NOTE: Replace any part of the gas control
system which has been under water.
