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 reference mark p on the rim of
the temperature dial, represents an
approximate water temperature of
120°F(49° C).
The reference mark represents an
A
approximate water temperature of
130°F (54° C).
Each reference mark above or below these
points indicates an approximate change of
10°F (5.5°C).
To adjust the temperature, turn the
temperature dial to an initial setting of
120°F (49°C).
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).
100°F (38°C)
90°F (32°C)
80°F (27°C)
45°F (7°C)
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 (shut-off) valve, and DO NOT operate the
water heater again until it has been checked by
a qualified service technician.
NOTICE: DO NOT use this appliance
if any part has been under water.
Immediately call a qualified installer
or service agency to replace a flooded
water heater. DO NOT attempt to
repair the unit! It must be replaced.
