OPERATING INSTRUCTIONS
Water Temperature Regulation
The higher the setting, the greater the risk of
scalding. Hot water can cause third degree burns
in under one (1) second at 150°F (65°C), in six (6)
seconds at 140°F (60°C) and in thirty (30)
seconds at 130°F (54°C). In households where
there are children, physically challenged individuals,
or elderly persons, mixing valves for point of use
are necessary as a means of reducing the
scalding potential of hot water.
The gas control valve is factory-adjusted to its
lowest temperature. The desired water temperature
can be selected by rotating the temperature dial on
the front of the gas control. Turn the temperature dial
clockwise to decrease the temperature, or
counterclockwise to increase the temperature.
The reference mark on the temperature dial, indicated
by a large rectangle, represents 130˚F (54˚C)
(
see figure 10
). Each mark to the left and right of
this reference mark indicates a temperature change
of approximately 10°F (6°C).
When hot water is drawn from the tank in
frequent short bursts, a condition known as “stack-
ing” is created. “Stacking” is the result of increased
cycling of the burner and can produce very hot
water temperatures at the hot water outlet. Always
remember to check the hot water coming out of any
faucet with your hand before use. This will reduce
the risk of scalding-related injury.
The gas control valve is equipped with an energy
cut-off (E.C.O.). Should the temperature of the water
exceed 194˚F (90˚C), the E.C.O. will shut off the gas
supply to the water heater. If the E.C.O. has tripped,
the gas control valve must be replaced immediately
by a qualified service technician.
Should overheating occur or the gas supply fail to
shut off, close the gas supply manual shut-off
valve. Failure to follow this instruction can result in
property damage, personal injury, or death.
Out of Fuel
If your water heater should run out of gas, proceed
as follows:
1) Close the gas supply manual shut-off valve.
2) Depress slightly and turn the gas control knob
clockwise to the “
OFF
” position.
3) Once the gas supply has been re-established,
proceed to the
Lighting Instructions
