After the gas connections are made, water is in the heater and
the pilot light is ignited, the control must be set to the desired
water temperature.
The recommended water temperature dial setting is at the ar-
row ( ). The water temperature out of the heater at this setting
will be approximately 120
o
F.
If you use hot water frequently and in short spurts, water tem-
perature can occasionally exceed the temperature setting by up
to 30
o
F because of the dynamics of the appliance.
The arrow ( ) setting is the safest and most economical. If
the want hotter water, rotate the water temperature dial coun-
terclockwise (
) to a higher setting. Approximate water
temperature delivered at the different settings is shown in the
following table.
To avoid scald injury, set the control at the lowest setting which
will still deliver your needed hot water.
Set the control to lowest setting by turning water temperature
dial clockwise (
) to the "PILOT LIGHTING" position on
dial (as shown in Figure 3). DONOTFORCE.
Turn gas control knob clockwise to "PILOT".

Be sure to protect babies and the infirm or others with impaired
mobility who cannot get out of the hot water quickly. They are
the people most commonly hurt in scald injuries and in need of
lower temperature and other protection like supervision, point-of
-use temperature control equipment or a system mixing valve.
A point-of-use valve or a system mixing valve can be obtained
from your plumber.
