Water Temperature Adjustment

The water temperature can be adjusted from 70°F to 160°F.
Turn the Gas Control/Temperature Knob to the desired
setting/temperature.

Operating Modes and Settings

•

Standard Mode

- The controller adjusts the water

heater to maintain the temperature set by the user.

• Vacation

Setting

- The controller adjusts the water

temperature to approximately 70°F. This setting is
recommended when the water heater is not in use for
a long period of time. This effectively turns the water
heater down to a setting that prevents the water from
freezing.
