Water Temperature Adjustment
The water temperature can be adjusted from 55°F to 155°F.
Turn the Gas Control/Temperature Knob to the desired
setting/temperature.
NOTE: Some models are certified for 180°F outlet
temperatures. See the Data Plate on the front of the water
heater for the maximum outlet 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 55°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.
