IMPORTANT: Adjusting the thermostat past the 120°F bar on
the temperature dial will increase the risk of scald injury. Hot
water can produce first degree burns within:

NOTE: During low demand periods when hot water is not
being used, a lower thermostat setting will reduce energy
losses and may satisfy your normal hot water needs. If hot
water use is expected to be more than normal, a higher
thermostat setting may be required to meet the increased
demand. When leaving your home for extended periods
(vacations, etc.) turn the temperature dial to its lowest
setting. This will maintain the water at low temperatures with
minimum energy losses and prevent the tank from freezing
during cold weather.

Water Temperature Adjustment
The water temperature setting 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.
NOTE: The temperatures indicated are approximates. The
actual temperature of the heated water may vary.
Operating Modes and Settings
• Standard Mode - The controller adjusts the water heater to
maintain the temperature set by the user.
• The Vacation Setting (VAC) sets the controller at
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 controller temperature setting down to
a temperature that prevents the water in the water heater
from freezing while still conserving energy.
Status Light Code
Normal Flashes:
• 0 Flashes Indicates Control Off/Pilot Out.
• 1 Flash Indicates Normal Operation.
• A continuous light indicates that the gas control
valve/thermostat is shutting down.
Diagnostic Flashes: If the water heater is not working look
for the following diagnostic flashes after lighting the pilot.
For more details see the "Status Light and Diagnostic Code
Troubleshooting Chart."
2 Flashes Indicates Thermopile Voltage Low
4 Flashes Indicates Overheat Failure
5 Flashes Indicates Sensor Failure
7 Flashes Indicates Electronic Control Failure
8 Flashes See "Status Light and Diagnostic Code
Troubleshooting Chart."
