Thermostat Adjustment
The thermostat dial is adjusted to approximately 120°F when shipped from the
factory. When adjusting the thermostat, it should be remembered that lower
temperature settings are more energy efficient. The thermostat cover, to the right
of the gas valve, must be removed when the thermostat is adjusted. To adjust
the thermostat turn the dial clockwise with a screwdriver until the minimum
acceptable temperature is set. It is suggested that the starting point setting not
exceed the 120°F (49°C) or “HOT” setting on the thermostat.

CAUTION
Before adjusting thermostat(s), turn off power supply to the water heater.
Hotter water increases the risk of scald injury. Scalding may occur within five (5)
seconds at a temperature setting of 135°F (57.3°C). To protect against hot
water injury, install an ASSE approved mixing valve in the water system. This
valve will reduce point of discharge water temperatures by mixing cold and hot
water in branch water lines. A licensed plumbing professional or local plumbing
authority should be consulted.
Note: This water heater is equipped with an energy cut out device to prevent
overheating. Should overheating occur, turn off the electrical supply to the water
heater and contact a qualified service technician.
