Installation / Operation Instruction Manual

Thermostat Adjustment

The thermostat dial is adjusted to its lowest temperature position when shipped

from the factory. When adjusting the thermostat, it should be remembered that

lower temperature settings are more energy efficient. The thermostat cover, on

the right side of the gas valve, shall 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) mark on the thermostat (see Figure 7).

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.
