THERMOSTAT ADJUSTMENT

The thermostat dial is set to its lowest temperature setting when shipped from the factory. Remember that lower temperature settings are more energy efficient. Adjust the temperature by turning the thermostat dial. It is suggested that the starting point setting not be greater than the “” mark on the thermostat dial (approximately 120°F [49°C]) as indicated below. Rotate

the thermostat dial clockwise to increase the temperature setting.

Rotate the thermostat dial counterclockwise to decrease the temperature setting. Adjust the dial until the minimum acceptable temperature is achieved (See figure below for approximate temperature settings).

DANGER

Hotter water increases the risk of scald injury. Scalding may occur within five (5) seconds at a temperature setting of 135° F (57° C). To protect against hot water injury, install an ASSE approved mixing valve in the water system. This valve will reduce point of discharge temperature 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 or the gas supply fail to shut off, turn off the manual gas control valve to the appliance and call a qualified service technician.

Note: Whenever the water heater is filled with cold water, condensate will form on the cool tank surface and drops of water will fall on the hot burner and combustion chamber surfaces producing a “sizzling” noise.

Condensation is normal and does not indicate a leak. It will disappear when the tank becomes heated.
