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