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. To
adjust the thermostat, turn the dial clockwise until the minimum acceptable
temperature is set. It is suggested that the starting point setting not exceed
the “HOT” mark [approximately 120
°F (49 ° C)] on the thermostat, as indicated
in Figure 2.
Figure 2
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.
