Thermostat Adjustment continued
Figure 8
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 [48.9°C]) as pictured above. Rotate the thermostat dial clockwise to
decrease the temperature setting. Rotate the thermostat dial counter-clockwise
to increase the temperature setting. Adjust the dial until the minimum
acceptable temperature is achieved (See figure 8 above for approximate temperature
settings).
Hotter water increases the risk of scald injury. Scalding may occur within five
(5) seconds at a temperature setting of 140
F (60 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.
