T'stat information Continued-
CAUTION: Do not operate the burner if it is wet. If the burner gets wet, have
a qualified technician examine the burner before putting it back into operation.
Installing the Thermostat: The water heater comes with the thermostat well
installed in the tank. A Honeywell Aquastat 4103A1100 needs to be installed
in the thermostat well.
Adjusting the Thermostat: When adjusting the thermostat it should be
remembered that lower temperature settings are more energy efficient. To
adjust the thermostat, turn the dial clockwise to decrease the temperature and
counter-clockwise to increase the temperature. It is suggested that the
starting setting not exceed 120°F on the thermostat dial as indicated in (Figure
4).
Hotter water increases the risk of scald injury. Scalding may occur within
five (5) seconds at a temperature setting of 140°F. To protect against hot
water scald injury, install and anti-scald tempering valve in the water
system. This valve will reduce point of discharge temperature by mixing
cold and hot water in branch water lines. A qualified plumber should be
consulted.
