THERMOSTAT ADJUSTMENT - Honeywell V2 gas control.
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 "HOT" mark on the thermostat dial (approximately 120°F [48.9°C]) as indicated
above. Rotate the thermostat dial counter-clockwise
setting. Rotate the thermostat dial clockwise
Adjust the dial until the minimum acceptable temperature is achieved (See figure 4 above for
approximate temperature settings).
Hotter water increases the risk of scald injury. Scalding may occur within
5 seconds at a temperature setting of 140°F (60
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.
BURNER FLAME CHECKS
Steel Burner: These models are equipped with self adjusting air mixture and
do not have an adjustable air shutter (See Figure 8). At periodic intervals, a
visual check of the main burner and pilot flames should be made to determine
if they are burning properly. The main burner flame should light smoothly
from the pilot.
