TEMPERATURE ADJUSTMENT

APPROXIMATE TIME/TEMPERATURE RELATIONSHIPS IN SCALDS

120°F (49°C) More than 5 minutes

125°F (52°C) 1½ to 2 minutes

130°F (54°C) About 30 seconds

135°F (57°C) About 10 seconds

140°F (60°C) Less than 5 seconds

145°F (63°C) Less than 3 seconds

150°F (66°C) About 1½ seconds

155°F (68°C) About 1 second

The temperature selector knob of the thermostat has been adjusted to its lowest setting when shipped from the factory.

The marking on the thermostat temperature scale (shown at left) is the preferred starting point

for setting the temperature control. For energy-efficient operation of your water heater, the

suggested initial temperature setting is approximately 120°F (49°C). Households with small

children or invalids may require a 120°F (49°C) or lower temperature setting to reduce the risk

of scald injury. Some states require a lower temperature setting. Full counterclockwise

rotation of the temperature selector dial is the minimum temperature setting. Full clockwise

rotation of the temperature selector dial is the maximum temperature setting. NOTE: The

lower the temperature setting, the greater the energy efficiency, both to heat the water and to

maintain its temperature during standby periods. Lower water temperatures also extend tank

life. Remember, no water heating system will provide exact temperatures at all times. Allow a

few days of operation at this setting to determine the correct temperature setting consistent

This water heater, when set at a lower temperature setting, is not capable of producing hot water of sufficient

temperature for sanitizing purposes.

CAUTION

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.

The lower the temperature setting, the greater the energy efficiency, both to heat the water and to maintain the

storage temperature during standby periods. Lower water temperatures also extend tank life. Remember, no water

heating system will provide exact temperatures at all times. Allow a few days of operation at this setting to determine

the correct temperature setting consistent with the requirements for the installation.

Condensation does not mean your tank is leaking. Over 40% of reported tank leaks on installation are proven to be

condensation. To avoid unnecessary expense and inconvenience, make sure the tank is leaking before calling a

service person.

NOTICE

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.

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.
