WARNING - CALIFORNIA PROPOSITION

65:This product contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.

!DANGER

Vapors from flammable liquids will explode and catch fire causing death or severe burns.

Do not use or store flammable products such as gasoline sol- vents or adhesives in the same room or area near the water heater.

Keep flammable products:

1.Far away from heater,

2.In approved containers,

3.Tightly closed and

4.Out of children's reach.

Water heater has a main burner and pilot flame.

The pilot flame:

1.Is on all the time or intermit- tently (IID).

2.Will ignite flammable va- pors.

Vapors:

1.Cannot be seen,

2.Are heavier than air,

3.Go a long way on the floor,

4.Can be carried from other rooms to the pilot flame by air currents.

Water temperature over 125°F can cause instant severe burns or death from scalds.

Children, disabled, and elderly are at highest risk of being scalded.

See instruction manual before set- ting temperature at water heater.

Feel water before bathing or show- ering.

Installation:

Do not install water heater where flammable products will be stored or used unless the main burner and pilot flames are at least 18" above the floor. This will reduce, but not eliminate, the

risk of vapors being ignited by the main burner or pilot flame.

Read and follow water heater warnings and instructions.

GENERAL SAFETY

To meet commercial water use needs, the thermostat on this water heater is adjustable up to 190°F. However, water temperatures over 125°F can cause instant severe burns or death from scalds. This is the preferred temperature setting when supplying general purpose hot water.

Safety and energy conservation are factors to be con- sidered when setting the water temperature on the thermostat. The most energy-efficient operation will result when the temperature setting is the lowest that satisfies the needs consistent with the application.

Maximum water temperatures occur just after burner has shut-off. To determine the water temperature being delivered, turn on the hot water only, place a thermometer in the stream, and read the thermometer.

Temperature limiting valves are available, see manual.

The following chart details the relationship of water temperature and time with regard to scald injury and may be used as a guide in determining the safest water temperature for your applications.
