Gasoline, as well as other flammable materials and liquids
(adhesives, solvents, etc.), and the vapors they produce, are
extremely dangerous. DO NOT handle, use or store gasoline
or other nammable or combustible materials anywhere near
or in the vicinity of a water heater. The arc drawn in the water
heater controls can ignite these vapors. Failure to do so can
result in property damage, bodily injury, or death.
WATER TEMPERATURE ADJUSTMENT - Safety and energy
conservagon are factors to be considered when selecting the
water temperature setting of water heaters thermostat. Water
tempe_stures above 125°F. can cause severe burns or death
from scalding. Be sure to read and follow the warnings
outlined on the label pictured below. This label is also located
on the water heater near the thermostat access panel

See instruction manual before
setting temperature at water
heater.
Feel water before bathing or
showering.
Temperature limiting valves are
available, sea manual,
NOTE: Households with small children, disabled, or elderly
persons may require a 120_F. or lower thermostat setting to
prevent contact with "HOt _'water.
The temperature of the water in the heater is regulated by the
adjustable surface mounted thermostat(s) located behind the
Jacket Access Panet(s), Dual element heaters have two
thermostats. To comply with safety regulations the
thermostat(s) were set at 120° F. before the water heater was
shipped fron_ the factory.
