WARNING: Before operating
heater or any appliance from a
portable generator, verify that
generator has been properly con-
nected to earth ground. Improper
grounding or failure to ground
generator can result in electro-
cution if a ground fault occurs.
Refer to owner’s manual supplied
by generator manufacturer for
proper grounding procedures.
Operating voltage range of heater is 108 to
132 Volts (120 Volts +/- 10%). Prior to plug-
ging heater into generator output voltage
should be verified (if generator is equipped
with automatic idle feature, output voltage
should be measured with generator running
at full speed). If voltage does not measure in
this range heater should not be plugged into
generator.
Refer to
Operation,
page 10, for starting, stop-
ping and resetting heater procedures.
