OPERATION WITH
PORTABLE
GENERATOR
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.
The operating voltage range of the heater is
108 to 132 Volts (120 Volts +/- 10%). Prior
to plugging heater into generator the output
voltage should be verified (if generator is
equipped with the automatic idle feature, the
output voltage should be measured with the
generator running at full speed). If the volt-
age does not measure in this range the heater
should not be plugged into the generator.
Refer to Operation, pages 4 and 5, for start-
ing, stopping, and resetting heater proce-
dures.
