OPERATION WITH PORTABLE GENERATOR

WARNING: Before operating heater or any appliance from a portable generator, verify that generatorhasbeenproperlycon- nectedtoearthground.Improper grounding or failure to ground generator can result in electro- cution if a ground fault occurs. Refertoowner’smanualsupplied 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 au- tomatic idle feature, the output voltage should be measured with the generator running at full speed).

If the voltage does not measure in this range the
heater should not be plugged into the generator.
Refer to Operation, page 4, for starting, stopping
and resetting heater procedures.
