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 6, for starting, stopping,
and resetting heater procedures.

STORING, TRANSPORTING OR SHIPPING

Note: If shipping, transport companies require fuel tanks to be empty.

1.Drain fuel tank. Note: Some models have drain plug on underside of fuel tank. If so, re- move drain plug to drain all fuel. If heater does not have drain plug, drain fuel through fuel cap opening. Be sure all fuel is removed.

2.Replace drain plug if provided.

3.If any debris is noted in old fuel, add 1 or 2 quarts of clean kerosene to tank, stir, and drain again. This will prevent excess debris from clogging ﬁlters during future use.

4.Replace fuel cap or drain plug. Properly dis- pose of old and dirty fuel. Check with local automotive service stations that recycle oil.

5.If storing, store heater in dry place. Make sure storage place is free of dust and corrosive fumes.

IMPORTANT: Do not store kerosene over summer months for use during next heating season. Using old fuel could damage heater.
