Using an External thermostat
Therefore, in order to activate the External
thermostat, an internal thermostat knob
MUST be set on "Ext. thermo" position.
• When the heater is controlled by the internal / external thermostat or a timer, the heater could turn itself on at any time,
thus extra care must be taken to ensure that the heater is not accidentally turned on without someone nearby who can
immediately attend to any problems when the heater is ignited, operating, and cooling off.

• Before operating the heater from a portable generator, please confi rm that the generator has been properly connected to the
ground earth. To operate the generator without proper grounding may result in electrical shock. Please refer to the owner's
manual supplied by the generator's manufacturer.
The heater operates within the voltage range
of 207Volts to 253Volts for 230V spec./
108Volts to 132Volts for 120V spec. Before
plugging the heater into the generator, the
output voltage of generator should be verifi ed.
