OPERATION
MAIN ON/OFF FLAME ON/OFF SWITCH
The ON/OFF switch supplies power to all unit functions. When this switch is in the ON
position the flame effect operates without heat.
LOW HEAT SWITCH
The LOW HEAT ON/OFF SWITCH supplies power to the heater fan and the heater
element. When the switch is in the ON position the heater operates on LOW.
HIGH HEAT SWITCH
The HIGH HEAT ON/OFF SWITCH supplies power to the heater fan and the heater
element, when the switch is in the ON position the heater operates on HIGH. The LOW
HEAT ON/OFF SWITCH must also be in the ON position for the high heat setting to
operate.
RESETTING THE TEMPERATURE CUTOFF SWITCH
The heater is protected with a safety device to prevent overheating. Should the heater
overheat, an automatic cut out will turn the heater off and it will not come back on
without being reset. It can be reset by switching the ON/OFF SWITCH to OFF and
waiting 5 minutes before switching the unit back on.
CAUTION
If you need to continuously reset the heater, unplug the unit and call your local dealer.
