CONTROL BOARD FUNCTIONS

START-UP SEQUENCE OF EVENTS

Once the control panel is turned on, a timer begins that will start, stop and continue operation of the Multi-fuel

Heater as a preset temperature is achieved.

SHUTDOWN SEQUENCE OF EVENTS

Once the Heater has reached the normal operating temperature and switched to the “OFF” position, the unit will initiate a slow down, reducing the fuel rate until the heater’s “LOW LIMIT SAFETY” sensor tells the control board it is safe to shutdown.

CAUTION: When performing any internal electrical maintenance

•Moving parts inside of the cabinet may cause injury. Do not operate unit with panels removed or open.

•HOT parts. Do not operate the unit with panel open.
