4.4 FUEL HEATING
In order to assure regular ignition and working also at low temperature the burner has an oil pre-heater
fitted in combustion head. The pre-heater starts when thermostats close.
When the required temperature for ignition is reached the thermostat fitted on the nozzle holder starts the
burner. The pre-heater remains energised during working and cuts out when burner shuts-down.
