Fuel Heating; Burner Start-Up Cycle - Riello Burners Gulliver RG1RK Typ 362 T1 Montage- Und Bedienungsanleitung

4.7 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.

Clean the combustion head in the fuel exit area, on the diffuser disc.
Leave the burner working without interruptions for 10 min. and set rightly all the components stated in
this manual. Then carry out a combustion check verifying:
