COMBUSTION ADJUSTMENT

In conformity with Efficiency Directive 92/42/EEC the application of the burner on the boiler, adjustment and
testing must be carried out observing the instruction manual of the boiler, including verification of the CO and
CO concentration in the flue gases, their temperatures and the average temperature of the water in the boiler.

FUEL HEATING

In order to assure regular ignition and working also at low temperature the burner has an oil pre-heater fit-
ted 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.
