Page 5: Part I: Installation
C.I.B. UNIGAS - M039203CC PART I: INSTALLATION GENERAL FEATURES This series represents monobloc gas burners made in die-cast aluminium housing, that can burn either gas or light oil, thanks to the adjustable combustion head which allows a good performance with both fuels. They can be provided in progressive or fully-modulating version. -
Page 6: Checking The Proper Gas Train Size
C.I.B. UNIGAS - M039203CC Checking the proper gas train size To check the proper gas train size, it is necessary to know the available gas pressure value upstream the burner’s gas valve. Then subtract the backpressure. The result is called p Draw a vertical line matching the furnace input value (600kW, in the example), gas. -

Page 18: Gas Filter
C.I.B. UNIGAS - M039203CC ATTENTION: before starting the burner up, be sure that the manual cutoff valves are open and check that the pres- sure upstream the gas train complies the value quoted on paragraph “Technical specifications”. Be sure that the mains switch is closed. - Page 19 C.I.B. UNIGAS - M039203CC Before starting the burner up, drive the high flame actuator microswitch matching the low flame one (in order to let the burner ope- rates at the lowest output) to safely achieve the high flame stage. Start the burner up by means of the thermostat series and wait until the pre-purge time comes to an end and that the burner starts drive the burner to high flame stage, by means fo the thermostat TAB (high/low flame thermostat - see Wiring diagrams), as far as fully-modulating burners, see related paragraph.
