CIB UNIGAS - M039208CA Matching the burner to the boiler The burners described in this manual have been tested with combustion chambers that comply with EN676 regulation and whose dimensions are described in the diagram . In case the burner must be coupled with boilers with a combustion chamber smaller in dia- meter or shorter than those described in the diagram, please contact the supplier, to verify that a correct matching is possible, with res- pect of the application involved. -
Page 11: Hydraulic System
CIB UNIGAS - M039208CA Hydraulic system The pumps that are used can be installed both into single-pipe and double-pipe systems. Single-pipe system: a single pipe drives the oil from the tank to the pump’s inlet. Then, from the pump, the pressurised oil is driven to the nozzle: a part comes out from the nozzle while the othe part goes back to the pump. - Page 12 CIB UNIGAS - M039208CA Suntec TV Pressure governor Pressure adjustment Remove cap-nut 1 and the gasket 2, unscrew the lock nut 4. To increase pressure, twist adjusting screw 3 clockwise. To decrease the pressure, twist screw counterclockwise. Tight the lock nut 4, refit the gasket 2 and the cap nut 1.
- Page 13 Connecting the burner to the light oil pumping unitConnecting the burner to the oil pumping unit Follow the scheme in the picture below to connect the burner to the oil pumping unit. The pump sends the oil coming from the tank to the burner. The pressure governor makes the oil reach the nozzle at the required pressure, while the excess of oil goes back to the tank.

CIB UNIGAS - M039208CA Adjustments - brief description Adjust the air and fuel flow rates at the maximum output (“high flame”) first, by means of the air damper and the adjusting cam respec- tively. Check that the combustion parameters are in the suggested limits. - Page 30 CIB UNIGAS - M039208CA III IV Actuator cams High flame Stand-by and Ignition AUTO Low flame Stroke limitation The nozzle supply pressure is already factory-set and must not be changed. Only if necessary, adjust the supply pressure as fol- lows (see related paragraph);insert a pressure gauge into the port showed on Fig. 17 and act on on the pump adjusting screw VR (see Fig.
