    C.I.B. UNIGAS - M039116CE PART I: INSTALLATION GENERAL FEATURES Burners of this series are characterised by high performaces and width of the performance curves, when the pressure in the combu- stion chamber is high. They are also characterised by other important functional features: there are plugs which can be easily con- nected to the boiler and to the detecting probes, a pressure plug in the combustion chamber, all mechanical components are mounted on a plate which can be quickly taken off for maintenance.

    C.I.B. UNIGAS - M039116CE How to interpret the burner’s “Performance curve” To check if the burner is suitable for the boiler to which it must be installled, the following parameters are needed: furnace input, in kW or kcal/h (kW = kcal/h / 860); backpressure (data are available on the boiler’s ID plate or in the user’s manual).

    C.I.B. UNIGAS - M039116CE Assembling the flexible light oil hoses To connect the flexible light oil hoses to the pump P, proceed as follows : remove the burner cover; Remove the light oil pump inlet and return line plugs. Screw the rotating nut of the two flexible hoses on the pump being careful to avoid inverting the inlet and return lines.

  • Page 13: About The Use Of Fuel Pumps

    C.I.B. UNIGAS - M039116CE About the use of fuel pumps Make sure that the by-pass plug is not used in a single pipe installation, because the fuel unit will not function properly and damage to the pump and burner motor could result. Do not use fuel with additives to avoid the possible formation over time of compounds which may deposit between the gear teeth, thus obstructing them.

    C.I.B. UNIGAS - M039116CE Fig. 14 Fig. 13 Disassembling the nozzle Before disassembling the nozzle, measure the real position “A” (see Tab. 5) and make a note in the panel below. Unscrew the V screw that fastens the combustion head and remove the head from the nozzle-holder (Fig. 15 - Fig. 16). In order to remove the nozzle, it is important to use two wrenches as shown in ,to avoid damaging the burner compo- nent plate! Reassemble the combustion head by respecting the position A measured previously, making sure to fasten the V screw (Fig.
