  • Page 18 DESCRIPTION OF TWO STAGE PROGRESSIVE OPERATIONS WITH LIGHT OIL COMIST...DSPGM (See BT 8714/2) This is referred to as a 2-stage progressive operation because the passage from the 1st flame to the 2nd flame (from the minimum rate to the maximum pre-established rate) takes place gradually both as delivery of combustion air and of fuel.
  • Page 19 Fuel and combustion air delivery both increase at the same time until they reach maximum value (light oil pressure at the return pressure regulator is equal to about 18 ÷ 20 bar if the pressure at the pump is at the value of 20 ÷ 22 bar).
  • Page 20 After the insertion spark appears, the control box carries voltage to the magnet which, by means of appropriate levers, moves backwards the two rods which intercept the flow (outward and return) of light oil to the nozzle. This moving backwards of the rods also determines a closing of the passage (by-pass) inside the atomizer unit. Consequently, the pump pressure is taken to the normal value of about 20 ÷...

  • Page 27 STARTING UP AND REGULATION WITH LIGHT OIL 1) Check that the characteristics of the nozzle (delivery and spray angle) are suitable for the furnace (see BT 9353/1). If not, replace it. 2) Check that there is fuel in the cistern and that it is, at least visually, suitable for the burner. 3) Check that there is water in the boiler and that the system’s gate valves are open.
  • Page 28 18) The servomotor which regulates the fuel/air delivery starts moving; wait until the disk on which the regulating screws have been fitted, has reached an angle of about 12° (this corresponds to a space taken up by three screws), stop the modulation and return the switch to the “O” position. Carry out a visual control of the flame and proceed, if necessary, with regulating the combustion air by operating as described in point 16.
  • Page 29 REGULATION OF THE COMBUSTION HEAD AND FLAME DISK (See BT 8608/1) The burner is equipped with a combustion head which can be regulated (by moving it backwards or forwards) in such a way as to close more or open more the air passage between the disk and the head. By closing the passage, it is possible to achieve high pressure upstream the disk and therefore high velocity and air turbulence for low inputs as well.
  • Page 30 STARTING UP AND REGULATION WITH METHANE GAS 1) If not already done at the moment of connecting the burner to the gas pipeline, it is indispensable to carry out a purge of the air contained in the pipeline. As a precaution, special care should be taken and doors and windows should be opened.
  • Page 31 UV CELL If the flame detection is carried out with the UV cell, the following should be taken into consideration. Even the slightest greasiness will compromise the passage of the ultraviolet rays through the UV photoelectric cell bulb, thus preventing the sensitive internal element from receiving the quantity of radiation necessary for it to function properly.
  • Page 32 17) The air pressure switch has the job of bringing the control box to a safety shut down if the air pressure is not at the correct value. Therefore, the air pressure switch must be regulated in such a way as to intervene by closing the contact (foreseen to be closed while working) when the air pressure in the burner has reached a sufficient level.
  • Page 33 REGULATION OF THE COMBUSTION HEAD AND FLAME DISK (See BT 8608/1) The burner is equipped with a combustion head which can be regulated (by moving it backwards or forwards) in such a way as to close more or open more the air passage between the disk and the head. By closing the passage, it is possible to achieve high pressure upstream the disk and therefore high velocity and air turbulence for low inputs as well.
  • Page 34 READING GAS (METHANE) METER When the burner is operating at maximum output, check that the quantity of gas delivered is necessary for the boiler’s needs. The low calorific value for methane gas is about 8550 kcal/m To find out the low calorific values of other types of gas, contact the Gas Distributing Company. Delivery per hour should be taken at the meter.
