    ELECTRICAL CONNECTIONS The three-phase power supply line must have a switch with fuses. Moreover, the Standards require a switch on the burner power supply line, placed outside the boiler room and in an easily accessible position. For the electrical connections (line and thermostats), follow the attached wiring diagram. To carry out the connection of the burner to the power supply line proceed as follows: • Remove the lid by unscrewing the 4 screws (1) in figure 1, without removing the transparent door. In this way the burner’s electrical panel can be accessed. • Loosen the screws (2) and, after removing the cable float plate (3), pass the two 7 and 4-pole plugs through the hole (see figure 2). Fig. 2 • Reposition the cable float plate as in figure 3. Turn the cam (6) so that the plate exerts sufficient pressure on the two cables, then tighten the screws that fasten the plate. Finally connect the two 7 and 4-pole plugs.

  • Page 40: Adjusting The Air On The Combustion Head Starting Up And Regulation With Methane Gas

    \\ADJUSTING THE AIR ON THE COMBUSTION HEAD ADJUSTMENT DIAGRAM HEAD STARTING UP AND REGULATION WITH METHANE GAS The combustion head has an adjustment device so that the air passage between the disk and the combustion head can be opened or closed. It is therefore possible to obtain, by closing the passage, high pressure upstream of the disk even at low capacity. The high speed and turbulence of the air provides for its greater penetration into the fuel and therefore an excellent mixture and flame stability. High air pressure upstream of the disk may be necessary to prevent flame fluctuations, this is particularly essential when the burner works on the furnace that is pressurised and/or at a high thermal load.
