Installation 4.11 Gas feeding Explosion danger due to fuel leaks in the pres- ence of a flammable source. Precautions: avoid knocking, attrition, sparks and heat. Make sure that the fuel interception tap is closed before performing any operation on the burner. The fuel supply line must be installed by qualified personnel, in compliance with current standards and laws.
Installation 4.11.2 Gas train Type-approved in accordance with EN 676 and supplied sepa- rately from the burner. 4.11.3 Gas train installation Disconnect the electrical power using the main system switch. DANGER Check that there are no gas leaks. D722 Beware of train movements: danger of crushing of limbs.

For calibration 2), see the table in the wiring diagram. To reset, in case of an intervention of the thermal relay, press the “RESET”...
Start-up, calibration and operation of the burner Start-up, calibration and operation of the burner Notes on safety for the first start-up The first start-up of the burner must be carried out Check the correct working of the adjustment, com- by qualified personnel, as indicated in this manual mand and safety devices.
Start-up, calibration and operation of the burner Burner start-up Feed electricity to the burner via the disconnecting switch on the boiler panel. Close the thermostats/pressure switches and turn the switch 4)(Fig. 6 on page 11) to position “ON”. Make sure that the lamps or testers connected to the solenoids, or indicator lights on the solenoids themselves, show that no voltage is present.
Start-up, calibration and operation of the burner 5.4.2 Maximum gas pressure switch Adjust the maximum gas pressure switch (Fig. 31) after making all other burner adjustments with the maximum gas pressure switch set to the end of the scale. To calibrate the maximum gas pressure switch, open the tap and then connect a pressure gauge to its pressure test point.
