ATTENTION: BEFORE EXECUTING THE CONNECTIONS TO THE GAS PIPE NETWORK, BE SURE THAT THE MANUAL CUTOFF VALVES ARE CLOSED.
  • Page 17 PART II: INSTALLATION ATTENTION: it is recommended to mount filter and gas valves to avoid that extraneous material drops inside the valves, during maintenance and cleaning operation of the filters (both the filters outside the valves group and the ones built-in the gas valves). The procedures of installation fo the gas valves are showed in the next paragraphs, according to the gas train used: threaded gas trains with Siemens VGD20..

  • Page 24 PART III: OPERATION AIR FLOW AND FUEL ADJUSTMENT WARNING! During commissioning operations, do not let the burner operate with insufficient air flow (danger of formation of carbon monoxide); if this should happen, make the fuel decrease slowly until the normal combustion values are achieved.
  • Page 25 PART III: OPERATION Siemens VGD.. To adjust the air flow rate in the high flame stage, loose the RA nut and screw VRA as to get the desired air flow rate: moving the rod TR towards the air damper shaft, the air damper opens and consequently the air flow rate increases, moving it far from the shaft the air damper closes and the air flow rate decreases.
