DIRECTIVES AND STANDARDS close the gas valves; contact qualified personnel. Gas burners Do not obstruct the ventilation openings of the room where gas  European directives appliances are installed, to avoid dangerous conditions such as the 2016/426/UE (appliances burning gaseous fuels) development of toxic or explosive mixtures.
Page 5 PART I: SPECIFICATIONS PART I: SPECIFICATIONS These burners are designed to be installed into boilers provided with very big combustion chamber but the tube nest very close to the burner stokhole. The flame produced by this burner series is very short, but has the energy necessary to take up all the combustion chamber and then exchange this energy to the water, as to get very high efficiency.

Page 12: Electrical Wiring
PART II: INSTALLATION Electrical wiring Respect the basic safety rules. make sure of the connection to the earthing system. do not reverse the phase and neutral connections. fit a differential thermal magnet switch adequate for connection to the mains. ATTENTION: before executing the electrical connections, pay attention to turn the plant’s switch to OFF and be sure that the burner’s main switch is in 0 position (OFF) too.
Page 13 PART II: INSTALLATION Rotation of fan motor After completing the electrical connection of the burner, remember to check the rotation of the fan motor. The motor should rotate in an anti-clockwise direction looking at cooling fan. In the event of incorrect rotation reverse the three-phase supply and check again the rotation of the motor.
Page 14 PART II: INSTALLATION GAS TRAIN CONNECTIONS The diagrams show the components of the gas train included in the delivery and which must be fitted by the installer.The diagrams are in compliance with the current laws. ATTENTION: BEFORE EXECUTING THE CONNECTIONS TO THE GAS PIPE NETWORK, BE SURE THAT THE MANUAL CUTOFF VALVES ARE CLOSED.
Page 15 PART II: INSTALLATION GAS TRAIN CONNECTIONS WARNING: before executing the connections to the gas pipe network, be sure that the manual cutoff valves are closed. 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).

This check, carried out as soon as the boiler thermostat gives a start signal to the burner, creates, by means of the diaphragm pump inside it, a pressure in the test space of 20 mbar higher than the supply pressure.
Page 20 ADJUSTMENTS ATTENTION: before starting the burner up, be sure that the manual cutoff valves are open and check that the pressure upstream the gas train complies the value quoted on paragraph “Technical specifications”. Be sure that the mains switch is closed.
