- Page 19 PART II: INSTALLATION ELECTRICAL CONNECTIONS WARNING: (only for double stage and progressive burners) The burner is provided with an electrical bridge between terminals 6 and 7; when connecting the high/low flame thermostat, remove this bridge before connecting the thermostat. Any cable connection or hook-up to the grid must be carried out by qualified, informed and trained personnel, directly coordinated and authorized by Technical Service.
- Page 20 PART II: INSTALLATION Note on elecrtical supply If the power supply to the burner is 230V three-phase or 230V phase-phase (without a neutral), with the Siemens control box, between the terminal 2 (terminal X3-04-4 in case of LMV2x, LMV3x, LMV5x, LME7x) on the board and the earth terminal, an RC Siemens RC466890660 filter must be inserted.
- Page 21 PART III: OPERATION PART III: OPERATION DANGER! Incorrect motor rotation can seriously damage property and injure people.WARNING: 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”.

If it is necessary to change the burner output in the low flame stage, move the low flame cam: the low flame position matches the ignition position. As far as burners fitted with Dungs MBC gas valves, the low flame cam does not match the ignition cam position, that is why it must be set at about 30°...
- Page 26 PART III: OPERATION Progressive burners Once the procedure till step 8 described is accomplished, go on as follows: set the low flame cam matching the high flame cam; 10 set the TAB thermostat to the minimum in order that the actuator moves progressively towards the low flame position; The manual air damper control is not provided on these actuators.
- Page 27 PART III: OPERATION Fully-modulating burners .To adjust the fully-modulating burners, use the CMF switch on the burner control panel (see next picture), instead of the TAB thermo- stat as described on the previous paragraphs about the progressive burners. Go on adjusting the burner as described before, paying attention to use the CMF switch intead of TAB.
