3

Turn the burner on by means of its main switch : if the burner locks press the RESET button on the control panel - see chapter
“OPERATION”.;

4

Start the burner up by means of the thermostat series and wait until the pre-purge time comes to an end and the burner starts up;

5

drive the burner to high flame stage, by means fo the thermostat

TAB

.

6

Then move progressively the microswitch to higher values until it reaches the high flame position; always check the combustion
values and eventually adjusting the gas by means of the valves group governor.

7

go on adjusting air and gas flow rates: check, continuosly, the flue gas analisys, as to avoid combustion with little air; dose the air
according to the gas flow rate change following the steps quoted below;

8

acting on the pressure stabiliser of the valves group, adjust the

gas flow rate in the high flame stage

as to meet the values

requested by the boiler/utilisation:

- Siemens VGD valves group:

remove cap

T

and act on the

VR

adjusting screw to increase or decrease the pressure and conse-

quently the gas rate; screwind

VR

the rate increases, unscrewing it decreases (see next figure).

- Dungs MBC..SE valves group:

act on its pressure governor to increase or decrease the pressure and consequently the gas

rate.

9

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.

Note:

once the procedure is perfomed, be sure that the blocking nut

RA

is fasten. Do not change the position of the air damper

rods.

10 Only if necessary, change the combusiton head position: to let the burner operate at a lower output, loose the

VB

screw and move

progressively back the combustion head towards the MIN position, by turning clockwise the

VRT

ring nut. Fasten

VB

screw when

the adjustment is accomplished.
