SETTING OF THE AIR DAMPER SERVOMOTOR 

(see fig. 2)

CAM II

 assures the fully closed position of the air damper, when the burner is

shut down (stand by). It is adjusted by the factory at 0°. 

DO NOT ALTER

.

CAM III

 adjusts the air damper for the ignition and for the minimum output. It is

set at 20° by the factory. Do not decrease that value; it can be increased a little,
following the need of the application.

CAM I

 limits the rotation at the maximum output. It is adjusted at 90° by the fac-

tory. 

DO NOT INCREASE THAT VALUE

: the burner can be damaged.

  

          

5.3

 COMMISSIONING

After completing both the electrical and gas valve connections, set the minimum air and the gas pressure
switches at minimum value; the maximum air pressure switch must be first set at maximum value. These will
be adjusted only at the end of commissioning procedure.
Connect a manometer to the gas pressure test point situated on the burner.

1)

For guidance the following table shows:
– the capacity required by the application;
– the minimum firing rate achieved for each capacity;
– approximate gas pressure measured at the combustion head, depending on the maximum capacity re-

quired;

– the setting for the air damper.          

(

 These values refer to a combustion chamber with 0 [mbar] back pressure at maximum output. 

  2)

For the maximum capacity required, first set the head (section 5.1), and then the manual air damper as
per the table at page 10.
