Electrodes setting 

Before  removing  or  assembling  the  nozzle,  loosen  the  screw
A)(Fig. 20) and move the electrodes ahead.

8.6

Air damper adjustment

The air damper is set in factory. This regulation is purely indica-
tive.

Each  installation  however,  has  its  own  unpredictable  working
conditions: actual nozzle output; positive or negative pressure in
the combustion-chamber, the need of excess air, etc.

All these conditions may require a different air damper setting.

8.6.1

Main air damper

The main air damper can be set in either of two positions. 

To set the positions of the damper, proceed as follows:

remove  the  secondary  air  damper  B)(Fig. 21)  loosing  the
screws 1). 

Loosen  the  screw  2)  and  rotate  the  main  air  damper  A)  to
the required position. 

Retighten  the  screw  2)  and  put  back  the  secondary  air
damper B).

8.6.2

Secondary air damper

The purpose of this damper is to perform a fine-tuning of the inlet
air.

Tuning of this device is possible acting of the screw 3)(Fig. 22).

WARNING

The position of the electrodes cannot be regulat-
ed.  In  case  of  failure,  check  that  the  measure-
ments as shown on the figure are respected.
