Combustion head settings indicated in the schedule are valid for most cases.
The setting of the fan output according to the installation should normally be done only through the air
damper. Should one subsequently want to retouch also the setting of the combustion head, with the
burner running, operate on the rod (1) with a 6 mm spanner (2) as follows:
TURN TO THE RIGHT: (sign
In order to increase the volume of air entering the combustion chamber and thus diminishing its pres-
sure.
There is a reduction of CO
(Setting advisable for ignitions at low temperatures).
TURN TO THE LEFT: (sign – )
In order to reduce the volume of air entering the combustion chamber and thus increasing its pressure.
The CO
improves and the adhesion of the flame to the diffuser tends to reduce. (This setting is not

advisable for ignitions at low temperatures).
In any case do not bring the combustion head setting more than one point away from that indicated in
the schedule. One set-point corresponds to 3 turns of the rod; a hole (3) at its end facilitates counting
the number of turns..

AIR DAMPER ADJUSTMENT :
The mobile air damper (A) operated by the jack (B) assures the complete opening of the air intake.
The regulation of the air-rate is made by adjusting the fixed air damper (C), after loosing the screws
(D). When the optimal regulation is reached, screw tight the screws (D) to assure a free movement of
the mobile air damper (A).
The air damper leaves the factory set at position 3.
The settings indicated in the schedule refer to the burner with its metal cover fitted and the combustion
chamber with "zero" depression.
These regulations are purely indicative.
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.
