AIR DAMPER ADJUSTMENT
The air damper (1) is operated by the motor (2)
and assures that the air damper is fully open be-
fore the burner start cycle begins .
The regulation of the air plate is made by adjusting
the disc (3) after releasing the screws (4).
When optimum setting is reached, tighten the
screws (4), the air damper leaves the factory set
at position 3.
COMBUSTION-HEAD ADJUSTMENT
Loose the screw (A), move the elbow (B) so that
the rear plan of the coupling (C) coincides with the
set point. Tight the screw (A).
Example:
The burner is installed on a 81 kW boiler with an
efficiency of 90%, the burner input is about 90 kW
using the diagram below, the combustion set
point is 3.
