General Instructions
ADJUSTMENT OF BURNER
The burner is from the factory pre-set to an average
value. A final adjustment on site can be necessary.
To adjust the combustion device, start by increasing
the air volume and the nozzle assembly somewhat.
When the burner starts it is burning with excess air
and smoke number 0. Reduce the nozzle assembly
adjustment until soot occurs, and then increase the
adjustment to make the soot disappear again. Then
the volume of air is reduced until soot occurs and in-
creased again to reach a combustion free of soot.
By this procedure an optimum adjustment is ob-
tained.
A whistling sound maybe heard which can be elimi-
nated or reduced as follows: Increase the nozzle as-
sembly adjustment somewhat. The CO
2
-content
and consequently the air volume will then be redu-
ced.
ADJUSTMENT OF NOZZLE ASSEMBLY
Adjust the nozzle assembly with the adjustment
screw D to the desired position.
AIR ADJUSTMENT
First stage:
Set the operating switch on low capacity (burner
operation position "2"). Loosen the screw (A) and
turn the damper to the position wanted. Tighten the
screw (A) again.
Second stage:
Set the operating switch on high capacity (burner
operation "3"). Screw the knurled ring (B) in (redu-
ce) or out (increase). The position of the damper
can be read on the damper scale (C).
Check the air adjustment by making a flue gas ana-
lysis.
