AIR ADJUSTMENT
First stage: Set the operating switch on low capacity. Loosen the screw (A) and
move the damper arm (C) along the scale (E) to a position where the flame does
not soot nor blow out. Tighten the screw.
Second stage: The operating switch remains on low capacity. Screw the knurled
ring (B) by means of an adjustment pin in (reduce) or out (increase). The position
of the damper can be read on the damper scale (E).
Check the air adjustments of the second stage by making a flue gas analysis.
