Adjustment data
Air regulation
The air intake adjuster
6
is set at the
factory to 1.
Position 1 = max. blower pressure
Position 5 = min. blower pressure
In cases where a higher blower pressure
proves a disadvantage, e.g. large
negative pressure in the combustion
chamber, the pressure can be reduced
by adjusting the air intake adjuster:
• Loosen adjustment screw
7
• Set air intake adjuster to the new value
• Tighten the screw again.
The adjustment data listed above are the default settings. The factory-set adjustment values are outlined in bold. These adjust-
ment values are normally suitable for commissioning the burner. Always check the adjustment values on a case by case basis.
System-specific corrections may be necessary.
Air is regulated at two points:
- On the pressure side of the ventilator
via an air metering drum
- In the burner head via the baffle plate
and burner pipe nozzle.
The air metering drum has a linear
regulating characteristic and is operated
by turning regulating knob
103B
. The
value set can be checked on the control
dial.
The regulation of air in the burner head
influences not only the airflow but also
the mixing zone and the air pressure in
the burner pipe. Turn screw
15
- clockwise = less air
- anti-clockwise = more air
The position of the baffle plate can be
controlled on dial
Y
.
