Setting data for
air regulation
The settings above are
basic settings
.
The factory-set adjustment values are
outlined in bold. These adjustment
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.
Favourable combustion values can be
achieved using the following nozzles:
Danfoss 45° S, 60° S
Steinen 45° S, 60° S
Fluidics 45° S, 60° S
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
3
.
- clockwise = more air
- anti-clockwise = less air
The position of the baffle plate can be
controlled on dial
Y
.
The
baffle plate position
(dimension
C
)
corresponds to the value on the
Y
scale.
It is adjusted to 0 in the factory.
If readjustment is required, proceed as
follows:
• Remove the cover plate by loosening
the catch springs from the inside.
• Move the
Y
scale to the required
position by screwing in or out.
• Refit the cover plate.
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.
