Airflow Regulation, Fuel-Oil-Pressure Regulation - elco klockner EK03B.24/30 L-Z Betriebsanleitung

Startup
Adjusting the airflow and fuel-oil pressure
The combustion air is regulated at two
points:
· on the pressure side by means of the
opening gap between the turbulator
and the burner tube.
· On the suction side by means of the
air flap actuated by servomotor Y10.

Airflow control in the burner head has
an effect on the air quantity, as well as
on the mixing zone and the air pressure
in the burner tube. Turn adjustment
screw A clockwise to increase airflow,
and anticlockwise to decrease it.
clockwise = increased airflow
–
anticlockwise = reduced airflow
–
· Adjust dimension Y corresponding to
table of settings.
Suction-side airflow regulation is
carried out using an air flap.
This is actuated by servomotor Y10.
The position of the air flap is
determined by adjusting cams I - IV.
Fuel-oil pressure regulation

Checking the negative pressure
The vacuum gauge used for checking
negative pressure (and fitted with an
R1/8" thread) should be attached to
connection 5. Maximum permitted
