STARTING UP AND REGULATION
INSTRUCTIONS FOR MANUAL BURNER OPERATION.
Combustion may be checked throughout the entire burner operating
range by controlling the equipment manually.
Set the selector switch (3) to manual position (MAN) ( ).
Act on the selector switch (9) to increase or decrease gas and air
supply.
After completing the check, set the selector switch (3) to automatic
position (AUT) (
).
•
Check that there is water in the boiler and that the gate valves of the
system are open.
•
Make sure that the combustion products may be freely vented
through the boiler and flue dampers.
•
Make sure that the mains voltage corresponds to the manufacturer's
requirements and that all electrical connections made at the
installation site are effected properly as illustrated in our wiring
diagram.

ADJUSTING THE IGNITION POWER
•
Position the first flame air flow rate regulation cam to an opening
angle of 20°-25°. If installed, open the safety valve flow rate
regulator fully.
•
Now switch on the switch (1),(SF) and (S1) and all enabling signals,
this powers on the control device, and the programmer turns on the
burner as described in the chapter "Operation description". During
the pre-ventilation phase make sure that the pressure switch for
controlling air pressure switches over. If the air pressure switch
does not detect sufficient pressure, the ignition transformer is not
switched on, nor are the gas valves, therefore the equipment “locks
out” (10).(4).
•
During the first ignition several “lock outs” may occur due to the
following reasons:
-
The gas piping has not been bled from air correctly and so there
is not enough gas to provide a stable flame.
-
The “lock out” with flame present may be caused by instability in
the ionisation area, due to an incorrect air/gas ratio.
•
Correct the air flow acting on the screw(s) (11), where the bearing
(12) is located:
-
in a clockwise direction the air flow increases
-
in an anticlockwise rotation: the air flow decreases.
•
Proceed with the regulation of the air until a position is found which
allows ignition without resulting in blocking.
•
It may occur that the ionisation current is disturbed by the discharge
current of the ignition transformer (the two currents have a common
path on the burner’s “mass”) so the burner locks out due to an
insufficient ionisation. Invert the supply (230V side) of the ignition
transformer.
•
This problem may also be caused by an insufficient “ground
connection” to the burner’s casing.
