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), 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).
•
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.
