STARTING UP AND REGULATION
INSTRUCTIONS FOR MANUAL BURNER OPERATION.
Combustion may be checked throughout the entire burner opera-
ting range by controlling the equipment manually.
Set the switch -3 to manual position (MAN).
Use the switch -9 to increase or decrease gas and air.
After completing the check, set the switch -3to automatic position
(AUT).
• Check that there is water in the boiler and that the gate valves
of the system are open.
• Check that the discharge of combustion products through the
boiler gate and flue gate take places freely.
• Check that thee voltage on the mains meets the manufacturer
requirements and that all electrical connections made at the ins-
tallation site are performed properly as illustrated in our wiring
diagram.

IGNITION OUTPUT REGULATION
• Position the first flame air flow rate regulation cam to an ope-
ning angle of 20°-25°. If fitted, open the safety valve flow rate
regulator fully.
• Correct the air flow rate using screw(s) -12 by the air shutter
control lever (34);

• Now turn the switch null on. This powers on the control device,
and the programmer turns on the burner as described in the
chapter "Operation description". During pre-ventilation, make
sure that the air pressure control switch changes its status. If
the air pressure switch does not detect sufficient pressure, the
ignition transformer is not switched on, nor are the gas valves,
and so the equipment is stopped in “lock-out” mode -10.
• On first switching on repeated “lock outs” may occur due to the
following reasons:
- The gas piping is not being freed of air correctly and so
there is not enough gas to provide a stable flame.
- The “lock out” with flame present may be caused by instabi-
lity in the ionisation area, due to an incorrect air/gas ratio.
• Correct the air flow rate using the screw(s) (12).
- clockwise rotation: the air flow increases
- 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.
