IGNITION AND ADJUSTMENT
Instructions for manual burner operation
Combustion may be checked throughout the entire burner operating
range by controlling the equipment manually.
Set the switch (6) to manual position (MAN).
Use the switch (7) to increase or decrease gas and air.
After completing the check, set the switch (6) to automatic position
(AUT).
• Check that there is water in the boiler and that the system’s
gate valves are open.
• Make absolutely sure that the products of combustion can be
released freely (boiler and flue dampers must be open).
• Check that the voltage of the electrical line corresponds to that
required by the burner. Electrical connections (motor and main line)
must be prepared for the voltage available. Check that all electrical
connections made on-site are performed correctly as shown in
our wiring diagram. To prevent operation of the second flame,
open the second stage thermostat circuit.
• Adjusting power upon first start-up
- Position the ignition gas flow adjustment cam on the electric
servomotor to an opening angle of 35° (0002937530). If it
exists, open the safety valve flow regulator completely.
- Now switch on the switch (1). The command equipment
thus receives voltage and the programmer causes the
burner to switch on as described in chapter “OPERATION
DESCRIPTION”. During preventilation, make sure that the air
pressure control switch changes its status (from the closed
position without pressure measurement to the closed position

with pressure measurement). If the air pressure switch does
not detect sufficient pressure, the ignition transformer (4) is not
switched on, nor are the gas valves (5) and so the equipment
is stopped in “lock-out” (8) mode.
- On first switching on repeated “lock outs” may occur due to
the following reasons:
- The gas piping has not been vented correctly and so there is
not enough gas to provide a stable flame.
- “Lock out” with flame presence could be caused by flame
instability in the ionisation area, due to an incorrect air/gas
ratio.

- in a clockwise direction the air flow increases,
- i n a n a n t i - c l o c k w i s e d i r e c t i o n t h e a i r
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.

After completing first ignition adjustment, turn the switch (7)
