IGNITION AND ADJUSTMENT
• Check that combustion head penetrates the combustion
chamber by the amount requested by the manufacturer of
the boiler. Check that the device that closes the air on the
combustion head is, presumably, in the correct position to supply
the required fuel (the air passage between the disk and the
head must be greatly reduced for low combustion supply and
relatively open when combustion supply is higher). See chapter
“Combustion head adjustment”.
• It is indispensable to carry out a purge of the air contained in
the pipeline, if not done when connecting the burner to the gas
pipeline. All due precautions should be taken and doors and
windows should be opened. Open the pipe union on the pipeline
situated near the burner and then open a little the gas cut-off
cock. When the characteristic odour of gas can be smelled,
close the shut-off valve. Wait long enough for the gas in the
room to disperse, depending on local conditions, then connect
the burner to the gas pipe again.
• Check that there is water in the boiler and that the system gates
are open.
• Make absolutely sure that the products of combustion can be
released freely (boiler and chimney gate must be open).
• Make sure that the voltage of the electric line to which the
• Put the adjustment cam on the air adjustment electric servomotor
(see adjustment instructions 0002933651) in the positions which
are presumed to be appropriate in proportion to the minimum
and maximum modulation and the ignition thermal output.
• Set the desired ratio between gas and air pressure, following the
adjustment instructions of the pneumatic valve in the attached
manual for the gas train installed.
• For initial adjustment operate the burner manually using the
appropriate modulation connector supplied as standard (see
section "Instructions for manual operation of burner"). Now turn
on the I/O (1) switch on the control panel.

Preventilation is carried out with air open and therefore,
at the same time, the regulation servomotor is switched
on and completes the full opening stroke cycle up to
the "maximum" setting. only when the adjustment
servomotor has returned to the "ignition" position
will the control equipment proceed with its program
switching on the transformer and the ignition gas
valves.
during preventilation, make sure that the air pressure
switch changes its status (from the closed position without
pressure measurement to the closed position with pressure
burner is to be connected corresponds to that required by the
burner and that the electrical connections have been prepared
to match the voltage rating available. Check that all electrical
connections made on-site are performed correctly as shown in
our wiring diagram.
• Apply a pressure gauge of appropriate scale to the pressure
intake of gas to indicate the adjustment value (if the amount
of pressure to be used permits, it is preferable to use a water
column instrument; do not use instruments with indicator hands
for low pressures). Rotate the manual head gas pressure

to the modulation maximum thermal output and the furnace
characteristics, following the instructions laid out in the section
"Manual head gas pressure adjustment device".
measurement). If the pressure switch does not detect sufficient
pressure (and does not change status), neither the ignition
transformer nor the pilot flame gas valve are activated and the
equipment locks out. however, an occasional lock-out during the
first stage of ignition is normal, as air is still present in the valve
train pipeline. The air must be vented to obtain a stable flame.
To release, press the “reset” key (8). On first switching on
repeated “lock outs” may occur due to:
- The gas piping not being vented of the air sufficiently so that
the gas flow is insufficient to ensure a stable flame.
- “Lock out” with flame present may be caused by instability in
the ionisation area, due to an incorrect air/gas ratio. This can
be solved by changing the amount of air and/or gas supplied
so as to find the right ratio. This problem could also be caused
by a wrong air/gas distribution in the combustion head. This
can be remedied with the combustion head adjustment
device by closing or opening the air passage further between
combustion head and gas diffuser.
