• the maximum (MAX) so as to get the maximum air and gas delivery.
Ensure that the gas flow adjustment cam in the second
stage of the electric servomotor is positioned at 130°.
- To regulate the gas flow operate the valve pressure regulator.
Consult the instructions related to the installed gas valve
model. Avoid keeping the burner running if the heating
capacity is greater than the maximum amount allowed for
the boiler, to avoid damaging it.
- For adjusting the air flow rate, operate on the screws (12),
correct the rotation angle of the air gate in the suitable position
to guarantee the right quantity for the power burned.
- Check the combustion parameters with appropriate
instruments (C0

• Adjusting first stage power.
After having adjusted the burner in the second stage, put the
burner into the first stage. Turn switch (7) towards the minimum
(MIN) without varying the adjustment of the gas valve already
performed.
- Adjust the gas flow in the 1
st
stage to the desired value using
the adjustment cam IV for servomotor minimum output (see
0002937530).
- If necessary, correct the combustion air supply adjusting the
screw(s) (12).

• Adjusting the flow rate for ignition
- Once adjustment of the first stage has been carried out,
the burner needs to be switched off and check that ignition
occurs properly. If necessary, it is possible to optimise burner
adjustment in the start-up phase proceeding as follows:
- Adjust the gas flow in the start-up phase, using the adjustment
cam III for ignition output adjustment (see 0002937530). It is
often advisable to set cam III at a slightly higher angle than
cam IV for first stage.
- If necessary, correct the combustion air supply adjusting the
screw(s) (12).
• The air pressure switch prevents the opening of the gas valves
if the air pressure is not the foreseen one. The pressure switch
must therefore be adjusted to intervene closing the contact
when the air pressure in the burner reaches a sufficient
value. If the air pressure switch does not detect pressure
greater than that calibrated, the equipment runs through
its cycle but does not switch on the ignition transformer and
does not open the gas valves and so the burner “locks-out”.
To ensure correct operation of the air pressure switch you
must, with burner on and in 1
st
stage, increase its adjustment
until it is triggered and immediately “locks-out” the burner.
Adjust the setting of the pressure switch to a level slightly below
the actual air pressure detected in first stage operation. Release
the burner and check that it starts up correctly.
