Flame inspection window
Clean the glass of the flame inspection window (Fig. 38).

Flame presence check
The burner is fitted with an ionisation system to check that a
flame is present (Fig. 39).
The minimum current for control box operation is 6 µA.
The burner provides a much higher current, so controls are not
normally required. However, if it is necessary to measure the ion-
isation current, disconnect the plug-socket 23)(Fig. 5 on page 11)
on the ionisation probe cable and insert a direct current microam-
meter with a base scale of 100 µA.
Carefully check the polarities!
Servomotor
Release cam 4)(Fig. 31 on page 24) from the servomotor, ro-
tating notch 2)(Fig. 31 on page 24) by 90° and manually check
that it rotates smoothly back and forth.
Connect the cam again 4)(Fig. 31 on page 24).
Burner
Check for excess wear or loose screws in the mechanisms con-
trolling the air damper and the gas butterfly valve.
Also make sure that the screws securing the electrical leads in
the burner connections are fully tightened.
Clean the outside of the burner, taking special care with the artic-
ulated couplings and cam 4)(Fig. 31 on page 24).
Fan
Check to make sure that no dust has accumulated inside the fan
or on its blades, as this condition will cause a reduction in the air
flow rate and provoke polluting combustion.

Boiler
Clean the boiler as indicated in its accompanying instructions in
order to maintain all the original combustion characteristics in-
tact, especially the flue gas temperature and combustion cham-
ber pressure.
Combustion
If the combustion values found at the start of the intervention do
not satisfy current standards or anyway indicate a poor state of
combustion (consult the table below), contact the Technical As-
sistance Service for the necessary adjustments.
NOTE:
It is advisable to set the burner according to the type of gas used
and following the indications of Tab. H.
