MAINTENANCE
E
N
Carry out periodic analysis of the exhaust combustion gas, che-
cking the emissions.
G
Periodically replace the gas filter when dirty.
Check that all the components of the combustion head are in a
L
good state, not deformed by the temperature and free from im-
I
purities or deposits from the installation environment or by poor
combustion and check also the electrodes are working efficiently.
S
If the combustion head needs to be cleaned, remove the compo-
nents following the procedure indicated below:
H
1) Slacken the screws 1 and remove the lid 2 (figure 1).
2) Make sure that mobile plate 3 is held in place by screw 4. This
will permit the mixer unit to be reassembled in the position adju-
sted previously after completion of maintenance work. Slacken
screw 5, which anchors the unit's forward movement rod to the
mobile plate (figure 2).
3) Completely unscrew the nut (6) and tighten the screw (7), mo-
ving it forward inside the gas delivery connection (8) far enough
to permit subsequent dismantling of the mixing unit. Slightly rai-
se the gas delivery union (8) out of its housing (figure 3).
4) Completely remove the mixing unit, pulling it out in the direction
shown by arrow 9, after pulling the ignition and ionisation ca-
bles 10 out of their electrodes (figure 4).
Complete maintenance operations, proceed with re-assembly of
the combustion head, following the above instructions in reverse
order, after having checked the correct position of the ignition and
ionisation electrodes (see diagram 0002935680).
