Opening for modules inspection
• Close the voltage and gas feeding
• Unloose the gas inlet connection and
separate the gas feeding pipe from the
boiler
• Remove all the jackets
• Remove the plug “A” for 230V supply
of the boiler
• Remove the cover in order to access
to the electric section
Only for Modulex 360, remove the
electric connection of flow sensor “B”
(black), return “C” (white) and the wa-
ter pressure gauge connection “D”

• Remove the safety spring “H” of the
support bar “L” for upper opening.

The sequence here reported for the
modules inspection is for a MOD-
ULEX 360.
For boilers MODULEX 450, 540
and 630 these steps are a little
different, for example for the cable
removal and for the opening that will
be done on the opposite side (left
side).
• Only for Modulex 450-540-630, remo-
ve the electric connections of the mo-
dules, marked by the label 1…..6 or 7
(limit thermostat, ignition and detection
electrode, hearting and immersion sen-
sor)
5.1 - MAIN FEATURES
If the boiler is correctly adjusted, it about
doesn't need maintenance; it only needs
to be checked once a year and, if nec-
essary, be cleaned. In any case the fre-
quency of the cleaning depends on the
cleaness of the air sucked for the com-
bustion. As much as the dust present in
the air will be sucked inside the com-
bustion chamber, the smoke side resist-
ance will increase, which, finally, will
result in a reduced heat input (and con-
sequently a reduced output).
Before cleaning the boiler body sections,
check the boiler input and the CO
2
per-
centage (see 3.5). If the actual input (with
the correct CO
2
) is within 5% of the value
shown in the chapter 3, the boiler does
not need to be cleaned.
The operation then, can be limited to
the cleaning of the siphon.
Note! A reduction of the input can be
caused by the obstruction of the eva-
cuation duct or of the air intake. Check,
first of all, that this is not the reason.
