Checking / installing the combustion components
Filter replacement
• The multiblock filter screen (only
applies to MBC...) must be checked at
least once a year and if it is clogged it
must be replaced (see page 22).
• Close the main gas shutting valve, and
protect it to prevent from unintended
opening.
• Vent carefully the gas pipe et check
that no pressure is available.
• Loosen the screws on the multiblock
cover.
• Remove the filter element and clean its
housing.
• Do not use any pressurised cleaning
products.
• Replace the filter element with a new
element.
• Screw the cover back into place.
• Reopen the manual gate valve.
• Check it is airtight.
• Check the combustion values.
Cleaning the cover
• Do not use abrasive products or
products containing chlorine.
• Clean the cover with water and a
suitable cleaning product.
• Refit the cover.
Cleaning the burner body
• Do not use any cleaning product with
hydrocarbon-based solvent.
• Cleaning products based on surface
active agents are allowed.
Installing the combustion components
• Check that the ring seal J1 is fitted and in
the correct position on the gas elbow
flange.
• Check the deflector (if it is dirty or sooty,
clean it).
• Check the nozzles (if they are clogged, dirty
or damaged replace them).
• Check the ignition transformers
• Check the electrode settings
• Check the ignition cables
• Check the quick-action coupling for the fuel-
oil connection
• Connect the ignition cable to the electrodes
and the transformers (warning: do not
confuse the connections for the fuel-oil and
gas)
• Connect to the oil supply.
• Insert the combustion components into the
flame tube, tighten the securing screws S3.
• Connect the ionisation cable and the
ignition cable to the combustion
components
• Connect the ignition cable to the ignition
transformer T1.
Important
If the system is converted from natural gas
type E to L or LL or vice versa, the burner
must be reset.
It is not necessary to modify the combustion
components.

Important
After every operation: check the
combustion parameters and real
operating condition (doors closed,
cover fitted etc.). Record the results
in the relevant documents.
Important
Once the pressure switches have
been set, they must be protected to
prevent settings from being altered.
For example, this can be done by
placing a spot of varnish on at least
one of the screws on the equipment's
protective cover.
After the burner is maintained or after
safety device equipment settings for
the burner have been changed (e.g.
pressure switches), the safety
equipment for the burner must be
checked to ensure it is working
properly. After burner
maintenance, the boiler safety chain
must also be checked to ensure that
it is working properly in accordance
with the current specifications. This
check must be carried out with the
operator's agreement.

Checking the flue gas temperature
• Check the flue gas temperature at
regular intervals.
• Clean the boiler if the flue gas
temperature is more than 30 °C above
the value measured at the time of
commissioning.
• Use a flue gas temperature gauge to
make the check easier.
