Maintenance
Filter replacement
• The filter element of the must be
checked at least once a year and
replaced if clogged.
• Loosen the screws of the filter cap.
• 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 shut-off 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.
Precautions
After any operation: check the
combustion performance under real
operating conditions (doors shut,
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.
Following maintenance on the
burner, and after its safety system
settings have been modified (e.g. the
pressure switches), the burner's
safety systems must be checked to
ensure they are operating correctly.
Likewise, following burner
maintenance, it is necessary to check
that the boiler's safety chain is
operating correctly in accordance
with the regulations in force. This
check must be carried out with the
user'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.
