Jacket cleaning
With a wet cloth, clean all the inner and
outer surfaces of the jacket. Do not use
solvents and / or abrasives products on the
unit.
Flue gas analysis
Combustion control-analysis checks must
be done periodically.
Heat exchanger integrity
Periodically check for cracks and/or
leakages of the heat exchanger
The heat exchanger should be cleaned,
internally and externally, by authorized
personnel and in compliance with specific
rules. In general, we suggest cleaning
the exchanger at least once a year, at the
beginning of every winter.
For such operation, perform the
following operations:
• Disconnect the flue
• Open the inspection door (3)
• Remove inspection door with flue
connection (4)
• Remove the burner (1)
• Remove the panel (2)
• Remove the panel (5)
• Remove the inspection door (6)
• Remove turbulators if present
• With a brush, clean the inside of the
fume pipes (7)
• With a vacuum remove any soot that
has been deposited in the front (8) and
rear (9) manifolds
• If necessary, use a vacuum, remove any
soot that has been deposited inside the
combustion chamber
• If necessary, also remove the side panels
and carry out external cleaning of the
heat exchanger
• Reassemble all the pieces, especially
considering the tightness and replacing
the gaskets, if needed
• If necessary, also clean the flue pipe
Cleaning of the FSE 40 appliance
must be carried out similarly,
considering that the tube
bundle(7) consists of only one
row.
