Periodic maintenance is a compulsory legal requirement and is essential to ensure optimal safety, performance and lifetime
of the appliance.
Internal cleaning of the appliance and removal of combustion residue from the exchange surfaces are operations required
at least once a year. This is an essential condition to reduce consumption, pollutant emissions and to maintain optimal
performance.
MAINTENANCE AND CLEANING

- Set the main switch (IG) of the system and the main
appliance switch (Ip) to “OFF”
- Close the fuel shut-off valves.
EXTERNAL CLEANING

WARNINGS
•
If replacing parts, use EXCLUSIVELY original spare parts.
•
Never use abrasive products, benzene or trichloroethane.
INTERNAL CLEANING OF HEAT EXCHANGER AND
BURNER
To ensure correct operation of the appliance, the burner and
flue lines in the exchanger need to be cleaned periodically.
It is indispensable to mechanically and completely remove
the dirt from the exchanger to avoid the possible formation
of scale during the lifetime of the heating unit. If necessary,
chemically remove all residue using products compatible with
aluminium (the material of the heat exchanger).
After cleaning operations, remove/vacuum all residue from
the condensate collection tank, accessed by opening the
inspection door and also cleaning the condensate collection
syphon. IF IN DOUBT, CONTACT BONGIOANNI CALDAIE
FOR ASSISTANCE.
Panelling disassembly
