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
Before starting maintenance and/or cleaning:
- Set the main system switch (IG) to “OFF”
- Close the fuel shut-off valves.
EXTERNAL CLEANING
The outer casing should be cleaned with cloths dampened
with water and detergent. In the case of stubborn stains,

alcohol or with special products.
After cleaning, dry the appliance thoroughly.

WARNINGS
•
If replacing parts, use EXCLUSIVELY original spare parts.
•
Never use abrasive products, benzene or trichloroethane.
INTERNAL CLEANING
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 boiler. If necessary,
chemically remove all residue using products compatible
with steel (the material of the heat exchanger).
At the end of cleaning, remove/vacuum all residue.
