2 Cleaning the casing material
Use a soapy solution and a sponge only. Rinse with clean water and

3 Precautions required in the case of long boiler stops (one or more years)
The boiler and the chimney must be swept carefully. Close all the
doors of the boiler to prevent air from circulating inside the boiler. We advise removing the pipe which connects the boiler to the
chimney and to close off the nozzle with a cover.
4 Precautions required if the heating is stopped when there is a risk of freezing
We recommend the use of a correctly dosed antifreeze agent to
prevent to the heating circuit from freezing. If this cannot be done,
drain the system completely.
