2 Cleaning the casing material

Use a soapy solution and a sponge only. Rinse with clean water and
dry with chamois leather or a soft cloth.

3 Precautions required in the case of long boiler stops (one or more years)

(one or several 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.

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.
Refer to the instructions supplied with the burner.

1 Water level

Regularly check the level of water in the system and top up if
required, taking care that cold water is not added suddenly into the
boiler when it is hot.

2 Draining

We advise you against draining the system unless it is absolutely
necessary.

chimney and to close off the nozzle with a cover.

System maintenance

This operation should be required only a few times in each heating
season, with very low quantities of water; otherwise, look for the leak
and repair it.
