Cleaning the combustion chamber
- Unscrew the 4 closing nuts and open the furnace door
- Brush out the inside of the furnace
- Use a vacuum cleaner to remove any soot which has accumulated
in the combustion chamber
- Close the door and replace the front panel.

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)

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.

To do so:
- Open the left and right cleaning hatches on the flue gas box (2 nuts
H 12 + flat washers with a 19 mm spanner) and remove any soot
which has accumulated using a vacuum cleaner.
- Replace the cleaning hatches.
We advise removing the pipe which connects the boiler to the
chimney and to close off the nozzle with a cover.
