General

The boiler does not require complicated maintenance. We nevertheless recommend inspecting it frequently and performing
maintenance on it at regular intervals.
The boiler must be maintained by a qualified installer in accordance with local and national regulations.
Ensure that the boiler is not supplied with voltage.
Replace faulty or worn parts with original spare parts.
Always replace all gaskets on parts removed during inspection and maintenance operations.
Check that all gaskets are correctly positioned (the position is correct and flat in the corresponding groove, which is watertight

Water (drops, splashes) must never come into contact with electrical parts during inspection and maintenance operations due
