Important
The boiler must be maintained by a qualified installer in
accordance with local and national regulations.
An annual inspection is mandatory.

year.

Important
Adjust the frequency of inspection and service to the conditions of

Used with a high ΔT
Caution
Replace defective or worn parts with original spare parts.
During inspection and maintenance work, always replace all
gaskets on the parts removed.
Check whether all gaskets have been positioned properly
(absolutely flat in the appropriate groove means they are gas,
air and water tight).
During the inspection and maintenance work, water (drops,
splashes) must never come into contact with the electrical parts.
Warning
Always wear safety goggles and a dust mask during cleaning work
(involving compressed air).
