tective equipment (PPE) required by
applicable law.
Note: the list of possible PPE is not
complete as they are indicated by the

ATTENTION:
before performing any maintenance
operation, make sure:
- you have disconnected the power to
the appliance;
- you have closed the gas cock;
- you have discharged the pressure from
the system and domestic hot water
circuit.
Risk of material damage after using sprays and liq-
uids to search for leaks.

During installation and maintenance, do not use spray
or liquids in the upper area of the gas valve (side referring to the
electric connections)
Supply of spare parts.
The device's warranty shall be rendered null and void
if unapproved or unsuitable parts are used for main-
tenance or repairs. These will also compromise the

longer be valid and fail to meet the current regulations.
With regard to the above, only use Immergas original spare parts
when replacing parts.
If additional documentation needs to be consulted for
extraordinary maintenance, contact the Authorised
