Never clean or service the boiler without first di-
sconnecting it from the mains electricity supply by
turning the main power switch OFF.
Regular maintenance may be a legal requirement. In
Italy it is required by Presidential Decree 412 of the 26th
August 1993. It is also essential for the safety, efficiency
and durability of the boiler. Proper maintenance keeps
consumption and emissions down, and ensures that
the boiler continues to operate reliably over time.
Perform the following operations before beginning any
maintenance:
− Switch the electricity supply OFF at the system's
main switch and at the control panel.
− Close the fuel shut-off cocks.

On completion of maintenance, the original settings
must be restored and combustion fumes analysed
to verify correct functioning.
