MAINTENANCE
To maintain maximum functionality and efficiency, and to comply with the relevant legislation, have the boiler inspected
at regular intervals.
When performing maintenance, always follow the precautions listed in the “GENERAL SAFETY INFORMATION” and
"PRECAUTIONS" sections.
Always switch the boiler off if any work or servicing has to be done on other equipment installed near the flue pipes
and/or flues and associated accessories. On completion of work, have the efficiency of the flues checked by qualified
personnel.
IMPORTANT:
Switch the boiler off at its control panel and at the mains power switch, and turn off the gas supply by
closing the gas shut-off cock before performing any cleaning or maintenance on the boiler.
Scheduled maintenance
Scheduled maintenance normally consists of the fol-
lowing operations.
- Removal of encrustations from the burner
- Removal of encrustations from the heat exchangers
- Checking and general cleaning of the flue pipes
- Checking of the efficiency of the external casing
- Checking of ignition, normal functioning and shutdown
of the boiler in DHW and CH modes
- Checking of the gas and water pipe joint tightness
- Checking of gas consumption at maximum and mini-
mum power
- Checking of the position of the ignition and flame detec-
tion electrode
- Checking of the gas failure safety system.
Do not use
flammable substances (e.g. petrol, alcohol
etc.) to clean the boiler or any of its parts.
Do not use paint thinners to clean the casing or any pain-
ted or plastic parts of the boiler. Use only soapy water to
clean the boiler casing.
Extraordinary maintenance
Extraordinary maintenance involves actions designed to
restore the functioning of the boiler to its design specifi-
cations and legal requirements after a failure or malfun-
ction. These actions can be:
- Part replacements
- Repairs
- Reconditioning of components.
These actions generally require special tools and
equipment.

to be drained, closely follow the CH system fil-
ling and start-up instructions on pages 28 and
