It is prohibited and dangerous to obstruct, even partially, the air intakes for the ventila-
tion of the room where the boiler is installed (UNI 11071 and related standards);
Repairs must only be carried out by authorised service centres using original spare parts.
Therefore, in the case of a problem, deactivate the boiler only (see instructions).
If you smell gas:
• Do not turn on electric switches, the telephone or any other object that could create
sparks.
• Immediately open up the doors and windows to create an air current that cleans the
room.
• Close the gas cocks.
• Request the intervention of professionally qualified personnel.
Before starting the boiler, have a qualified professional check that the gas supply sys-
tem:
• Is perfectly sealed.
• Is the right size for the required flow rate to the boiler.
• Is equipped with the safety and control devices required by current standards;
• Make sure that the installer has connected the safety valve drain to a outlet funnel.
The manufacturer is not responsible for damage caused by the water released when
the safety valve opens, if it is not correctly connected to a drainage system.
• Make sure that the installer has connected the condensate siphon drain to a specific
outlet funnel (UNI 11071 and related standards), which must be implemented in order
to avoid the condensate freezing and ensure it is correctly drained.
Do not touch the unit with wet or damp body parts and/or in bare feet.
If performing structural work or maintenance near the flue gas ducts and/or the flue
gas exhaust devices or their accessories, turn off the unit and, when the work is complete,
have a qualified technician check the efficiency.
