3.4 Installing the boiler
DANGER
Before connecting the boiler to CH and DHW networks, clean the pipes carefully.
Before commissioning a NEW system, clean it to remove any metal chips due to machining and welding, and any oil and grease that
might negatively affect boiler operation or even damage it in case they get inside it.
Before commissioning a RECONDITIONED system (where radiators have been added, the boiler has been replaced, etc.) thoroughly
clean it to remove any sludge and residues.
Clean the system using standard non acid products, available on the market.
Do not use solvents as they could damage system components.
Furthermore, in the central heating system (either new or reconditioned), it is always advisable to add to water a suitable
percentage of corrosion protectants for multi-metal systems that will create a protective film onto all internal surfaces.
The manufacturer shall not be held responsible in case of damage to people, animals, or property due to failure to follow the
above mentioned instructions.
In order to install the boiler proceed as follows:
• Affix the template to the wall.
• Check that 1 cm to the right and 1 cm to the left of the boiler is left for casing removal;
• Drill two 12 mm diameter holes in the wall for the wall plugs, insert the wall plugs supplied with the boiler and apply and tighten the screws;
• If necessary, provide holes in the wall to allow air intake and/or flue gas venting pipes to pass through it;
• Position the connections for the gas mains pipe G, the cold water inlet pipe F, the hot water outlet pipe C, and the central heating flow M
and return pipes R as indicated at the bottom of the template;
• Hook the boiler to the previously fitted screws;
• Connect the boiler to the feed pipes (see
Hydraulic connections
on page
29
);
• Connect the boiler to the air intake and flue gas venting system (see
Air intake and flue gas venting system
on page
25
);
• connect power supply, ambient thermostat (when available) and other available accessories (refer to the following paragraphs).
3.5 Air intake and flue gas venting system
Flue gas discharge into the atmosphere and air intake/flue gas venting systems must comply with applicable laws and standards in the
country of installation that are considered as fully transcribed herein.
In existing buildings, this natural draught boiler must be connected only to flue pipes shared by several houses to vent the combustion
residues outside the premises inside which boiler is installed.
Boiler takes the air necessary to combustion directly from the installation premises and features a wind-proof flue.
Due to a lower efficiency, any other use of this boiler must be avoided as it would result in a higher energy consumption and higher operating
costs.
DANGER
the boiler must be installed in a room that is compliant with the legislation and standards in force in the country of installation,
which are herein considered as entirely transcribed.
