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.
DANGER
For all boiler installation types, it is necessary to install a filter which can be inspected (Y-shaped type) with Ø 0.4mm-mesh, on the
return pipe before the boiler.
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 ducts to pass through it;
• With reference to the lower part of the template, position the fittings for the connection of:
» gas supply pipe G;
» cold water supply pipe (KC/KR) or return from water heater (KRB) F;
» DHW outlet (KC) or flow to water heater (KRB) C;
» CH flow M;
» CH return R.
• Provide a condensate drain and an outlet for the 3-bar safety valve.
• Hook the boiler to the previously fitted screws.
• Connect the boiler to the feed pipes (see
Hydraulic connections
on page
37
).
• Connect the boiler to an outlet for the 3-bar safety valve.
• Connect the boiler to pipe for condensate drain.
• Connect the boiler to the air intake and flue gas venting system (see
Air intake and flue gas venting system
on page
32
).
• connect power supply, ambient thermostat (when available) and other available accessories (refer to the following paragraphs).
3.5 Boiler room ventilation
The boiler has sealed combustion chamber. Combustion air is not drawn from boiler room, therefore no specific recommendations need to be
applied concerning the boiler room or openings and ventilation provided to the boiler room.
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.
