INSTRUCTIONS PRIOR TO INSTALLATION

The following notes and technical instructions are addressed to installers to allow them to carry out trouble-free installation.
Instructions for igniting and using the boiler are contained in the 'Instructions for Users' section. The installation must satisfy the
requirements of local by-laws and technical regulations.
Moreover, the installation technician must be qualified to install heating appliances. Additionally, bear in mind the following:
• This boiler can be connected to any type of double- or single-pipe convector plate, radiator or fancoil unit. Design the system
sections as usual, though, bearing in mind the available capacity-head at the plate (see "SECTION" E at the end of this manual).
• Initial ignition of the boiler must be carried out by the Authorised Service Centre, as indicated on the attached sheet.
ADDITIONAL PUMP WARNING: If an additional pump is used on the heating system, a suitably sized hydraulic separator must
be installed downline from the boiler. This will allow the water pressure switch on the boiler to operate correctly.
SOLAR CIRCUIT WARNING: if the instantaneous (mixed) boiler is connected to a system with solar panels, the maximum
temperature of the domestic hot water entering the boiler must not exceed 60°C.
TEMPERATURE ADJUSTMENT ON LOW TEMPERATURE HEATING SYSTEM: for a low temperature system (such as
underfloor heating), reduce the maximum CH temperature setpoint on the boiler to 45°C) by modifying parameter F06=001 as
described in the SETTING PARAMETERS section.
Failure to observe the above will render the warranty null and void.
Do not leave any packaging (plastic bags, polystyrene, etc.) within the reach of children as they are a potential source of danger.

9. INSTALLING THE BOILER

The template outline is shown in "SECTION C" at the end of this manual.
After deciding the exact location of the boiler, fix the template to the wall. Connect the system to the gas and water inlets present
on the lower bar of the template. Fit two G3/4 taps (flow and return) on the central heating circuit; these taps make it possible to
carry out important operations on the system without draining it completely. If you are either installing the boiler on an existing
system or replacing one, as well as the above, fit a settling tank under the boiler on the system return line in order to collect any
deposits and scale circulating in the system after flushing. After fixing the boiler to the template, connect the flue and air ducts,
supplied as accessories, as described in the following sections.
Tighten the boiler water connections with care (maximum tightening torque 30 Nm).

10. INSTALLING THE DUCTS

The boiler is easy and flexible to install thanks to the extensive range of available
accessories, as described below. The boiler has been designed for connection to a vertical
or horizontal coaxial flue-air duct. The boiler can also be used with separate ducts using
the accessory splitting kit.
For optimal installation, the accessories supplied by the manufacturer should be
used.
To optimise operating safety, make sure the flue ducts are firmly fixed to the wall with
suitable brackets. The brackets must be positioned over the joints at a distance of
approximately 1 metre from one another.

LENGTHS ARE SHOWN IN ANNEX "SECTION" D AT THE END OF THIS MANUAL.
