INSTRUCTIONS PRIOR TO INSTALLATION
This natural draught boiler is intended to be connected only to a flue shared between multiple dwellings in existing buildings that
evacuates the residues of combustion to the outside of the room containing the boiler. It draws the combustion air directly from the
room and incorporates a draught diverter. Due to lower efficiency, any other use of this boiler shall be avoided and would result in
higher energy consumption and higher operating costs.
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.
The boiler has to be directly connected to an efficient chimney which unloads at the outdoor the products of combustion. The
connection section between boiler and flue must be at least the same as the connection boiler section. The chimney always has
to be under good conditions and does not have to have openings or cracks that can determine dispersions of draught.
Tighten the boiler water connections with care (maximum tightening torque 30 Nm).
10. ELECTRICAL CONNECTIONS
This machine is only electrically safe if it is correctly connected to an efficient earth system in compliance with current safety
regulations.
Connect the boiler to a 230V single-phase earthed power supply using the supplied three-pin cable, observing correct LIVE-
NEUTRAL polarity.
Use a double-pole switch with a contact separation of at least 3 mm.
When replacing the power supply cable, fit a harmonised "HAR H05 W-F" 3x0.75mm
2
cable with a maximum diameter of 8 mm.
Access to the power supply terminal block
• remove the front panel of the boiler (secured at the bottom with two screws);
• turn the control box downwards;
• remove the metal guard from the control box;
• open the left-hand side of the cover and access the electrical connections area.
The 2A fast-blowing fuse is incorporated in the power supply terminal block (to check and/or replace the fuse, pull out the black
fuse carrier).
The terminal block is at high voltage. Before making connections, make sure the appliance is disconnected from the power
supply.
Respect polarity L (LIVE) - N (NEUTRAL).
(L) = Live (brown)
(N) = Neutral (light blue).
