- Ensure that the installation has been issued with
a certificate of conformity granted by an approved
organisation (according to the installation stan-
dards),
- Check that the boiler is adequately adapted to the
gas used and that there are no gas leaks.
- Check that the boiler is filled with water and under
pressure (1.5 bar) and there are no leaks,
Never let the pressure drop below 1
bar.
- Check that the electrical connections of the boiler
are correct: 230 V, 50 Hz, earth connection com-
pliant, polarities correct,
- Check that the combustion products outlet is cor-
rectly assembled, that there are no leaks and no
obstruction,
- Check that the heating system ventilations are
not obstructed,
- Check that the condensate siphons of the flues
are filled with water,
- Check that the condensate outlet is connected
properly and there are no leaks.
- Check the system is totally cleaned and had been
cleaned and flushed in accordance with BS 7593.
Failure to do this may invalidate the warranty.
7 - USER INFORMATION
The heating engineer must inform the user about
the unit’s operating mode. In particular the user
must be informed about the function and the opera-
tion of the safety systems and the need for regular
servicing by a qualified person.
8 - COMMISSIONING
- Check that all the water stop valves and the gas
cock are open,
- Activate the boiler’s external electrical circuit-
breaker,
- Press button (14) to ON (Button illuminated).
• The following references will appear one after
the other on the boiler control panel display
(13),
For this example, this means that it is the ver-
sion 3.00 of the LMU management unit and
version 1.01 of the control interface.
When starting up the boiler, the LMU management
unit recognises all the accessories connected (sen-
sors, mixing valve, pumps, etc.) and automatically
checks the values and settings according to the type
of installation.
If a problem occurs, the LED “alarm signal” (11) is
on (red):
• Press RESET (10) to reset the boiler,
• If the alarm persists, consult the list of opera-
ting faults in chapter IV - OPERATING
