4.4 Stopping the boiler
1. Deactivate the electricity supply to the boiler. In this way, any
intergrated regulator is switched off.
2. Close the gas valve.
A boiler which is switched off is not protected against
frost.
4.4.1 Precautions to take if there is a danger of frost
Heating circuit:
Use a correctly dosed antifreeze to prevent the heating water
freezing. If this cannot be done, drain the system completely. In all
cases, consult the fitter.
Domestic hot water circuit:
Drain the domestic water tank and pipes.
4.4.2 Precautions to take in the event of prolonged shutdown (one year or more)
- Close the gas valve
- The boiler and the chimney must be swept carefully.
- Close the door of the boiler to prevent the internal circulation of air.
4.5 Commissioning the boiler
4.5.1 Commissioning
Before filling it with water for the first time, rinse the installation and
eliminate solder pearls, metal shavings, grease, and sludge from the
former installation.
Jobs to be done before commissioning for the first time:
1. Ensure that the boiler is switched off
2. Remove the casings on the inspection side
3. Open the main gas valve
4. Check the electrical connections, particularly the earth
5. Fill the boiler and the installation with water (minimum pressure
1.0 bar)
6. Bleed the heating installation
7. Fill the siphon with water
8. Check the connection of the combusted gas evacuation and the
air inlet
9. Empty the gas inlet
10. Open the gas valve on the gas pipe to the boiler
11. Check the admission pressure of the gas PI
12. Check whether the gas connection is leak proof
13. Activate the electricity supply to the boiler
14. Activate the boiler ON switch
15. Operate the circulation pump and check the assembly position
and the rotation direction
16. Set the boiler regulation according to the heating request
17. The boiler starts to operate
You can monitor operation in the menu #TEST INPUTS, parameter
SEQ:
a. Check the setting of the gas/air ratio and, if necessary, correct it.
The check is carried out at high and low speed, while setting
takes place only on the gas multiblock. For checking and setting,
you will need an electronic CO2meter on the basis of O2)) and a
gas manometer.Be sure correctly to close the opening around
the sensor when making the measurement. Connect the gas
manometer between the measuring point PG under the gas
multiblock and the measurement point PL on the venturi.
b. Run the boiler at high speed (forced "high speed" mode) by
pressing keys P% and P$ simultaneously for 2 seconds.
TEST EMISSION appears on the display with .
c. After reaching minimum output, measure the gas value ∆P at the
measurement point PG under the gas block and the
measurement point PL on the venturi and compare the results
with the values in the table below. Divergent values must be
corrected using the setting screw on the gas multiblock.
d. Then measure the CO2percentage and compare it with the value
in the table. If the values exceed the limits shown, correct them
according to the drawing below.
Check the flame via the flame inspection window. It must not go
out.
e. Run the boiler at low speed (forced "low speed" mode) by
pressing keys P% and P$ simultaneously for 2 seconds
then on -. TEST EMISSION appears on the display with .
f. After reaching minimum output, measure the gas value ∆P at the
measurement point PG under the gas block and the
measurement point PL on the venturi and compare the results
with the values in the table below. Divergent values must be
corrected using the setting screw on the gas multiblock.
g. Then measure the CO2percentage and compare it with the value
in the table. If the values exceed the limits shown, correct them
according to the drawing below.
Check the flame via the flame inspection window. It must not go
out.
Repeat the steps as of step e until the measurements match the
values in the table.
If you do not manage to correct the differences, contact our after
sales service.
h. Remove the measuring device and close the measurement
points.
18. Check the gas seal control and the minimum gas pressure
pressure switch (if need be)

Table of CO2- O2values
Set the parameter to a value greater than or equal to 8, depending on
the options connected.
Then set the gas seal control pressure switch to a trigger pressure
equivalent to 50% of the admission pressure. Do not forget that the
admission pressure measured does not affect the closing pressure
(higher).
19. Press the Reset key to return the boiler to "user level"
20. Heat the installation to around 80°C and then stop the boiler
21. Bleed the heating installation and Checking the hydraulic
pressure
22. The boiler is now operational
23. Set the boiler regulation to the desired values
24. Switch the boiler on and fill in the label "Set to"

For other codes not listed here
- Cut the power supply to the boiler.
- Reset the boiler.
- Change the safety control box if the message persists.
• ROOM S.A FAIL., ROOM S.B FAIL., ROOM S.C FAIL.
Automatic operating without room temperature influence.
• OUTL S.B FAIL., OUTL S.C FAIL.
The circuit concerned goes from automatic to manual mode. The
pump turns and the valve is no longer supplied. It may be manually
operated if necessary.
• DHW S. FAILURE
Heating of domestic hot water is no longer ensured. The load
temperature of the dhw tank is the same as the boiler.
• OUTSI. S.FAIL.
The boiler operates on BOILER MAX temperature. The regulation of
the 3-way valve on circuits B or C (if present) is no longer handled.
Nonetheless, the limitation of the maximum temperature is
guaranteed and the valve can be operated manually if necessary.
Reheating the domestic hot water remains ensured.

6.2.2 (Temporary) blockage
The blockage mode is a normal operating mode and therefore
does not indicate a breakdown but a normal boiler operating
status. A blockage code is likely to signal a technical problem in

8 Energy savings
Here are a few tips for saving energy:
- Install reflector panels behind the radiators.
- Do not cover the radiators. Do not hang curtains in front of the
radiators.
- Insulate pipes to prevent thermal losses and condensation.
- Do not obstruct aeration grates (even partially). They help to
reduce humidity in the home. The more humid a home, the more
heating it consumes.
- Turn heating off when airing a room (5 minutes a day is sufficient)
Avoid deregulating the thermostat. Place the start/stop switch on
Off.
- Do not shut down heating completely if you are absent. Lower the
thermostat by 3-4°C.
- Use the sun's heat as much as possible.
- Take showers rather than baths. Use a water-saving shower head.
