

do not operate electrical contacts or switches (doorbell,
lights, motor, lift, etc.).

1. Cut the gas supply

2. Open the windows

3. Extinguish all flames

4. Evacuate the premises

5. Contact a qualified professional

6. Inform the gas supplier



Risk of intoxication

Do not obstruct the air inlets in the room (even partially).



In the event of flue gas emanation



1. Switch the appliance off

2. Open the windows

3. Evacuate the premises

4. Contact a qualified professional



Risk of being burnt

Avoid direct contact with the flame viewport.



Depending on the settings of the appliance:



- The temperature of the flue gas conduits may exceed 60°C

- The temperature of the radiators may reach 95°C

- The temperature of the domestic hot water may reach 65°C



Risk of damage

Do not stock chloride or fluoride compounds close to the



appliance.

Install the appliance in frost-free premises.



Do not neglect to service the appliance: Contact a qualified
professional or take out a maintenance contract for the annual
servicing of the appliance.

2.2 Recommendations

Only qualified professionals are authorised to work on the



appliance and the instalation.

Before any work, switch off the mains supply to the



appliance.

Check regularly that the installation contains water and is
pressurised.

Keep the appliance accessible at all times.

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 CO
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

with the values in the table below. Divergent values must be
corrected using the setting screw on the gas multiblock.

d. Then measure the CO

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.

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.

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
the installation or an incorrect setting.

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.
