Installation shutdown
If the central heating system is not used for a long period, we
recommend switching the boiler off.
4 Switch the On/Off switch to Off.
4 Switch off the boiler electrical power supply.
4 Close the oil inlet.
4 Ensure that the boiler and system are protected against frost
damage.
4 The boiler and the chimney must be swept carefully.
4 Close the door of the boiler to prevent the internal circulation of
air.
4 Remove the pipe connecting the boiler to the chimney and plug
the nozzle.
4 Drain the domestic water tank and pipes (For models with
domestic hot water production).
5.5
Antifreeze protection
When the heating water temperature in the boiler is too low, the
integrated boiler protection system starts up. This protection functions
as follows:
4 If the water temperature is lower than 7°C, the heating pump starts
up.
4 If the water temperature is lower than 4°C, the boiler starts up.
4 If the water temperature is higher than 10°C, the boiler shuts down
and the circulation pump continues to run for a short time.
4 If the water temperature in the storage tank is less than 4°C, it is
reheated to its set point.

The antifreeze protection does not function if the
appliance is switched off.
The integrated protection system only protects the
boiler, not the installation. To protect the installation,
set the appliance to HOLIDAYS mode.
The HOLIDAYS mode protects:
4 The installation if the outside temperature is lower than 3°C
(factory setting).
4 The room temperature if a remote control is connected and the
room temperature is lower than 6 °C (factory setting).
4 The domestic hot water tank if the tank temperature is lower

General instructions
The boiler does not require a lot of maintenance. Nevertheless, we
recommend having the boiler inspected and serviced at regular
intervals.
4 Maintenance and cleaning of the boiler must be carried out at least
once a year by a qualified technician.
4 Have the flues swept at least once a year or more, depending on
the regulations in force in your country.
CAUTION
4
Maintenance operations must be done by a qualified
engineer.
We recommend taking out a maintenance contract.
4
Only original spare parts must be used.

Make certain that the flues and chimneys are
connected, in good condition and not blocked.
Do not modify nor block the condensate outlet(s).

water pressure can drop below the required level. Check
the water pressure in the installation shown on the control
panel display. If the water pressure is lower than 0,8 bar,
more water should be added.

15.After filling the installation, switch the boiler on.
6.4
Bleeding the heating system
It is essential that any air in the boiler, pipes or fittings is bled to
prevent noises to occur during heating or water draw-off. To do this,
proceed as follows:
1. Open the valves on all radiators connected to the heating system.

2. Set the heating set point to as high a temperature as possible.
3. Wait until the radiators are hot.

7. Open the bleed connection using the bleed key provided whilst
keeping a rag pressed against the connection.
T000217-A
8. Wait until water comes out of the bleed valve and then close the
bleed connection.
CAUTION
The water may still be hot.
9. Switch on the boiler.
10.Check whether the pressure in the installation is still sufficient.
If the water pressure is lower than 0,8 bar, more water
should be added. If necessary, top up the water level in the
heating system (recommended hydraulic pressure
between 1,5 and 2,0 bar).

Draining the installation
It may become necessary to empty the water from the heating system
when the radiators have to be replaced, should there be a major water
leak or a risk of frost. To do this, proceed as follows:
1. Open the valves on all radiators connected to the heating system.

2. Switch off the boiler electrical power supply.
3. Wait around 10 minutes until the radiators are cold.

4. Connect an evacuation hose to the plug located at the lowest
level. Place the end of the hose in a discharge sump or in a place
where the water discharged from the valve can not do any
damage.
5. Open the filling/draw-off valve on the heating system. Vent the
heating installation.
WARNING
The water may still be hot.

6. When no more water comes out of the drainage plug, close the
drainage valve.

Anti-hunting
When the boiler is in Anti-short-cycle operating mode, the symbol ?
flashes.
1. Press the "?" key.
The message Operation assured when the restart temperature
will be reached is displayed.
This message is not an error message but an item of
information.
7.2
Messages (Code type Bxx or Mxx)
In the case of failure, the control panel displays a message and a
corresponding code.
1. Make a note of the code displayed.
The code is important for the correct and rapid diagnosis of the
type of failure and for any technical assistance that may be
needed.
2. Switch the boiler off and switch back on.
The boiler starts up again automatically when the reason for the
blocking has been removed.

Energy savings
8.1
Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated.
4 Do not block ventilation outlets.
4 Do not cover the radiators. Do not hang curtains in front of the
radiators.
4 Install reflective panels behind the radiators to prevent heat
losses.
4 Insulate the pipes in rooms that are not heated (cellars and lofts).
4 Close the radiators in rooms not in use.
4 Do not run hot (or cold) water pointlessly.
4 Install a water-saving shower head to save up to 40 % energy.
4 Take showers rather than baths. A bath consumes twice as much
water and energy.
8.2
Recommendations
The remote control is available in the following versions:
4 Wire
4 Radio
The setting of the control panel and/or of the remote control has a
considerable influence on energy consumption.
A few tips:
4 In the room in which the room thermostat is installed, it’s advised
not to use thermostatic valve radiators. If a thermostatic valve is
used the valve must be fully opened.
4 Completely closing and opening thermostatic valve radiators
causes undesirable temperature fluctuations. Open and close
thermostatic valves in small steps.
4 Lower the temperature to around 20°C. This reduces heating costs
and energy consumption.
4 Lower the temperature when you air the rooms.
4 When setting a time schedule , bear days when you are absent
and holidays in mind.

in the buyer’s country.
Starting from the purchase date shown on the original installer’s
invoice, your appliance has a contractual guarantee against any
manufacturing defect.
The length of the guarantee is mentioned in the price catalogue.
The manufacturer is not liable for any improper use of the appliance

The warranty is limited to the exchange or repair of such parts as have
been recognised to be faulty by our technical department and does
not cover labour, travel and carriage costs.
The warranty shall not apply to the replacement or repair of parts
damaged by normal wear and tear, negligence, repairs by unqualified
parties, faulty or insufficient monitoring and maintenance, faulty
power supply or the use of unsuitable fuel.
Sub-assemblies such as motors, pumps, electric valves etc. are
guaranteed only if they have never been dismantled.

The energy efficiency of the package of products provided for in this fiche may not correspond to its actual energy efficiency once installed
in a building, as this efficiency is influenced by further factors such as heat loss in the distribution system and the dimensioning of the
products in relation to building size and characteristics.
