Switch off the appliance.
Open the windows.
Evacuate the premises.
Contact a qualified professional.
Caution
Do not neglect to service the boiler. Contact a
qualified professional or take out a maintenance
contract for the obligatory annual servicing of the

Recommendations
Caution
The system must satisfy each point in the rules
(DTU, EN and others, etc.) that govern works and
interventions in individual homes, blocks of flats
or other buildings.
Note
Keep the boiler accessible at all times.
Caution
Install the boiler in a frost-free environment.
Note
Regularly check the presence of water and pres­
sure in the heating installation.
Important
Never remove or cover labels and data plates af­
fixed to the appliances. Labels and data plates
must be legible throughout the entire lifetime of
the appliance.
Damaged or illegible instructions and warning
stickers must be replaced immediately.
Important
Remove the casing only to perform maintenance
and repair work. Put the casing back in place af­
ter maintenance and repair work.

Important
Insulate the pipes to reduce heat losses to a mini­
mum.
Caution
Have the boiler and heating system drained by a
qualified professional if the home is left empty for
a long period of time and there is a chance of
frost.

Frost protection
Caution
The frost protection function does not work if the boiler is powered
off.
Caution
The integrated protection system only protects the boiler, not the
heating system.
Caution
Have the boiler and heating system drained by a qualified profes­
sional if the home is left empty for a long period of time and there
is a chance of frost.
Important
To prevent the radiators and the installation from freezing in pla­
ces where that risk exists (e.g. in a garage or an equipment room),
we recommend the connection of an outside temperature sensor
to the boiler.
If the temperature of the water in the boiler falls too much, the integrated
protection device switches itself on. This device functions as follows:
If the water temperature is lower than 7°C, the circulation pump starts
up.
The water temperature is lower than 4°C, the boiler starts up and
switches off when the water temperature is above 35°C.
If the water temperature is higher than 10°C, the boiler shuts down and
the circulating pump continues to run for a short time.

9.1
Maintenance
General
We recommend having the boiler inspected and serviced at regular inter­
vals.
Caution
Do not neglect to service the boiler. Contact a qualified professio­
nal or take out a maintenance contract for the obligatory annual
servicing of the boiler.
Failure to service the appliance voids the warranty.
Caution
Have an inspection carried out and the flues swept at least once a
year or more, depending on the regulations in force in your coun­
try.
Caution
Only qualified professionals are authorised to carry out mainte­
nance work on the boiler and the heating system.
Caution
After maintenance or repair work, check the entire heating system
to ensure that there are no leaks.
Caution
Only genuine spare parts may be used.
9.2
Maintenance instructions
9.2.1
Check the hydraulic pressure
1. Check the hydraulic pressure in the installation.
Caution
If the hydraulic pressure is lower than 0.08 MPa (0.8 bar), more
water should be added. Top up the water level in the heating in­
stallation to reach a hydraulic pressure of between 0.15 and 0.2
MPa (1.5 and 2.0 bar).
2. Carry out a visual check for any water leaks.
9.2.2
Topping up the installation with water
1.
2.
3.
4.
5.
Open the valves on all radiators connected to the heating system.
Set the room thermostat to as low a temperature as possible.
Put the boiler in shut-down/frost protection mode.
Open the fill valve.
Close the filling valve when the pressure gauge shows a pressure of
0.15 MPa (1.5 bar).
6. Put the boiler in heating mode.
7. When the pump has stopped, vent again and top up the water pres­
sure.
Note
Filling and venting the installation twice a year should be sufficient
to obtain an adequate hydraulic pressure. If it is often necessary
to top up the installation with water, contact your installer.

Venting the installation
Venting the installation
Any air in the appliance, the pipes or the valves must be removed in order
to prevent annoying noises that may occur during heating or when tapping
water. Proceed as follows:
1
1.
2.
3.
4.
5.
6.
7.
Open the valves of all the radiators connected to the installation.
Set the room thermostat to the highest possible temperature.
Wait until the radiators are warm.
Switch off the boiler.
Wait approximately ten minutes, until the radiators feel cold.
Vent the radiators. Work from the bottom to the top.
Open the venting valve with the bleed key, keeping a cloth pressed
against the vent.
8. Wait until water comes out of the venting valve and then close the
venting valve.

Warning
The central heating water may still be hot.

9. Switch the boiler on.
A three-minute venting cycle is performed automatically.
10. After venting, check that the water pressure in the installation is still
adequate.
5
Important
If the water pressure is lower than 0.8 bar, the water must be top­
ped up. If necessary: top up the central heating installation (rec­
ommended water pressure between 1.5 and 2.0 bar).

Energy savings
Energy-saving advice:
Do not block ventilation outlets.
Do not cover the radiators. Do not hang curtains in front of the radiators.
Install reflective panels behind the radiators to prevent heat losses.
Insulate the pipes in rooms that are not heated (cellars and lofts).
Close the radiators in rooms not in use.
Do not run hot (or cold) water pointlessly.
Install an energy-saving shower head, which can save up to 40 % ener­
gy.
Take showers rather than baths. A bath consumes twice as much water
and energy.

12 Warranty
12 Warranty
12.1
General
We would like to thank you for buying one of our appliances and for your
trust in our product.
In order to ensure continued safe and efficient operation, we recommend
that the product is regularly inspected and maintained.
Your installer and our service department can assist with this.
12.2
Terms of warranty
The following provisions do not affect the application, in favour of the buy­
er, of the legal provisions with regard to hidden defects that are applicable
in the buyer's country.
This appliance comes with a warranty that covers all manufacturing faults;
the warranty period will commence on the date of purchase stated on the
installer's invoice.
The warranty period is stated in our price list.
As a manufacturer, we can by no means be held liable if the appliance is
used incorrectly, is poorly maintained or not maintained at all, or is not in­
stalled correctly (it is your responsibility to ensure that installation is carried
out by a qualified installer).
In particular, we cannot be held liable for material damage, intangible los­
ses or physical injury resulting from an installation that does not comply
with:
Legal or regulatory requirements or provisions laid down by the local au­
thorities.
National or local regulations and special provisions relating to the instal­
lation.
Our manuals and installation instructions, in particular in terms of regular
maintenance of the appliances.
Our warranty is limited to the replacement or repair of the parts found to
be defective by our technical services team, excluding labour, transfer and
transport costs.
Our warranty does not cover replacement or repair costs for parts that may
become defective due to normal wear, incorrect usage, the intervention of
unqualified third parties, inadequate or insufficient supervision or mainte­
nance, a mains supply that is not appropriate or the use of unsuitable or
poor quality fuel.
Smaller parts, such as motors, pumps, electrical valves etc., are guaran­
teed only if these parts have never been dismantled.
The rights established in European Directive 99/44/EEC, implemented by
legal decree No. 24 of 2 February 2002 and published in Official Journal
No. 57 of 8 March 2002, remain in force.

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.

The factor for weighting the heat output of preferential and supple­
mentary heaters of a package as set out in the following table.
The value of the mathematical expression: 294/(11 · Prated),
whereby ‘Prated’ is related to the preferential space heater.
The value of the mathematical expression 115/(11 · Prated),
whereby ‘Prated’ is related to the preferential space heater.
