Frost Protection
If the central heating system is not in use and there is a risk of frost, we
recommend activating the boiler's antifreeze protection function.
Caution
The frost protection does not work if the boiler is switched off.

5 Utilisation with the control panel B-Control
1. Put the boiler in frost protection mode. The standby function will be
deactivated.
The boiler will then only start up to protect itself from frost.
Note
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.
If the water temperature is lower than 4°C, the boiler starts up.
If the water temperature is higher than 10°C, the boiler shuts down and
the circulation pump continues to run for a short time.

Frost Protection
If the central heating system is not in use and there is a risk of frost, we
recommend activating the boiler's antifreeze protection function.
Caution
The frost protection does not work if the boiler is switched off.
Caution
The integrated protection system only protects the boiler, not the
heating installation
Caution
If the home is unoccupied for a long period and there is a risk of
frost, drain the boiler and the heating system.
1. Put the boiler in frost protection mode. The standby function will be
deactivated.
The boiler will then only start up to protect itself from frost.
Note
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.
If the water temperature is lower than 4°C, the boiler starts up.
If the water temperature is higher than 10°C, the boiler shuts down and
the circulation pump continues to run for a short time.

Maintenance
9.1
General
We recommend having the boiler inspected and serviced at regular inter
vals.
Boiler maintenance and cleaning must be carried out at least once a
year by a qualified professional.
Have an inspection carried out and the flues swept at least once a year
or more, depending on the regulations in force in your country.
Caution
Failure to service the appliance voids the warranty.
Caution
Maintenance work must be carried out by a qualified professional.
Caution
Only genuine spare parts may be used.
9.2
Maintenance instructions
1. Check the hydraulic pressure in the installation.
Fig.53
Beware of water leaks
Note
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.
3. Open and close the radiator valves several times a year. This helps
to prevent the valves from seizing up.
4. Clean the outside of the boiler using a damp cloth and a gentle de
tergent.
AD-0001507-A
9.2.1 Checking the water pressure
The water pressure must be a minimum of 0.08 MPa (0.8 bar).
1. If necessary, top up the water in the heating system.
The recommended water pressure when cold is between 0.10 MPa
(1.0 bar) and 0.15 MPa (1.5 bar).
9.2.2 Topping up the installation with water
If necessary, top up the water level in the heating system (recommended
hydraulic pressure between 0.15 and 0.2 MPa (1.5 and 2 bar)).
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.

13 Energy savings
13 Energy savings
Tips on saving energy:
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).
Turn off the radiators in rooms not being used.
Do not run hot (or cold) water pointlessly.
Install a water-saving shower head to save up to 40% energy.
Take showers rather than baths. A bath consumes twice as much water
and energy.
