Recommendations
If- Doyounotsmellusegas:
a bare flame, do not smoke, do not actuate
electrical contacts or switches ( doorbell, light, motor, lift,
etc..),
- Cut the gas supply,
- Open the windows,
- Extinguish all flames,
- Evacuate the premises,
- Consult your fitter or the maintenance company,
- Inform the gas supplier.
the event of flue gas emanation:
In- Switch
the boiler off,
- Open the windows,
- Evacuate the premises,
- Consult your fitter or the maintenance company.
Advised positions: Boiler
- It is forbidden to store inflammable products and
materials in the boiler room or close to the boiler, even
temporarily,
- MCR boilers must be installed in a frost-free environment,
- The boiler's ignition device must always be accessible.
Temperature:
- The tap water temperature is factory set at 55°C; this
temperature can be set to 65°C
- The maximum temperature that the water can reach in the
boiler is 95°C. The temperature in the radiators can reach
the maximum value programmed for the boiler,
- When the boiler is operating, the discharge conduit may
reach a higher temperature.
Maintenance: We recommend doing this at least once a year
Maintenance and cleaning of the heater must be carried out at
least once a year by a qualified technician.
Installation, commissioning, maintenance and repairs must be
carried out by authorised specialists (approved heating
engineers / installers).
For a proper operating of the boiler, follow carefully the
instructions.

Aeration
France: the cross section of the aeration vent, which is compulsory
in the premises in which the boiler is installed, must comply with the
DTU 61.1 (P 45 204) standard and, in particular, with the instruction
on general improvement work (Book 1764 April 1982).
Belgium:the cross-section of the aeration vents, which are
compulsory in the room in which the boiler is installed, must comply
with the NBN B 61-002,NBN D 51-003,NBN D 51-006 standard.
air inlet into the premises must in no event be
The
obstructed, even partially.
Maintenance
The boiler must be serviced and fully cleaned and the flue gas
conduit swept by a qualified professional at least 1 times per year.
We recommend that you take out a maintenance contract.
Precautions against frost
MCR boilers must be installed in a frost-free environment.
If the temperature of the central heating water in the boiler falls too
much, the integrated protection device switches itself on:
- If the water temperature is lower than 7°C, the circulating pump is
activated,
- If the water temperature is lower than 3°C, the boiler is activated,
- When the water temperature is above 10 °C, the boiler is switched
off and the circulation pump runs for another 15 minutes.

- To confirm, press the l key.
- Press key 1 time to return to the current operating mode.
-
In ECO mode: I
If the ECO mode is set to I, when the boiler is used with an
external hot water tank, the water is not heated. If the hot water
tank is empty, the tap water will therefore be cold.
In ECO mode: Auto
If the setting is on Auto and the control unit is fitted with a ECO
function, the appliance adapts to the control unit setting.
For example: The ECO setting is tripped at night during reduced
temperature operation.

- Open the valves on all radiators connected to the heating system.
- Set the room thermostat to as low a temperature as possible.
Wait until the temperature drops below 40°C and the radiators seem
cold before filling the central heating system.
Ensure that the boiler is switched off.
When filling the system, use the disconnecteur.

- Open the valve (1/4 turn).
- Close the disconnecteur when the manometer indicates a
pressure of 2 bar.
- Fill the low flow heating circuit using the drainage tap in order to
favor the bleed.
- When the pump has stopped, bleed again and top up the water
pressure.
Filling and bleeding the installation 2 times 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 fitter.
- Reset the boiler.

- Switch on the boiler. A bleed cycle of a duration of around 3
minutes is carried out automatically.
- Wait until water comes out of the bleed valve and then close the
bleed connection.
The water may still be hot.
- Check regularly that the installation contains water and is
pressurised. Add water to the installation if necessary.

Draining the heating circuit
It may be necessary to drain the boiler if the radiators have to be
replaced in the event of significant leakage or danger of frost.
- Open the valves on all radiators connected to the heating system.
- Connect a hose and open the drainage valve at the lowest point of
the installation.
The water may still be hot.
- Set the room thermostat to as low a temperature as possible.
- Switch the boiler off.
- Open the bleed connection using the bleed key provided whilst
keeping a rag pressed against the connection. If water continues
to escape, close the connection and try again later.
- The radiators are cold.
- Open the valves on all radiators connected to the heating system.

MCR boiler off
Boiler without antifreeze protection
Before any work is carried out on the equipment / heating system, the
power supply must be disconnected (by means of the appropriate
fuse or main switch, for example) and warning must be given before
any reconnection.
In the event of prolonged absences (weekend, holidays): Switch the
boiler off.
Boiler with antifreeze protection
If the central heating system is not used for a long period, we
recommend switching the boiler off.
LTALW7H000217a
- Set the room thermostat or the regulator: for example 10 °C.
- Close the gas valve.
- Define parameter P4 as 1 (energy-saving mode); the heat
retention function will be deactivated.
The boiler will then only start up to protect itself from frost.

approx. 3 minutes) and will do this every time the power supply is
isolated. The version numbers are displayed alternately.
- The display shows :
- 1: Ventilation
- 2: Ignition
- 4: Only domestic hot water operating
- 7: Boiler pump operating for DHW heating

Maintenance and periodic checks
- Open and close the radiator valves several times a year (this
prevents the valves from seizing up).
- Checking the hydraulic pressure. Insufficient pressure: add water
(1.5 - 2 bar).
- Clean the outside of the boiler using a damp cloth and a light
detergent.
and cleaning of the heater must be carried out
Maintenance
at least once a year by a qualified technician.
We recommend taking out a maintenance contract.
- Carry out a visual check for the presence of any water leaks.
