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.

4.3 Stopping the boiler
- Cut the power supply to the boiler.
- Close the gas valve.
Don't forget the risk of frost.
4.3.1 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.
4.3.2 Precautions required in the case of long boiler stops (one or more years)
- 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.
4.4 Commissioning the boiler
Initial commissioning must be done by a qualified
professional.
4.4.1 Commissioning
- Ensure that the boiler is switched off
- Remove the front casing
- Open the main gas valve
- Open the boiler control panel (Control panel instructions)
- Check the electrical connection
- Fill the installation with water and check hydraulic tightness (Pmin:
0.8 bar)
- Bleed the heating installation
- Fill the condensates siphon with water
- Check the connection of the combusted gas evacuation and the air
inlet
- Empty the gas inlet
- Open the gas valve on the gas pipe to the boiler
- Check the gas connection
- Turn the boiler on
- Turn the main switch to 8
- The boiler type is displayed on the screen for 5 seconds
- Provoke a heating request
- The boiler starts to operate
- Check the settings (See "Gas settings" - Installation and Service
Manual). If necessary, correct the settings
5 Checking and maintenance
The boiler is almost maintenance-free if it is set correctly. The boiler
only requires an annual check and cleaning if necessary.
Make the following checks at least 1 time a year:
- Checking the combustion in the boiler
- Setting the ignition electrode
- Checking tightness (hydraulics, combusted gas discharge and
gas)
- Checking the hydraulic pressure
Carry out the following maintenance at least 1 time a year:
- Clean the fan
- Clean the heat exchanger using the tool provided
- Clean the burner
- Clean the siphon.

7 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.
