recommendations

2.1 Safety instructions

DANGER

If you smell gas:

1. Do not use a naked flame, do not smoke, do not
operate electrical contacts or switches ( doorbell,
light, motor, lift, etc..).

2. Shut off the gas supply.

3. Open the windows.

4. Evacuate the premises.

5. Call your fitter.

DANGER

If you smell flue gases:

1. Switch the appliance off.

2. Open the windows.

3. Evacuate the premises.

4. Call your fitter.

WARNING

Depending on the settings of the appliance:

4 The temperature of the flue gas conduits may exceed

60°C.

4 The temperature of the radiators may reach 85°C.

4 The temperature of the domestic hot water may reach

65°C.

CAUTION

Do not neglect to service the appliance:
4 For completely safe and optimum operation, you

must have your boiler regularly serviced by an
approved installer.

3 Description

3.1 Operating principle

3.1.1. Gas/air setting

The casing fitted to the boiler is also used as an air box. Air is sucked
in by the fan and gas injected into the venturi by the fan intake. The
fan rotation speed is set according to the settings parameters, the
thermal energy requirement and the temperatures measured by the
temperature sensors. The gas and air are mixed in the venturi. The
gas/air ratio ensures that the quantities of gas and air are adjusted to
each other. This provides optimum combustion on the entire output
range. The gas/air mixture is fed into the burner on top of the
exchanger.

3.1.2. Combustion

The burner heats the heating water circulating in the heat
exchanger. At a return temperature lower than around 55°C, the flue
gases cool down to a temperature lower than the dew point, thus
causing the condensation of the water vapour contained in the flue
gases in the lower section of the heat exchanger. The heat released
during this condensation process (the latent heat or condensing heat)
is also transferred to the heating water. The cooled combustion gases
are evacuated via the combustion gas outlet flue. The condensation
water is evacuated via a siphon.
