4.2.1

Gas/air regulation

The boiler is equipped with a casing that also serves as an air box. The
fan draws in the combustion air. The gas is injected into the venturi and
mixed with the combustion air. The fan speed is controlled on the basis of
the settings, the heat demand and the prevailing temperatures measured
by the temperature sensors. The gas/air ratio control ensures an accurate
mixture of the required amounts of gas and air. This provides optimum
combustion over the entire heat input range. The gas/air mixture goes to
the burner, where it is ignited by the ignition electrode.
Important
The combustion air supply is checked before each burner start,
and at least once every 24 hours. During continuous operation
(e.g. supplying process water), please note that the boiler control
will reset every 24 hours.
4.2.2

Combustion

The burner heats the central heating water flowing through the heat ex­
changer. If the temperature of the flue gases is lower than the dew point
(approx. 55°C), the water vapour condenses in the heat exchanger. The
heat released during this condensation process (referred to as the latent
or condensation heat) is also transferred to the central heating water. The
cooled flue gases are discharged through the flue gas discharge pipe. The
condensed water is discharged through a siphon.

Control system

®
The eSMART electronic control system ensures that your heating system
is smart and reliable. This means that the boiler responds practically to
negative environmental influences (such as limited water flow and air flow
problems). In the event of such influences, the boiler will not go into lock­
out mode, but in the first instance will modulate back. Depending on the
nature of the circumstances, a warning, control stop or lock-out may occur.
The boiler continues to supply heat provided the situation is not danger­
ous. With this control system, your boiler is also equipped for remote con­
trol and monitoring.
