Operating principle
The R3XXX EVO is a fully modulating
boiler.
The control unit of the boiler adapts the
modulation ratio automatically to the
heat demand requested by the system.
This is done by controlling the speed of
the fan. As a result, the mixing system
will adapt the gas ratio to the chosen
fan speed, in order to maintain the
best possible combustion figures and
therewith the best efficiency.
The flue gases created by the
combustion are transported downwards
through the boiler and leave at the back
side into the flue system.

The return water from the system enters
the boiler in the lower section, where is
the lowest flue gas temperature in the
boiler.
In this section condensation takes place.
The water is being transported upwards
through the boiler, leaving the boiler at
the top (burner) section.
The cross flow working principle (water
up, flue gas down) ensures the most
efficient combustion results.
