Operating principle
The Econoflame R6000 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 Whirlwind
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 chimney
connection.

The return water from the system en-
ters the boiler in the lower section,
where is the lowest flue gas tempera-
ture in the boiler. In this section con-
densation takes place. The water is
being transported upwards through the
boiler, in order to leave the boiler at the
top (burner) section. The cross flow
working principle (water up, flue gas
down) ensures the most efficient com-
bustion results.

The KM628 control unit can control the
boiler operation based on:
•
fixed temperature (stand alone opera-
tion);
•
weather compensated operation (with
optional controller);
•
with 0-10V external influence
(temperature or capacity) from a
building management system.
