Models and output
The wall hung gas condensing boiler
R40 is available in 5 types within an
output range from 61 until 132 kW.
Application possibilities
The gas condensing boiler R40 is
appli
cable for all central heating
systems
built according to EN12828.
In cascade applications (max. 8 boilers
with LMS14 master/slave cascade
control) the R40 can cover installations
up to 1026 kW.
Preferred applications are central hea-
ting and sanitary hot water production
in multi-family buildings, municipal and
industrial buildings.

Description
The R40 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
mix
ing system will adapt the gas ratio to
the chosen fan speed, in order to
main
tain the best possible combustion
fig
ures and therewith the best efficiency.
The flue gases created by the
combus
tion are transported downwards
through the heat exchanger and leave
the boiler at the top 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
heat exchanger, in order to leave the
boiler at the flow connection. The cross
flow working principle (water up, flue
gas down) ensures the most efficient
combustion results.
