Models and output
The floor standing gas condensing
boiler R3456 EVO is available in 3
different ranges R3400 EVO, R3500
EVO and 3600 EVO. R3400 EVO is
the low condensing series. It consists of
10 models covering an output range
from 650 up to 1.900kW.
The R3500 EVO series consists of 9
models and covers an output range of
650 up to 1.600kW with an excellent
efficiency of 103,7%.The R3600 EVO
series offers maximum output with the
highest efficiency. 10 models cover an
output range of 700 up to 2.000kW with
an efficiency up to 109,1%.
Application possibilities

Gas condensing boiler R3456 EVO
Technical description
Technical Description
The R3456 EVO is a fully modulating
condensing boiler. The control unit of
the boiler adapts the modulation ratio
automatically to the heat demand re-
quested 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 there-
with the best efficiency. The flue gases
created by the combustion are trans-
ported downwards through the boiler
and leave at the back side into the
flue system.
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, leaving the boiler at the top
(burner) section. The cross flow work-
ing principle (water up, flue gas down)
ensures the most efficient results.
The LMS14 control unit can
control the boiler operation based
on:
 Fixed flow temperature;
 weather compensated
operation (with optional
outdoor sensor);
 0-10V external influence
(temperature or capacity) from
a building management
system.

Extent of delivery
Standard boiler
Boiler transport
Boiler installation
Boiler installation
The boiler should be positioned in a frost-proof boiler room. If the boiler
room is on the roof, the boiler itself may never be the highest point of the
installation.
When positioning the boiler, please note the recommended minimum
clearance in the picture. When the boiler is positioned with less free space,
maintenance activities will be more difficult.
Standard boiler
A boiler delivery package contains the following components:
Component Pcs. Package
Boiler fully assembled and tested 1On wooden pallet, sealed in PE foil
Syphon + dirt seperator for condensate connection 1Cardboard box on top of heat exchanger
(under casing)
Operation and Installation manual 1On inside of front panel
Boiler transport
Whenever necessary, the boiler can be dismantled into
smaller parts for easier transport inside the building.
The table below shows the main dismantled parts with
their weight and dimensions.
Once the boiler is in the correct position, turn anti-clockwise the regulator (A) or the nut
(B) to let the feet out, till the boiler is set in the right height. Ensure that the wheels are
not in contact with the floor!
Water and gas connections should be done after adjusting the feet, as they affect the
exact height of all connections.
The (inter)national and local norms for the installation of heating systems should be
respected at all times.
