Flue gas connection (7)
Regulations for the construction of flue
7
gas systems are very different for each
country. It should be ensured that all
national regulations with regard to flue
gas systems are respected.
Connect the flue gas system to the flue
gas connection (7) of the boiler, use
fluegas systems with seamless connec-
tions only. It's not necessary to make a
separate condensate drain for the flue
gas system, as the condensate will be
drained via the syphon of the boiler.
Please note the following issues:

It's recommended to use stainless
steel or PPS fluegas systems

The diameter of the flue gas system
must be chosen by calculation ac-
cording to the national regulations

Construct the flue gas system as
short as possible (for maximum
length see planner documentation)

Construct horizonal ways with a mini-
mum angle of 3º
Air intake connection (8)
The air intake can be connected in ca-
se of room sealed installation. The dia-
meter should be calculated according
to the national regulations, together
with the flue gas system. The total re-
sistance of both systems should never
10
overcome the maximum permissible
resistance of the fan inside the boiler
(see also chapter: Technical data).
Electrical connection
The electrical connection must be
made by an authorized installer in
accordance with the applicable
national and local standards and re-
gulations.
For the power supply it's necessary
to use a mains isolator switch with a
contact opening of at least 3 mm
within the boiler room. This switch
can be used to switch off the power
supply for maintenance purposes.
All cables should be lead through the
cable glants (9) at the bottom of the
boiler of the boiler boiler into the elec-
tro panel (10).
Connect all wires to the terminals
according to the wiring diagram of the
boiler, see pages 11-12.
Outside sensor mounting
If an outside sensor (accessory) is
connected to the boiler, the sensor
should be positioned as shown on the
drawing.
