Electrical connection
The electrical connection must be ma-
de by an authorized installer in
accordance with the applicable national
and local standards and regulations.
For the power supply it's necessary to
use a mains isolator switch with a con-
tact opening of at least 3 mm
within the boiler room. This switch can
be used to switch off the power supply
for maintenance purposes.

Gas connection (1)
3
The gas connection must be made by
an authorized installer in accordance
with the applicable national and local
standards and regulations.
Connect the gas line from the system
tension free to the gas connection (1) of
the boiler. A gas cock should be moun-
ted directly behind the boiler.
A gas filter can be mounted directly on
the gas connection of the boiler.
Flue gas connection (7)
Regulations for the construction of flue
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:
All cables should be lead through the
cable glant (2) from the back of the
boiler boiler into the electro panel
(11).
Connect all wires to the terminals
according to the wiring diagram of the
boiler (enclosed in map attached to
back panel of the boiler).
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 (3)
The air intake can be connected in ca-
se of room sealed installation. The co-
ver (3) must be disassembled in order
to connect the air intake piping to the
connector inside the boiler. The diame-
ter should be calculated according to
the national regulations, together with
the flue gas system. The total resistan-
ce of both systems should never over-
come the maximum permissible resis-
tance of the fan inside the boiler (see
also chapter: Technical data).
