Electrical connection
The electrical connection must be
made by an authorized installer in ac-
cordance with the applicable national
and local standards and regulations.
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.
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
mounted 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
connections 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).

Air intake connection (3)
The air intake can be connected in
case of room sealed installation. The
cover (3) must be disassembled in
order to connect the air intake piping to
the connector inside the boiler. The
diameter should be calculated
according to the national regulations,
together with the flue gas system. The
total resistance of both systems should
never overcome the maximum
permissible resistance of the fan inside
the boiler (see also chapter: Technical
data).
11
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
