Connecting the boiler
This chapter will explain how to
make all connections to the boiler
with regard to:
•
Hydraulic connections
•
Condensate drain connection
•
Gas connection
•
Flue gas connection
•
Air intake connection
(under casing)
•
Electrical connection
The boiler should always be con-
nected in such a way, that the sys-
tem applies to all relevant standards
and regulations (European, national
and local). It's the responsibility of
the installer to ensure that all stand-
ards and regulations are respected.
Hydraulic connections
The boiler should always be con-
nected in such a way, that water
flow through the boiler can be en-
sured at all times.
Connect the flow (4) and return
(5) of the boiler tension free to the
system. The (optional) 2nd return
kit allows the boiler to be used in a
system with two return circuits. The
common return becomes the low
temperature return, the 2nd return

connection (6) is the high tempera-
ture return.
The (optional) accessory kit with
safety valve, manometer and deaer-
ator should be mounted on the flow
connection (4) of the boiler, before
connecting to the system.
The (optional) pump kit should be
mounted directly to the return con-
nection (5) of the boiler, before con-
necting to the system.
Condensate connection
The syphon (included in delivery)
should be installed to the connec-
tion at the bottom of the condens
tray (7).
Lead the pipe over the floor (8) and
connect it to the draining system in
the boiler room. The connection to
the draining system should always
be done with an open connection,
in order to avoid a flooding of the
boiler in case of a blocked drain.

Gas connection
The gas connection must be made
by an authorized installer in accord-
ance with the applicable national
and local standards and regulations.
Connect the gas line from the sys-
tem tension free to the gas connec-
tion (1) of the boiler. A gas isolating
valve should be mounted directly
behind the boiler.
A gas filter can be mounted directly
on the gas connection of the boiler.
