Installation
Connecting the water heater
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 water heater,
use flue gas 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:
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
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.
