■
All current regulations on installing and commission-
ing flue systems have been observed.
■
The manufacturer's instructions for the installation
and commissioning of the electrostatic precipitator
have been observed.
Note
■
Install a flexible connection piece in the flue to pre-
vent sound transmission from the flue gas fan.
Additional on-site sound insulation measures may be
required.
■
Never brick the flue pipe into the chimney.
■
Let the flue pipe connector project about 10 mm into
the chimney. This prevents condensate or rainwater
from the chimney running into the flue pipe.
Flue gas temperatures below 90
º
C can occur during
partial load operation of the boiler.
■
Connect the boiler to a
moisture-resistant chim-
ney
.
■
Install a boiler flue connection with condensate trap
in the flue pipe.

Possible installation location for the draught stabil-
iser (draught limiter)
1.
Install the flue pipe with a rise to the chimney (pref-
erably 45°).
Flue pipe (internal diameter):
7
200 mm
Max. flue pipe length: 3000 mm
2.
The entire flue pipe with cleaning aperture must be
gas-tight.
3.
Thermally insulate the flue pipe, minimum insula-
tion thickness 30 mm.
4.
Install a draught limiter (accessories) in the chim-
ney:

Making the connections on the heating water side
Note
Route water pipes so that all casing panels are acces-
sible and can be removed for maintenance.
Note
Only connect controlled heating circuits with mixer.
