Flue gas data
Parallel boiler connection
The boiler comes as standard with a
parallel connection for the flue gas
outlet and air supply system. For the
air supply opening (1) diameter and
the flue gas outlet connection (2), see
table below.
The air supply channel can be
connected to it, or, if it involves an
“ open device ” (Drainage category B),
an air filter is recommended.
Flue gas connection
We recommend the use of ATAG ’ s com-
prehensive range of flue gas components.
For further information, please see the
installation instructions:
- ATAG wall terminals
- ATAG roof terminals
- ATAG flue pipe components, both indivi-
dual pipes and concentric tubes.
Regulations about the construction and
installation of flue gas systems are diffe-
rent from country to country. It must be
ensured that all national regulations with
regard to chimney systems are observed.
It is not necessary to install a separate
condensate drain for the flue gas system,
since the condensate will be flushed out
via the boiler and into the siphon. Please
observe the following recommendations:
- Only use corrosion - resistant material
- The diameter must be calculated and
selected according to the national regula-
tions.
- The length of the flue gas system must
be kept as short as possible (and must
not exceed the maximum permitted
length, see the documentation for plan-
ners)
- Horizontal flue gas tubes must have an
inclination of at least 3° back towards the
boiler.
Air supply connection
If required, a separate room sea-
led air supply tube may be
connected via the inclusion of the
optional air supply connector fit-
ting. The diameter must be calcu-
lated in conformity with national
regulations and in combination
with the flue gas gas system. The
overall resistance of the air supply
and flue gas tubes may not
exceed the maximum supply pres-
sure of the fan at any time. (Also
see the Chapter
“ Technical data ”)
Concentric boiler connection
The boilers 60 - 70 - 100 - 120 - 140
can be converted into a concentric
connection using the parallel/
concentric adapter 100/150
(optional) and carrying out the
following tasks:
- Open and remove the frontal
panel and the top panel.
- Lift the parallel connection.
- Disconnect the main switch 230V
connection and remove it.
- Replace the parallel connection
with parallel concentric adapter.
- Connect and fit the main switch
230V according to previous confi-
guration.
The XL - F - boilers can be used
both in an “ open ” and in “ closed ”
system.
Open system
The required combustion air is
taken from the immediate environ-
ment (boiler room). For this purpo-
se, please comply with the appli-
cable boiler room ventilation regu-
lations.
When using boiler category B23
and B33 as an
‘ open boiler ’, the
protection degree of the boiler will
be IPX0D instead of IPX4D.
An air filter or a grid is recom-
mended on the air intake of the
boiler (available as an additional
component)
Closed system
The required combustion air is
drawn in from the outside through
a channel. This improves installati-
on possibilities within a building. In
general, outside air is cleaner than
air from the boiler room.
