Set-up and installation
●
Remove the thermal insulation in the following order:
– Pull the side insulating element off horizontally (fig. 4-13,
item A).
– Pull the rear insulating element off horizontally (fig. 4-13,
item B).
– Pull the front insulating element off horizontally (fig. 4-13,
item C).
●
As required:
Remove the bottom thermal insulation in the
following order:
– Pull the side insulating element off vertically (fig. 4-14,
item A).
– Pull the rear insulating element off vertically (fig. 4-14,
item B).
4.5 Air/flue gas system (LAS)
4.5.1 General instructions for the flue gas system
Minimum requirements
For the design and measurement of the flue gas system, the
country-specific regulations and EN 15287 must be observed.
Basically, any flue gas pipe in accordance with EN 14471 with CE
mark can be used for the flue gas system (equipment type C
63
if
applicable) that meets the following minimum requirements:
– Suitable for gas.
– Suitable for flue gas temperatures of at least 120 °C (temper-
ature class T120 or higher).
– Suitable for at least 200 Pa overpressure (pressure class P1
or H1).
– Humidity-resistant (condensation resistance class W).
– Sufficiently corrosion-resistant (corrosion resistance class 1
or 2).
The properties of the flue gas system must be identifiable on the
installed system (nameplate in the installation room).
The associated assembly instructions must be observed for in-
stalling the flue gas and supply air holding system components or
their means of attachment.
–
Each flue gas line must be installed with a suitable test
adapter for checking and setting the combustion values.
The ROTEX LAS construction sets each include a test
adapter (
D8PA,
15 50 79.00 93
).
– Depending on the local building regulations, inspection com-
ponents must be installed in the required locations.
Type of connections
– Directly on the rear (fig. 4-1:
SET H,
15 50 79.08
).
– At the side on the rear (fig. 4-2:
SET K,
15 50 79.09
).
– Direct roof penetration (fig. 4-7, variant 2 and 3:
SET L,
15 50 79.10
).
For further details and connection dimensions for the three var-
iants of the flue gas pipe, see chap. 4.5.3.
Installation position and piping height
– The maximum permitted flue gas counter pressure is
200 Pa
.
The pressure loss in the supply line must not exceed
50 Pa
.
– Angle of entry of the flue gas pipe into the chimney or instal-
lation shaft:
at least 3°
.
– Avoid horizontal sections in the connection line or keep them
as short as possible.
– Slope for horizontal sections of the flue gas line:
at least 3°
.
Counter-slopes
are
not permissible
at any point in the flue
gas line so that condensate can drain off without restriction.
– If the more than 3 deflections >45° are needed for the flue gas
line, the maximum height for the flue gas line reduces by at
least
1 m per deflection
(flue gas calculations may be
needed).

Fig. 4-14 Removing the bottom thermal insulation
The thermal insulation is installed in reverse order.
WARNING!
There will be a
risk of poisoning
caused by flue gas escaping
within enclosed rooms that are inadequately ventilated.
●
Install only approved flue gas systems.
●
The stipulated ventilation and rear ventilation must be
ensured depending on the installation variant.
●
Coverings are not permissible over the flue gas mouth.
