Vertical pitched and flat roof outl et, parallel, system size Ø 80/80 mm
&
For installing the Vitopend in an attic (type C
32x
)
&
The roof outlet may only be used, where the ceiling of the occu-
pied room also forms part of the roof or only the roof structu re is
located above the cei ling (pi tched atti c).
&
When the balanced flue system is routed through roof spaces,
which are not used as accommodation, run the balanced flue
pipe through an additi onal metal pipe as protection against
mechanical damage (TRGI '86/96, point 5.6.1.2).
&
It may also be routed behind a jamb wall or a solid wall of an
attic built as accommodation, if the fire protection class of the
jamb wall corresponds to that of the ceiling (e.g. B30).
It was verified as part of the DIN DVGW type test, that nowhere
on Vitopend or the balanced flue system will surface tempera-
tures higher than 40 K above room temperature occur.
&
Minimum clearances to combustible materials inside the instal-
lation location or in connection with the roof outl et do not have
to be observed.
