Vertical outlet for pitched or flat roofs
If the balanced flue system is routed
through roof spaces that are not used
as accommodation, run the flue through
an additional metal pipe as protection
against mechanical damage
(TRGI 2008).
When several roof outlets are installed
side by side: Observe a minimum clear-
ance of 1.5 m between outlets and to
other building structures (e.g. skylights)
in accordance with TRGI 2008.
Observe the clearance of the flue outlet
above the roof (see diagram). If the
rated heating output is ≥ 50 kW, an
above-roof extension is required (see
page 46).
