Installation above roof, round hood, stay plate
After making a hole in the roof, inspect the surface
and make sure that the stay plate is supplied with a
load-bearing, stable attachment. If not, build a frame
for attachment.
Install the lower half of the stay plate (the part with-
out the folded up edge). Solder the chimney and then
secure it to the roof.
Cut a hole in the roofing felt and insert the upper half
of the stay plate. This is done to prevent condensation
running out into the roof structure. Secure it to the
roof.
Then build a frame around the bottom fitting’s con-
necting piece at the same height as the roofing.
Return the cornice and then the roofing.
Thread the roof seal over the chimney module, and
lower it carefully towards the roofing tiles (so that
the system chimney’s paintwork does not sustain any
damage).
Continued: See pages 23-24, depending on roofing.

The cone
If the cone’s opening does not correspond with the
roof angle, cut it horizontally before screwing the
cone/roof seal into place.
Thread the roof seal
over the chimney
module, and lower
it carefully towards

chimney’s paintwork
does not sustain any
damage).
