Assembly of wall cowl
Assemble wall cowl on a surface which is as flat as possible
and which is exposed to wind from all directions. Drill an
opening (8) measuring 70 mm in diameter (pack wood into
hollow spaces in the area of the cowl opening). Use the pro-
vided rubber seal (10) for sealing. In the event of structured
surfaces, coat with plastic body sealant – do not use silicone.
In the event of a greater wall thickness, first connect the
exhaust double duct to the cowl from the outside.
Slide rubber seal (10) and clamp (4) onto the cowl inner
part (11).
Press end of ex-haust duct (1) together so that winding
touches winding, slide over the O-ring (2a) on the connection
fitting (2) up to the collar (3 – cowl bend pointing upward) and
tighten clamp (4) in such a way that the knurled edge of the
clamp encloses the collar.
