Assembly of deck
cowl
Fig. B, C and D: Assemble
deck cowl on as flat a surface
as possible, which is exposed
to wind from all directions.
Drill an opening of 80 mm
diameter. Sealing is car-
ried out using the enclosed
cellular rubber seal (1)
without any further sealing
compound.
In the case of greater roof
thick-nesses, first connect
the ducts to the cowl from
the outside.
Pass cellular rubber seal (1)
and clamp (2) over the ducts.
Press together the end of
the exhaust duct (3) so that
winding touches winding and
slide over the O-ring onto the
connection fitting (4).
Fasten using clamp (2) in
such a way that the bead
edge of the clamp grasps
around the collar. Slide com-
bustion air intake duct (6)
over the connection fitting (5)
and fasten with clamp (11).
Fasten cowl part (7) with
screws (8). Screw on cowl
cover (9) with 3 bolts (10).
