Installation procedure
Mount the metal posts and the wall in accordance with the
specifications of the wall manufacturer and the required ex-
change parts as shown on Figure 21. Leave a recess for in-
stalling the BKP-EN with mounting frame type ER-P1 (pos.
17).
Construct a circumferential reveal (pos 20.1) with 20 mm
plasterboards and screw them centrally to the circumferen-
tial metal profile frame (pos. 19.1 - fastening: e.g. drywall
screws ø 3.5 x 35 mm, screw distance ≤ 250 mm, but at least
2 screws per side).
Insert the BKP-EN into the wall recess, so that the stop of
the installation frame type ER-P1 contacts the wall (operat-
ing side – observe installation dimension of 200 mm up to
ER-P1 or 210 mm up to the front edge of the wall). Average
out the circumferential annular gap evenly between the re-
veal recess and the installation frame type ER-P1. Mount
the BKP-EN with the help of mounting suspensions, etc.
The fire damper is fastened to the supporting structure (ex-
change profiles - pos. 10.1) on the B sides (top and bottom)
using two fixing lugs each (pos. 18; 4 per damper). The fixing
lugs are fastened to the supporting structure using 2 drywall
screws for each lug (pos. 19.2, e.g. ø 5.5 x 90 mm).
Mounting aids (suspension, wedges, etc.) must be removed
(fixing lugs are no installation and mounting aids and must
remain mounted).

37 Double-board layer (gypsum-bonded wall boards, d=20
mm, b=60 mm). Fastening: Dry-wall screws, for example,
ø 5.5 x 90, a ≤ 200 mm, but at least 2 screws per side,
connection and butt joints of the double-board layer
must be filled with the wall material.
