Mark out the hole to be cut on onesurface of the wall, using the centre ofthe duct run as a datum. Check thediagonals of the marked out rectangle toensure that it is square.2. Drill the four corners to project therectangle on to the reverse side of thewall. Mark out the hole on the reverse.3. Cut the top and bottom edges of thehole first, then the vertical edges. Do thesame on the reverse.4. Remove the waste material and tidy upall the edges of the hole.5. Frame out the sides of the hole withstudding as used in the wall construction.6. Line the sides of the hole using thesame plasterboard as used in the wallconstruction.DWFX-F with Smoke/Shield*7. Drill clearance holes in the damperflange marking out such that anyfasteners used will pass through theboard materials and penetrate thestudding behind. Centres should beapproximately 150mm.8. Place the damper in the hole in thewall. Use some pieces of plasterboard asshims to ensure that the damper isequally positioned in the hole. Push theflange flush to the face of the wall.
