10.1 Prepare the Dry Line Wall section as shown. Two layers of fire board either side of the metal track
forming the aperture and line with a single layer of fire board.
10.2 Using threaded drop rods of the correct length affixed to the underside of the slab/soffit, pass the
other end through the damper cleat hole to provide support prior to fitting the fire batt into position.
See Fig.12 for general connection detail.
10.3 Ensure the damper is level and will align with any connecting ductwork.
10.4 Ensure that all connecting edges including the perimeter of the fire batt and between the AF return
and fire batt have Fire Pro glue applied as directed by the manufacturers directions.
10.5 The Fire Batt is better to be slightly over sized that allows for a firm push into place, than fitted
loosely.
10.6 Once the Fire Batt has been fitted, apply a 10-15mm bead of Rockwool FirePro acoustic
intumescent sealant around the perimeter on both sides. please see Fig. X.
10.7 It is preferable to allow the intumescent sealant to cure before connecting any ductwork.
10.8 Ensure that the Thermal Fuse that is wired into the fitted actuator remains protected until fitted into
the ductwork.
