-MOUNTING PLATE INSTALLATION
1.Separate toggle bolts from toggle nuts.
2.Insert one toggle bolt into each hole on the mounting plate (these holes correspond to holes A, B, C and D of the Wall Template) and put toggle nut onto the toggle bolt (Fig. 13). If hole is located in a stud, do not use toggle bolt.
3.If using horizontal exhaust follow these two (2) steps. If method other than horizontal continue to step 4.
1.Attach Backdraft Damper assy. to the back of mount-
ing plate with 2 tapping screws provided for
OUTSIDE VENTILATION, Horizontal Exhaust (Fig. 14).
2.Connect the Backdraft Damper assy. to the horizon-
tal duct. Insure that Backdraft Damper plate is allowed to move freely. (See Fig. 14a).
4.Insert nut and bolt through the hole in the wall with toggle nut closed (Fig. 15).
NOTE: Before you do this, be sure you leave space at least the thickness of the wall between the mounting plate and the end of toggle nut (in closed posi- tion). If you do not leave this space, toggle nut will not open on the other side of wall.
5.Turn toggle bolt clockwise to tighten (Fig. 15a).
6.Secure mounting plate to a minimum of one stud with a wood screw provided.
