2. Insert 5/16" x 1-1/4" bin bolt with neoprene washer through the hole in the side of the roof vent.
Place jamb nut onto the bolt and tighten. (See Figure 8F.)
3. Slide one eyelet of grill guard onto the 5/16" bin bolt.
4. Insert 5/16" x 1-1/4" bin bolt with neoprene washer through the other side of the roof vent, through
jamb nut and other eyelet of grill guard. Tighten nut against vent housing side.
5. Apply a bead of tube caulking around the three (3) housing sides of the roof vent where it meets the
hold-down angle.
6. Place hold-down angle (MIS-4404) on the assembled roof vent. The wide end of the hold-down angle
must face the vent discharge. Once aligned, screw nine (9) #10 self-drilling (S-280) screws through
the roof housing and into the hold-down angle.
