Auto-Vent Installation
Assembly and Installation Instructions
The following instructions are for assembling and installing the auto-vent. First, check the packing list to
ensure all components have been shipped. The unit is easiest assembled in the upside down position
as shown in
Figure 1. Roof vent location should be as shown in Figure 5.
Assembly
1. Take all parts out of the shipping box and check if all parts are present.
2. Turn one (1) roof vent housing (MIS-6778) upside down. (See Figure 1.)
3. Insert 5/16" x 1-1/4" bin bolt with neoprene washer through hole in the side of roof vent housing. Place
jamb nut onto the bolt and tighten. (See Figure 1.)
4. Slide flap assembly (MIS-6777) onto bolt. The bolt should slide through hole in the flap assembly
bracket. Install with curvature cupped upward and the brackets in the position as shown.
5. 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 flap assembly bracket. Tighten nut against vent housing side.
6. Apply a bead of tube caulking around three (3) housing sides of the roof vent where it meets the
hold down angle.
7. Place hold down angle (MIS-4404) on the assembled roof vent. The wide end of the hold down angle
must face vent discharge. Once aligned, screw nine (9) #10 self-drilling (S-280) screws through the
roof housing and into the hold down angle.
