Installing the Roof Vents
The following instructions are for installing the wire grill guard roof vent and the auto roof vent.
Before You Begin
The wire grill guard roof vent and the auto roof vent must be assembled prior to installing.
1. If the roof panel (D) does not have a pre-punched hole for the roof vent assembly (A), a hole must be
cut. The cut hole should match the roof vent assembly (A). The hole’s inside edge should be approxi-
mately 15 ft. (F) from the roof panel eave.
2. Place the three foam strips (C) on the roof panel (D), as shown, and position the roof vent assembly
(A) over the foam strips (C). Install bolts (B) and nuts (H), securing the roof vent assembly (A) to the
roof panel (D).
3. Instal bolts (G) and nuts (E) from the underside of the roof panel (D) securing the front of the hold-
down angle to the roof panel as shown. Tighten the hardware to the recommended torque specifica-
tions. See
Bolt Torque Specifications, page 26 .
