Hardware Installation
Attach the inner rails and front mounting bracket to the Firebox
Use these steps to attach the inner rails and front mounting brackets to the Firebox.
1. Locate the six shorter flat head screws (A), and the front ear brackets and screws.
2. Use three screws provided with the front ear brackets to attach a bracket to the front of the Firebox on
one side.
3. Put the inner rail against one side of the Firebox. Make sure that the safety lock tab faces out, and that
the notched end of the rail is located toward the rear of the Firebox.
4. Align the screw holes in the rail with the holes on the sides of the Firebox.
5. Attach the inner rail to the Firebox with three of the shorter flat head screws.
6. Repeat these steps to attach the other inner rail and front ear bracket to the other side.
Attach the L-shaped brackets to the outer rails
The four L-shaped brackets secure the outer rails to the rack. You must attach the L-shaped brackets to the
outer rails first.
1. Locate the eight flat head screws and the eight nuts (B).
2. Use two flat head screws and two nuts to connect an L-shaped bracket to the outer rail through any
two of the four holes at the end of the outer rail. Position each nut on the outside of the bracket, and
attach a screw from the inside of the outer rail through the bracket.
3. Do not fully tighten the nuts yet.
4. The outer rail includes a center rail that slides back and forth. Slide the center rail to expose the screw
holes at the other end of the rail.
