PREPARE THE RECESS
A flat recess and accurately installed frames are critical to the overall performance of the
grille.
1.
The rough opening for the frame should be at least 3
” deep
and at least the width and
length of the frame. This allows room to maneuver the frame and provides clearance
for the anchor bolts.
2.
Verify that the bottom of the recess is flat within 1/8
”over 10’. The recess must be flat
to prevent damage to the grille.
Utilize a self-leveling compound (provided by others) if
necessary to ensure a level floor surface.
ASSEMBLE THE FRAMES
Frames that exceed 96
”
in either width or traffic direction are shipped in separate pieces.
1.
Assemble the frame sections according to the shop drawings. Splice plates and pins
are provided for connecting frame pieces together.
See Figure 1

2.
Make sure that the frame is plumb, that corner conditions are joined at the correct
angles, and that it is at the correct height. Also, check the measurements of the frame
against the shop drawings in several locations to make sure that the sizes are correct.
The grille will not fit if the frame is not installed as indicated on the shop drawings.
