Assemble HOOD PANELS to HOOD RAIL ASSEMBLY.
The HOOD END ASSEMBLY with the MALE RIB is to
be installed first. (See Figure 7, DETAIL "E") Place the
remaining HOOD PANELS in place, interlocking panels
as you go. (See DETAIL "E") Secure each HOOD PANEL
to the HOOD RAIL ASSEMBLY as it is put in place,
using four (4) No. 12 X 3⁄8inch sheet metal screws with
sealing washers per HOOD PANEL. The HOOD END
ASSEMBLY with the FEMALE RIB is to be installed
last. NOTE: Hoods over 9 Ft. wide are supplied with
special HOOD CLIPS. (See DETAIL "F" in step 9)
HOOD PANELS have predrilled holes for HOOD CLIP
installation. Install CLIPS as HOOD PANELS are being
put in place, using one (1) No. 12 X 5⁄8inch sheet metal
screw with sealing washer per HOOD CLIP. To install
CLIPS in the last panel, leave the END BIRDSCREEN
ASSEMBLY out to provide access to the underside of
the hood. The END BIRDSCREEN ASSEMBLY can be
easily replaced after the hood is completely assembled.
