STEP 9
Install the perforated plenum roof sheets over the
rafters by pushing the corresponding rib holes over
the inverted long bolts in the rafter (fig. h). After
the adjacent roof sheet is placed and the rib lap is
made, install a 5/16” flange nut over the protruding
bolt shanks and finger tighten. Now locate and
install the grain band support posts (fig. g and h) If
your Ezee Dry is a 30’ batch unit, ten of the inner
roof sheets will have upper dump hoppers in addition
to the lower dump hoppers. Space these sheets
uniformly around the bin. Continue around the bin
installing the perforated plenum roof sheets in a
like manner until all are in place. Next, Install 5/16
x 2 3/4” bolts in all remaining plenum sheet rafter
holes. Install the lower, and, if applicable, upper
plenum rafter supports in the holes at the lower
rafter flange using 5/16” x 1” bin bolts. At this time,
all remaining untightened bolts in the plenum sheet
and rafters including the 1/2” rafter bolts may be
tightened. Since the grain band assemblies are best
left off to provide working space until the outer
roof is installed, place all bands distributed around
the plenum roof near the bin sidewall for ready
availability later. (see pages 30-31)
STEP 10
Install the top half ring on the first full width
ring using 5/16” x 1” bin bolts in the vertical
seams and 5/16” x 1 1/4” bin bolts in the
horizontal seam and fully tighten all bolts
(fig. i). The top horizontal seem hole should
be spaced at 3 1/8” to facilitate roof
construction. The sidewall flashing will be
placed over the 1 1/4” bolt shanks.
