Figure 13A Typical Installation
Step 1: Using reinforcing plate as a template, mark hole in hopper for cutting.
Step 2: Using a torch or saw, cut the hole in hopper sheets for tube.
Step 3: Remove enough bolts from hopper seam to allow reinforcing plate to set down on
hopper panels.
Step 4: Install reinforcing plate on inside of hopper (and outside for 27' and 30' tanks). Full weld and
field drill holes and bolt in place. Drill holes through reinforcing plate where it overlaps holes
in seam and reinstall bolts.
Step 5: Install torpedo head at open end of tube and screw in place as shown (screws not included).
Step 6: Four (4) angles with corrugated pieces welded on them are supplied for each tube (two (2)
per side). Bolt or weld each angle to the hopper sheet and screw or weld the corrugated
material to the perforated tube (#14 x 1" self-drilling tek screws not provided).
Step 7: Full weld inside and outside around perimeter of aeration tube saddle ‘tee’.
Step 8: Bolt or weld on angle ring for attachment of fan.
Step 9: Touch up any welded areas with a rust inhibitive type paint.
