Hopper Assembly
1. Mount the upper hopper panel upside down on a flat,
clean surface. Use the tube sheet as a fixture if there is
no flat area to work on. Do not apply sealant between the
hopper panel and the tube sheet.
2. Temporary supports at the ends of each hopper panel
may be required until the upper hopper ring is complete.

3. Before connecting the adjacent hopper panel, apply
sealant to the mating flange within 1/8-in of both flange
edges as shown.
4. Set the next panel and hand-tighten the hardware
(connecting bolts should draw the adjoining flanges
together but still allow for some slippage). Repeat steps
until upper hopper assembly is complete.
