Section 10 - Setting Typical Intermediate Units
Thread the WC19 gasket in
the adjacent head. Then
apply sealant to the end to
create a butt seal between
the two WC19 gaskets.
HC07 must be guided
into the cavity before
lowering unit down
onto the shim packs.
18. Before lowering the unit down any farther, insert the remaining HC07 foam backer from the unit that is already set into the cavity by using a putty knife or
similar tool. Note: This is a very critical step that is easily forgotten and could cause units to leak if missed. See Figure 107.
19. Lower the unit down into position to completely engage the unit splice bars (FM13, FM14 at 7” system) (FM15, FM16 at 8” system) at the stack joint. The
hook anchors should also be hooked onto the slab anchor. The unit should now be setting hard on the shims. See Figure 90.
20. Approximately 2” to 3” of WC19 gasket at the gutter engagement leg must be slid into the adjacent gutter gasket reglet. See Figure 108.
21. Adjust the jack bolt as required for the unit to set hard on the shim pack at the starter sill below. See Figures 107 and 109.

lower the unit.
