Roof Panel
Identical pre-punched roof panels are available from GSI for inlet and outlet sections of pneumatic fill
systems. Extruded lip of the panels provide for weather-tight installation. Caulking placed between angle
rings virtually eliminates all leakage problems. Rubber seal must be utilized at roof cap area to prevent
material “blow by” from pressurized systems.
To install fill kits in roof panels not pre-punched, cut 5-5/8" (143 mm) diameter holes in opposing roof
panels as shown
in Figure 13B and Figure 13C on Page 69 . Caulk sufficiently to provide weather-tight seal.
Refer to “peak ring seal strip” installation procedure when installing pneumatic fill kits.
Abnormal pressure may require us of optional “Cap Hold-Down Package”. (BLK-10474)
