It might be necessary to flex the panel slightly to insert it into the second channel. Make certain the panel is perpendicular to the wall, and then nail. Depending on the installa- tion method being used, nails will be hammered either into a nailing strip or fascia board. Do not nail soffit panels tightly. Continue the installation by locking and nailing the panels. Make certain the panels are fully locked along their entire length. 38. soffit installation over open eaves installation Over Enclosed eaves Fascia cap or coil stock Nailing strip The procedure used to install soffit over enclosed eaves is almost identical Enclosed eave to that used for open eaves . The major difference is the installation of the J-Channel at the wall line rather than F-Channel (Figs.)

NOTE: Nails or fasteners installed through the bottom of the aluminum fascia panel may penetrate the ends of the Vinyl soffit panels in some installations. The following procedures are recommended if this situation occurs.

10 * Line up the aluminum fascia fasteners with the V-grooves in the Vinyl soffit panels to avoid cupping the soffit panel faces. * If Vinyl soffit panels are over 24 in length, enlarge the fastener hole in the Vinyl soffit Bend 1" panel 1/4 larger than the fascia fastener diameter. This will allow the soffit panels to expand normally and avoid potential buckling.
