VERTICAL FURRING. The vertical furring
(fig. 9- 12) should be installed immediately after the
base, corner, and gable furrings are in place. The
center line of the furring on each side of the window
should be in line with the center line of the end-wall
panel corrugations (shown in the inserts). After the
end-wall hardboard has been installed, attach side and
top flashing to the door. Attach flashing to the furring
with 4d aluminum nails and to the door frames with
1/2-inch No. 10 sheet-metal screws, as shown in figure
SIDEWALL AND CEILING FURRING.
After installing the end-wall liner, install furring for
the sidewall and ceiling. Cut the base so the end just
clears the inside flange of the center-frame column.
Nail the furring in the same manner as the end walls.
HARDBOARD FLASHING. With the furring
in place, you can now install the hardboard liner. Install
the top and bottom hardboard flashing, as shown in
figure 9-14. Insert the outside edge into the retaining
grooves in the window. Nail metal flashing angle and
hardboard to the horizontal furring with 4d aluminum
nails 1 foot 8 inches OC. Install side hard- board flash-
ing and metal flashing angles using the same procedures
The installed ceiling furring should intersect side-
wall furring. When all the ceiling furring has been
installed, the hardboard liner can be installed. Remem-
ber the 1/8-inch gap between panels. The smoke stack
assembly should be attached to the block- ing and
furring with 4d aluminum nails. Hand trim the hard-
board flashing for the ends of the ventilator opening and
attach the metal ventilator flashing (see fig. 9- 15).
TRIM. Install the cave molding with the
beveled edge against the ceiling panels. Attach each
sidewall furring strip with 4d aluminum nails. Use
Figure 9-12.-Placing furring for liners.
