CATHEDRAL CEILING
INSTALLATION
Step 1.
Follow installation Steps 1 and 2 under
Vertical Terminations.
Step 2.
Using the plumb bob, mark Figure 18
the center line of the venting system on the ceil -
ing and drill a small hole through the ceiling and
roof at this point. From the roof, locate the drill
hole and mark the outline of the Cathedral Ceil -
ing Support Box.
Step 3.
Remove shingles or other roof cover -
ing as necessary to cut the rectangular hole
for the Support Box (refer to Table 1 for dimen -
sions). Cut the hole 1/8-inch larger than the
Support Box outline.
Step 4.
Lower the Support Box through the
hole in the roof until Support Box protrudes at
least 1-inch below the low side of the ceiling
(Fig. 20). Align the Support Box both vertically
and horizontally with a level. Temporarily tack
the Support Box in place through the inside
walls and into the roof sheathing.
Step 5.
Using tin snips, cut the Support Box
from the top corners down to the roof line, and
fold the resulting flaps over the roof sheathing.
The flaps may be trimmed as needed (Fig. 21).
Before nailing it to the roof, run a bead of non-
hardening sealant around the Support Box, to
make a seal between the Support Box and the
roof. Clean out any combustible material from
inside the Support Box.
Step 6.
Follow Steps 4 and 5 (page 14) of the
Vertical Installation Instructions.
Step 7.
Follow Steps 7 through 10 (page 15 &
16) of the Vertical Installation Instructions.
Step 8.
Install the black Trim Collar around the
outside of the Cathedral Ceiling Support Box.
The two pieces of the Trim Collar slide over one
another to allow for easy adjustment around the
Support Box. Using the six (6) screws provided,
secure the four corners and the overlapping
sections of the Trim Collar to the underside of
ceiling. You may want to pre-drill the holes for
the overlapped sections for ease of installation
(Fig. 22).
