Step 1. M a i n t a i n
c l e a r a n c e s
between venting
and combustible
building materials
as stated earlier
in this section. Do
not pack air spaces
with insulation.
Check with the
Allowable Vent
C o n f i g u r a t i o n s
page when
planning your
installation to
ensure the vertical
and horizontal
elements of your
installation are
within these limits.
Step 2. Set the replace in its desired location. Drop a plum bob down
from the ceiling to the position of the appliance ue exit, and
mark the location where the vent will penetrate the ceiling. Drill a
small hole at this point. Next, drop a plumb bob from the roof to
the hole previously drilled in the ceiling, and mark the spot where
the vent will penetrate the roof. Determine if ceiling joists, roof
rafters, or other framing will obstruct the venting system. You
may wish to relocate the appliance, or to offset, to avoid cutting
load bearing members.
Step 3. To install the Ceiling Firestop in a at ceiling, cut a square hole in the ceiling 11”x11” (280x280mm)
square for 8” x 5” pipe, centered on the hole drilled in Step 2. Frame the hole as shown in Figure 35.
Step 4. Assemble the desired lengths
of galvanized Pipe and Elbows
necessary to reach from the
Appliance Adaptor up through the
Ceiling Firestop. Ensure that all Pipe
and Elbow connections are in their
fully twist-locked position.
Step 5. Cut a hole in the roof centered on
the small drill hole placed in the
roof in Step 2. The hole should
be of sufcient size to meet the
minimum requirements for clearance
to combustibles, as specied earlier.
Continue to assemble lengths of Pipe
and Elbows necessary to reach from
the Ceiling Firestop up through the
roof line.
