. Determine if ceiling joists,
roof rafters, framing or other materials
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 Round Ceiling
Support/Wall Thimble Cover in a at
ceiling, refer to Table 1, page 8 and
cut a square hole in the ceiling (unless
otherwise specied by the appliance
manufacturer) centered on the hole
drilled in Step 2. Frame the hole as
shown (Fig. 14).
Step 4. If the twist-lock Appliance
Adaptor has not been installed on the
stove by the manufacturer, install it
now in accordance with the appliance
instruction manual.
Step 5. Assemble the desired Pipe
Sections and Elbows necessary to
reach from the Appliance Adaptor up
through the Round Ceiling Cover or
Support Box. Ensure that all Pipe and
Elbow connections are in their fully
twist-locked position.
Step 6. Cut a hole in the roof
centered on the small drill hole placed
in the roof in Step 2. The opening
should be of sufcient size to meet the
minimum requirements for clearance
to combustibles, as specied by the
appliance manufacturer. Continue to
assemble Pipe Sections and Elbows
as necessary to reach up through the
rooine. Galvanized Pipe and Elbows
may be utilized in the attic, as well as
above the rooine. The galvanized
nish is desirable above the rooine,
due to higher corrosion resistance.

 If exact lengths or distances must
be met between Elbow offsets or
elsewhere, use the Pipe Extensions
to adjust onto standard Pipe Sections
(Fig. 15).
 If an offset is necessary in the attic
to avoid obstructions, it is important to
support the vent pipe in order to avoid
excessive stress on the Elbows. Wall
Straps or plumbers tape may be used
for this purpose (Fig. 16).
