9. Mark the Exit Point of the Roof
Locate the point where the chimney will exit the roof
by plumbing down to the center of the chimney. Drive
a nail up through the roof to mark the center. See
Figure 12.
10. Cut Out the Hole in the Roof
Measure to either side of the nail and mark the
14-1/2 in. x 14-1/2 in. opening required. This is
measured on the horizontal; actual length may be
larger depending on the pitch of the roof. Cut out and
frame the opening. See
Chapter 25 of the Uniform
Building Code
for roof framing details.
Be sure to maintain a 2 in. minimum air space
between the chimney section and the roof.
11. Assemble the Chimney Sections
Through the Roof
Continue to add chimney sections through the roof
opening, maintaining at least a 2 in. air space.
12. Install the Roof Flashing
If a roof flashing is to be used, install the roof flashing
appropriate to the roof pitch and install a round
termination cap following the instructions shipped with
the cap.
For chase installations you can use a round
termination cap (TR344), a round telescoping
termination cap (TR342) or a square termination cap
(ST375, TS345, TS345P). A chase installation must
use a chase top. Chase tops are available from your
Heat-N-Glo distributor. Refer to page 23 for
information on building a chase.
13. Install the Chimney Air Kit (Required in
Canada)
When installing the chimney air kit, follow the
instructions provided with this accessory.
CAUTION:
The air kit handle may get hot while burning
the fireplace. Use care when operating the
handle.
