10. 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 31.
11. Cut out the Hole in the Roof
Measure to either side of the nail and mark the 17” x 17”
or 17” x 26” 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
roof framing details.
12. Assemble the Chimney Sections
Through the Roof
Continue to add chimney sections through the roof
opening, maintaining at least a 2” air space.
13. 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 (TR11), a round telescoping termination cap
(TR11T) or a square termination cap (ST1175). A chase
installation must use a chase top. Chase tops are
available from your Heatilator distributor. See the
section titled “Constructing a Chase” for building a
chase.
14. Install the Outside Air Kit
Outside air kits are supplied as a standard feature
with this fireplace and their use is highly
recommended to minimize the effects of negative
pressure within the structure. It is recommended to
utilize the shortest duct run to optimize the
performance of the outside air kits. The outside air kit
inlet thimble should be positioned at least four feet
above the ground level, in a manner that will not allow
snow, leaves, etc. to block the inlet.
Note:
tained from the top of the uppermost chimney sec-
tion to the outside combustion air inlets.
The outside air kits are installed on both sides of the
fireplace. See Figure 32 for handle location/operation.
15. Install the Chimney Air Kit
When installing the chimney air kit, follow the
instructions provided with this accessory.
