1. Determine the route your vertical venting will take. If
ceiling joist, roof rafters or other framing will obstruct
the venting system, consider an offset. Refer to Figure
24 to avoid cutting load bearing members.

For optimal flame appearance, a restrictor disc is necessary
on straight vertical runs of 10' of more.
•
Runs may not incorporate elbows.
•
The disc is part number 56D3027 and is included in
installation manual packet.
•
Drop the disc into a 5" inner collar before installing
the first section of flue or install at the last section
before installing the termination. Or disc may be
installed from inside firebox into the 5" inner collar.
•
An additional disc may be installed on runs of 35' or more.
Rotate discs perpendicular to each other.
nOte: Pay special attention to these installation instructions
for required clearances (air space) to combustibles when
passing through ceilings, walls, roofs, enclosures, attic
rafters, etc. Do not pack air spaces with insulation. Also
note maximum vertical rise of the venting system and any
maximum horizontal offset limitations. Offsets must fall
within the parameters shown in Figures 23 and 24.
2. Set fireplace in desired location. Drop a line plumb down
1
from the ceiling to the position of the flue exit. Mark the
center point where the vent will penetrate the ceiling.
2
Drill a small locating hole a this point.
Drop a plumb line from the inside of the roof to the ceiling

1. Cut a 10Z\x" (241 mm) square hole in the ceiling using the
locating hole as a center point The opening should be
framed to 10Z\x"x10Z\x" (241 x 241 mm) inside dimensions
as shown in Figure 26 using framing lumber the same
size as the ceiling joist. If the area above the ceiling is
an insulated ceiling or a room, nail firestop from the top
side. This prevents loose insulation from falling into the
required clearance space. Figure 25. Otherwise, install
firestop below the framed hole. Figure 26
