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
23 to avoid cutting load bearing members.

For optimal fl ame appearance, a restrictor disk is necessary
on straight vertical runs of 10' of more.
•
Runs may not incorporate elbows.
•
The disk is part number 56D3027 and is included in
installation manual packet.
•
Drop the disk into a 5" inner collar before installing
the fi rst section of fl ue or install at the last section
before installing the termination.
•
An additional disk may be installed on runs of 35' or more.
Rotate disks 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 22 and 23.
2. Set fi replace in desired location. Drop a line plumb down
from the ceiling to the position of the fl ue exit. Mark the
center point where the vent will penetrate the ceiling.
Drill a small locating hole a this point.
Drop a plumb line from the inside of the roof to the ceiling
locating hole in the ceiling. Mark the center point where
the vent will penetrate the roof. Drill a small locating hole
at this point.

sions as shown in Figure 25 using framing lumber the
same size as the ceiling joist. If the area above the
ceiling is an insulated ceiling or a room, nail fi restop from
the top side. This prevents loose insulation from falling
into the required clearance space. Figure 24. Otherwise,
install fi restop below the framed hole. Figure 25
