VENT INSTALLATION
INSTALLATION FOR VERTICAL TERMINATION
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. See Figure 30 to avoid cutting load bearing
members.
For optimal flame appearance, a restrictor disk is necessary on
straight vertical runs of 20' of more.
• Runs may not incorporate elbows.
• The disk is part number 45D0551 and is included in instal-
lation manual packet.
• Drop the disk into a 4" inner collar before installing the first
section of flue 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 shows in Figure 13, page 20.
2. Set fireplace in desired location. Drop a line plumb down from
the ceiling to the position of the flue 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.
FLAT CEILING INSTALLATION
1. Cut a 9
1
/2" (241mm) square hole in the ceiling using the locating
hole as a center point The opening should be framed to 9
1
/2"x9
1
/2"
(241mm x 241mm) inside dimensions as shown in Figure 32using
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. See Figure 31. Otherwise, install
firestop below the framed hole. See Figure 32.
2. Assemble the desired lengths of pipe and elbows necessary to
reach from the burner system flue up through the firestop. Be sure
pipe and elbow connections are fully twist-locked. See Figure
15, page 18.
