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, con-
sider an offset. Refer to Figure 31 to avoid cutting load bearing
members.
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 on Page 22, Figure 21.
. 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 locat-
ing 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 9Z\x" (41 mm) square hole in the ceiling using the locating
hole as a center point The opening should be framed to 9Z\x" x 9Z\x"
(41 x 41 mm) inside dimensions as shown in Figure 32 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 32. Otherwise, install firestop below the
framed hole.
. 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. Page
20, Figure 17
3. Cut a hole in the roof using the locating hole as a center point.
(Cover any exposed open vent pipes before cutting hole in
roof). The 9Z\x" x 9Z\x" (41 x 41 mm) hole must be measured
on the horizontal. Actual length may be larger depending on
the pitch of the roof. There must be a 1" minimum clearance
from the vent pipe to combustible materials. (Insulation should
be considered a combustible material) Frame the opening as
shown on Page 20, Figure 16.
