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 35
to avoid cut-
ting 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 shows in Figure 18, Page 20.
2. Set fireplace in desired location. Drop a plumb line 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 at 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
/
" (241 mm) square hole in the ceiling using the
locating hole as a center point The opening should be
framed to 9
1
/
" x 9
1
/
" (241 mm x 241 mm) inside dimen-
sions as shown in
Figure 37
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 36.
Otherwise, install firestop below
the framed hole.
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.
Page 21, Figure 21
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 9
1
/
" x 9
1/
" (241 mm x 241 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 21, Figure
20
.
