OWNER’S MANUAL
Flat Ceiling Installation
1.
Cut a 10" square hole in the ceiling us-
ing the locating hole as a center point.
The opening should be framed to
10"x10" (254mm x 254mm) inside di-
mensions, as shown in Figure 25 on
page 13 using framing lumber the same
size as the ceiling joists. If the area
above the ceiling is an insulated ceil-
ing or a room, nail firestop from the
top side. This prevents loose insulation
from falling into the required clearance
space. Otherwise, install firestop below
the framed hole. The firestop should be
installed with no less than three nails
per side (see Figure 33, page 16).
2.
Assemble the desired lengths of pipe
and elbows necessary to reach from the
burner system flue up through the
firestop. All connections must be
sealed with high temperature silicone
sealant as specified in the second warn-
ing statement on page 11. Be sure all
pipe and elbow connections are fully
twist-locked (see Figure 24, page 13).
1.
Determine the route your vertical vent-
ing will take. If ceiling joists, roof
rafters, or other framing will obstruct
the venting system, consider an offset
(see Figure 32) to avoid cutting
loadbearing members.
Note:
Pay spe-
cial attention to these installation in-
structions for required clearances (air
space) to combustibles when passing
through ceilings, walls, roofs, enclo-
sures, attic rafters, etc. Do not pack air
spaces with insulation. Also note maxi-
mum vertical rise of the venting sys-
tem and any maximum horizontal off-
set limitations. Offsets must fall within
the parameters shown in Figure 21 on
page 10.
2.
Set the stove in desired location. Drop
a plumb line down from the ceiling to
the position of the burner system exit
flue. 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 locating hole in the ceil-
ing. Mark the center point where the
vent will penetrate the roof. Drill a
small locating hole at this point.
