Note: Pay special attention to these instal-
lation 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 maxi-
mum horizontal offset limitations. Offsets
must fall within the parameters shown in
Figures 24 through 26, pages 15 and 16.
2. Set stove in desired location. Drop a plumb
line down from the ceiling to the position of
burner system exit flue. Mark center point
where vent will penetrate 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 ceiling. Mark
center point where vent will penetrate roof.
Drill a small locating hole at this point.
Flat Ceiling Installation
1. Cut a 10" (25.4 cm) square hole in the
ceiling using the locating hole as a cen-
ter point. The opening should be framed
to 10"x10" (25.4 cm x 25.4 cm) inside
dimensions, as shown in Figure 13 on
page 11 using framing lumber the same
size as the ceiling joists. If the area above
the ceiling is an insulated ceiling or and
attic, nail firestop from the top side. This
prevents loose insulation from falling
into the required clearance space. If the
area above the ceiling is a living space,

install firestop below the framed hole. The
firestop should be installed with no less
than 3 nails per side (see Figure 21).
2. Assemble desired lengths of pipe and
elbows necessary to reach from the
burner system flue up through the
firestop. Be sure all pipe and elbow
connections are fully twist-locked (see
Figure 12, page 11).
3. Cut a hole in the roof using the locat-
ing hole as a center point. (Cover any
exposed open vent pipes before cutting
hole in roof.) The 10"x10" (25.4 cm x
25.4 cm) hole must be measured on the
horizontal; actual length may be larger
depending on the pitch of the roof. There
must be a 1" clearance from the vent pipe
to combustible materials. Frame opening
as shown in Figure 13 on page 11.
4. Connect a section of pipe and extend
up through the hole.
Note: If an offset is
needed to avoid obstructions, you must
support vent pipe every 3 feet. Use wall
straps for this purpose (see Figure 20,
page 13). Whenever possible, use 45°
elbows instead of 90° elbows. The 45°
elbow offers less restriction to the flow of
flue gases and intake air.
5. Place flashing over pipe section(s) ex
-
tending through the roof. Secure base of
flashing to roof and framing with roofing
nails. Be sure roofing material overlaps
the top edge of the flashing as shown in
Figure 20, page 13. There must be a 1"
clearance from vent pipe to combustible
materials.
6. Continue to add pipe sections until the
height of the vent cap meets the minimum
building code requirements described in
Figure 9 on page 8.
Note: You must in-
crease vent height for steep roof pitches.
Nearby trees, adjoining rooflines, steep
pitched roofs, and other similar factors
may cause poor draft or down-drafting
in high winds. Increasing the vent height
may solve this problem.
7. Twist-lock vent cap onto the last section
of vent pipe.

If area above is a living space, install
firestop below framed hole.
If area above is an attic, install firestop
above framed hole.
