INSTALLATION FOR VERTICAL
TERMINATION
Note:
Vertical restrictor must be installed in all
vertical installations.
1. Determine the route your vertical venting
will take. If ceiling joists, roof rafters or
other framing will obstruct the venting
system, consider an offset (see Figure 19)
to avoid cutting load bearing members.
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 verti-
cal rise of the venting system and any
maximum horizontal offset limitations.
2. Set the fireplace in desired location. Drop
a plumb line down from the ceiling to the
position of the fireplace 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 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 11
1
/
2
" square hole in the ceiling us-
ing the locating hole as a center point. The
opening should be framed to 11
1
/
2
" x 11
1
/
2
" inside dimensions, as shown in Figure
9 on page 10 using framing lumber the
same size as the ceiling joists. If the area
above the ceiling is an insulated ceiling
or an 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 three nails per side (see Figure 20).
2. Assemble the desired lengths of pipe
and elbows necessary to reach from the
fireplace flue up through the firestop. Be
sure all pipe and elbow connections are
fully twist-locked (see Figure 8, page 10).
3. Cut a hole in the roof using the locating
hole as a center point. (Cover any ex
-
posed open vent pipes before cutting hole
in roof.) The 11
1
/
2
" x 11
1
/
2
" 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 materi-
als. Frame the opening as shown in Figure
9, page 11.
4. Connect a section of pipe and extend up
through the hole.
Note:
If an offset is needed to avoid ob-
structions, you must support the vent pipe
every 3 feet. Use wall straps for this pur-
pose (see Figure 19). Whenever possible,
use 45° elbows instead of 90° elbows. The
45° elbow offers less restriction to the flow
of the flue gases and intake air.
5. Place the flashing over the pipe section(s)
extending through the roof. Secure the
base of the flashing to the roof and fram
-
ing with roofing nails. Be sure roofing
material overlaps the top edge of the
flashing as shown in Figure 19. There
must be a 1" clearance from the vent pipe
to combustible materials.
Figure 20 - Installing Firestop
If area above is living
space, install firestop
below framed hole.
If area above is an
attic or insulated
area, install firestop
above framed hole.
