Vertical High Wind Termination
Installation
Note: Vertical restrictor must be installed in
all vertical installations.
1. Determine route your vertical venting
will take. If ceiling joists, roof rafters or
other framing will obstruct venting system,
consider an offset (see Figure 16) 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 venting system and any
maximum horizontal offset limitations.
2. Set fireplace in desired location. Drop a
plumb line down from ceiling to position
of fireplace exit flue. Mark center point
where vent will penetrate ceiling. Drill a
small locating hole at this point.
3. Drop a plumb line from inside of roof to
locating hole in ceiling. Mark center point
where vent will penetrate roof. Drill a small
locating hole at this point.

Flat Ceiling Installation
1. Cut a 11
locating hole as a center point. Opening
should be framed to 11
dimensions, as shown in Figure 9 on page
12 using framing lumber the same size as
ceiling joists. If area above ceiling is an
insulated ceiling or an attic, nail firestop
from top side. This prevents loose insula-
tion from falling into required clearance
space. If area above ceiling is a living
space, install firestop below framed hole.
Firestop should be installed with no less
than three nails per side (see Figure 17).
If area above is an attic or insulated area,
install firestop above framed hole.
If area above is a living space, install
firestop below framed hole.
