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 venting system,
consider an offset (see Figure 13) 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
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.
Drop a plumb line from inside roof to
locating hole in ceiling. Mark center point
where vent will penetrate roof. Drill a small
locating hole at this point.
