INSTALLATION
Installing the Outer Vent Heat Shields
(Partition Wall Installation)
1. Before you install the additional vent pipe and elbow(s)
that will complete the venting installation, you must first
install the second sections of the vent pipe heat shields
to protect the combustible materials around the vent
pipe pass-through in the partition wall that the fireplace
is mounted on. Each shield half simply slips over the
half you previously attached to the fireplace mounting
plate and that can now be seen inside the vent pass-
through in the partition wall.
2. Install the outer shield first and the inner second. Leave
at least 2" of both shields protruding past the partition
wall framing or wall covering. See the photo on page
32.
Vent Pipe and Vent Termination Installation
(Partition Wall Installation)
1. The specific details of the vent configuration from the
vent starter pipe on the fireplace to the horizontal
or vertical vent termination (cap) when the fireplace
is installed on an interior wall of the house will vary
depending on the location of the fireplace on the wall,
what is on the back side of the wall, where the vent
termination will be located (roof or exterior wall) and
on other code requirements for the location of the
vent termination as shown pages 24-25. However, the
maximum vent length, measured along the centerline
of the pipe, from the back of the fireplace to the
start of the vent termination cannot exceed 30 feet,
including a maximum of 20 feet of vertical rise and a
maximum of 10 feet of horizontal run. If more than two
90° elbows (or equivalent 45° elbows) are needed for
your installation, the maximum amount of horizontal run
allowed is reduced. See the venting section starting on
page 18 for specific information. It is important to plan
the installation in advance so that you can accurately
locate the any wall or ceiling pass-throughs and the
vent termination on the exterior wall or roof. The vent
pipe sections are available only in certain increments of
length and in adjustable length sections. Plan carefully
before you start!
2. You will find it helpful to leave access to the area
behind the partition wall to facilitate installation of the
vent components. The pipe sections may have twist
lock connections which will be difficult to execute
without good access.
3. Be sure that the two vent pipe heat shields extend
at least 2" beyond the rear side of the partition wall
adjacent to the fireplace after the venting is installed.
4. Maintain a minimum 1 1/2" unobstructed air space
around the vent pipe where it passes through other
interior walls, the ceiling, the exterior wall or the roof.
5.
Note:
Vent manufacturer’s instructions and some
building codes may require the addition of blocking
above and below all wall pass-throughs, the addition
of vent manufacturer supplied fire-stops, wall thimbles,
attic insulation shields, interior trim collars, vent support
brackets, or other components. Please check with the
authority having jurisdiction in your area when planning
the venting installation to determine the specific code
requirements and exact venting components that are
required for your installation.
