ASSEMBLY & INSTALLATION
Installing the Outer Vent Heat Shields (Partition Wall
Installation)
1. Before you install the additional vent pipe and el-
bow(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 pre-
viously 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 illustration on page 24.
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 loca-
tion of the vent termination as shown page 15. 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 8 for specific in-
formation. It is important to plan the installation in advance so that you can accurately locate the any
wall or ceiling pass-through’s and the vent termination on the exterior wall or roof. The vent pipe sec-
tions 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 exe-
cute 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-through’s, 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.
