and ICC EXCELDirect venting components. Although you may use the pipe components (straight pipe, elbows,
etc.) from any of the listed manufacturers, you may only use the vent terminations (caps) listed in the chart on
page 9. For installations where a snorkel is needed, please note that only three snorkels are approved for use.
Please plan your installation accordingly.
For all specific venting installation requirements, follow the installation instructions included by the venting
manufacturer with the venting system components you have chosen.
Please note:
•
For venting configurations that include no vertical rise, a total horizontal vent run of up to 30 inches
(and including one 45° elbow) is allowed. However, if your installation has room to add a vertical pipe
section, we suggest adding at least one foot of vertical rise to the system.
•
For venting configurations that include vertical rise, it is assumed that the installation will include at least
one 90° elbow. Up to three additional 90° elbows (or equivalent 45° elbows) may also be used. The
total venting may not exceed 20 feet of vertical rise and/or 10 feet horizontal run. Refer to the venting
charts starting on pages 10 & 11 for specific details while you plan your installation. Note: The number
of elbows impacts the maximum allowable horizontal vent run.

•
Many installations will involve venting directly through standard 2 X 4 or 2 X 6 construction exterior wall
to a horizontal vent termination (cap). The vent starter pipe has been designed to accommodate those
two common installations without the use of any additional venting components other than a standard
horizontal cap. See the chart on page 9 for a list of approved vent caps.
•
If the fireplace will be installed on an interior wall or other location that precludes venting directly through
an outside wall to a horizontal vent cap, or if the distance to the outside wall exceeds 30", one or more
elbows will be required to allow addition of the required vertical venting to the installation. When vertical
venting is required, the fireplace venting may be terminated with either a vertical or horizontal vent cap
depending on the specifics of the installation. Refer to the venting charts starting on pages 10 & 11 for
specific venting requirements and see the chart on page 9 for a list of approved vent caps before you
plan your installation.
•
There should be a 1 1/2" overlap of the vent and combustion air tubes, when telescopic joints are used.
•
A minimum clear space of 1 1/2" must be maintained around the vent pipe where it penetrates the first
combustible wall adjacent to the fireplace (either the outside wall for the direct-through-the-wall
installation or the partition wall for the 45° or other interior wall installations). The special vent pipe heat
shields that are provided with the Eclipse must also be installed in the first wall adjacent to the fireplace.
A minimum clear space of 1 1/2" must also be maintained where the vent pipe penetrates any other
interior wall, exterior wall, ceiling or roof.
•
The ECLIPSE may also be installed in front of an existing fireplace opening utilizing special co-linear
venting components available from the venting manufacturers. These systems split and then recombine
the co-axial air and exhaust and allow the use of flexible venting. This makes it easier to run the venting
through the narrow fireplace damper opening to the top of the chimney. Refer to the vent
manufacturers' instructions. Use the vertical venting column (0 feet Horizontal Run) in the venting
charts to determine the required restrictor settings depending on the height of chimney.
Using Vent Charts
The location of the vent termination must meet the requirements of the current edition of ANSI Z223.1/NFPA
