7.0 VENTING

7.1 Approved Vent Systems

This appliance is equipped for use with a 5" (127mm) exhaust by
8" (203mm) air intake co-axial vent pipe system. This appliance is
approved for use with Kozy Heat 5" (127mm) x 8" (177mm) #800
Series Flexible Direct Vent System (horizontal terminations only).
Refer to Section 7.6 #800-2 Series Direct Vent Termination Kit(s) on
page 27 for venting components and installation instructions.
Other approved vent manufacturers (horizontal and vertical
terminations): American Metal Products (Ameri-Vent), BDM, ICC, Metal
Fab, Olympia Chimney Supply, Inc., Security, Selkirk, and Simpson
DuraVent. Refer to the vent manufacturer's installation manual for
complete installation instructions. Vent installation must conform
with venting requirements and restrictions as outlined in this manual.
Vent reduction from a 5" exhaust to a 4" exhaust may be used
for vertical vent runs using a listed reducer from the approved
vent manufacturer as listed above. Refer to vent manufacturer's
instructions.
This appliance can be adapted to use 3" x 3" flexible co-linear vent
pipes when used in combination with an existing minimum 6"
x 8" ID masonry or 7" ID class A metal chimney. Refer to the vent
manufacturer's instructions.

7.2 Venting Requirements

NOTE: Consult the local and national installation codes to assure
adequate combustion and ventilation air is available. Venting
requirements apply to both natural gas and propane.
• Flame height and appearance will vary depending upon venting
configuration and the type of fuel used.
• Provide a means for visually checking the vent connection to the
appliance after the fireplace is installed.
• A minimum of 1 in (25 mm) clearance on all sides of the
vertical vent pipe must be maintained. Attic insulation shields
may be insulated using unfaced insulation products listed as
noncombustible per ASTM E 136.
• Kozy Heat's #800-WPT series, or wall thimble products that
comply with a minimum of 3 in (76 mm) clearance on the top
side and a minimum of 1 in (25 mm) clearance on the bottom,
left, and right sides of the horizontal vent pipe at the wall
pass-through must be maintained. Wall thimble products that
comply with the required clearances to combustibles must be
installed for all horizontal vent runs that pass through interior
or exterior walls. These wall thimble products may be insulated
using unfaced insulation products listed as noncombustible
per ASTM E 136. If using a 4" x 6-5/8" reducer, follow vent pipe
manufacturer's wall thimble installation instructions.

7.3 Use of Elbows

• MAXIMUM NUMBER OF ELBOWS: 5
• For each additional 90° elbow used after the first elbow, 3 ft (91.4
cm) must be subtracted from maximum venting allowed.
• For each 45° elbow used, 1½ ft (457 mm) must be subtracted
from maximum venting allowed.
• (2) 45° degree elbows may be used in place of (1) 90° elbow.

7.4 Vent Restriction

Burner flame appearance and characteristics are affected by altitude,
fuel quality, venting configuration, and other factors. To achieve
desirable flame appearance, the vent exhaust may be restricted by
the restrictor plate (included in components packet).
The restrictor plate is shipped with all inner rings intact, and when
installed, provides the most vent restriction. There are (2) inner rings
that can be knocked out. The inner most ring knocked out will create
less restriction, and the outer most ring knocked out will create the
least amount of restriction.
Follow Figure 8.1 for restrictor plate installation before attaching
venting.
see Section 11.2.2 Vent Restriction (after installation) on page 42.
