Step 3. Installing the Vent System
A. Vent System Approvals
These models are approved to use DVP-series direct
vent pipe components and terminations. Approved vent
system components are labeled for identification. This
pipe is tested and listed as an approved component of
the fireplace. The pipe is tested to be run inside an
enclosed wall. There is no requirement for inspection
openings at each joint within the wall. There is no re-
quired pitch for horizontal vent runs. NO OTHER VENT-
ING SYSTEMS OR COMPONENTS MAY BE USED.
Detailed installation instructions are included with
each vent termination kit and should be used in
conjunction with this Installers Guide. The draw-
ing below shows vent system components and ter-
minations.
The flame and ember appearance may vary based
on the type of fuel burned and the venting configura-
tion used.
Identifying Vent Components
The vent systems installed on this gas fireplace may
include one, two, or three 90°
elbow assemblies. The
relationships of vertical rise to horizontal run in vent
configurations using 90° elbows MUST BE strictly
adhered to. The rise to run relationships are shown
in the venting drawings and tables. Refer to the dia-
grams on the next several pages.
NOTE: Two 45° elbows may be used in place of one
90° elbow. rise to run ratios in the vent system must be
followed if 45° elbows are used.
NOTE: PIPES OVERLAP 1-1/4
INCHES (31.8mm) AT EACH JOINT.
