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 identifi ca-
tion. This pipe is tested and listed as an approved
component of the fi replace. The pipe is tested to
be run inside an enclosed wall. There is no require-
ment for inspection openings at each joint within
the wall. There is no required pitch for horizontal
vent runs. NO OTHER VENTING 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
terminations.
The fl ame and ember appearance may vary based
on the type of fuel burned and the venting confi gu-
ration used.
Identifying Vent Components
The vent systems installed on this gas fi replace may
include one, two, or three 90°
elbow assemblies.
The relationships of vertical rise to horizontal run
in vent confi gurations using 90° elbows MUST BE
strictly adhered to. The rise to run relationships are
shown in the venting drawings and tables. Refer to
the diagrams 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 (31.8 mm) AT EACH JOINT.
