Step 3. Installing the Vent System
A. Vent System Approvals
This model has vent starting collars on the back of the unit.
This model uses SL D-series direct vent and SL-Flex vent
components (see Figures 4 and 5). Approved vent system
components are labeled for identification. This pipe is test-
ed 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 required pitch for horizontal vent runs.
NO OTHER VENTING SYSTEMS OR COMPONENTS MAY
BE USED.
WARNING: YOU MUST NOT MIX D-SERIES AND
!
SL D-SERIES COMPONENTS IN ANY VENT SYS-
TEM CONFIGURATION.

Vent Components and Terminations
Detailed installation instructions are included with each vent
termination kit and should be used in conjunction with this
Installers Guide.
The flame and ember appearance may vary based on the type
of fuel burned and the venting configuration used.
Identifying Vent Components
The vent systems installed on this gas fireplace may in-
clude one, two, or three 90° elbow assemblies. The rela-
tionships of vertical rise to horizontal run in vent configura-
tions 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. You MUST always maintain the MAXIMUM
and MINIMUM rise-to-run ratios in the vent system when
using 45° elbows.
