Installing the
Vent System
A. Vent System Approvals
These models are approved to use D-series direct
vent pipe components and terminations. Approved
vent system components are labeled for identification.
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 drawing below shows vent system
components and terminations.
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
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
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.
This model has vent starting collars on both the top and
the back of the unit. Depending upon the installation,
decide which ONE set of starting collars will be used to
attach the vent system. The starting collar sealing cap
must remain on the starting collar NOT used.
