Figure 8. Vent System Components and Termination Kits
Step 3. Installing the Vent System
A. Vent System Approvals
These models have 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.
These models use SL-D-series, direct vent components
when using the TOP vent collars. This pipe is tested and
listed as an approved component of the appliance. 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.
These models also use DVP-series direct vent components
when using the REAR vent collars.
The flame and ember appearance may vary based on the
type of fuel burned and the venting configuration used.

WARNING: YOU MUST NOT MIX DVP-SERIES
AND SL D-SERIES COMPONENTS IN ANY VENT
SYSTEM CONFIGURATION.
Identifying Vent Components
Approved vent system components are labeled for identifi-
cation. NO OTHER VENTING SYSTEMS OR COMPO-
NENTS MAY BE USED. Detailed installation instructions
are included with each vent termination kit and should be
used in conjunction with this Installers Guide. Figure 8
shows vent system components and terminations.
The vent systems installed on this gas appliance 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. Maximum and minimum rise to run ratios
must always be maintained in the vent system when
using 45° elbows.

MUST be a 25% reduction
in total H when using the snorkel
cap except when using the simple
up and out installation (see Fig. 9)
