Step 3. Installing the Vent System
A. Vent System Approvals
These models are approved to use DVP series direct vent pipe components and terminations (see Figures 6 and 7). Approved vent system components are labeled for identifi- cation. This pipe is tested and listed as an approved com- ponent 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 SYS-
TEMS 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 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. Rise to run ratios in the vent system must be followed if 45° elbows are used.
This model has 450 elbow built into this unit. It may be positioned to vent either horizontal or vertical. Depending on the installation, decide which direction the elbow should be facing. Remove the 8 screws from the corner cover plate. Position the 450 elbow as desired and replace the corner cover plate with the 8 screws.
