Step 3. Installing the Vent System
A. Vent System Approvals
These models are approved to use
NENTS 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 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 relation- ships 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.
