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
The flame and ember appearance may vary based on the type of fuel burned and the venting configuration used.
!WARNING: YOU MUST NOT MIX
Identifying Vent Components
Approved vent system components are labeled for identifica- tion. This pipe is tested and listed as an approved compo- nent of the fireplace. The pipe is tested to be run inside an enclosed wall. There is no requirement for inspection open- ings at each joint within the wall. There is no required pitch for horizontal vent runs. 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. Fig- ure 7 shows vent system components and terminations.
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. Maximum and minimum rise to run ratios must always be maintained in the vent system when using 45° elbows.
