Venting Installation
Instructions
WARNING: Read all instruc- tions completely and thoroughly before attempting installation. Failure to do so could result in serious injury, property damage or loss of life.
WARNING: Seal all connec- tions with high temperature silicone every time a vent con- nection is made. Before joining elbows or pipes, apply a bead of high temperature silicone sealant to the male end of the elbow or pipe. High temperature silicone must also be used to re- seal any connections after main- tenance to venting system.
NOTICE:Failuretofollowthesein- structions will void the warranty.
NOTICE: Do not seal termination cap to vent pipe. Cap must be removable for vent inspection and maintenance.
Installation Precautions
Consult local building codes before beginning the installation. The installer must make sure to select the proper vent system for installation. Before installing vent kit, the installer must read this fireplace manual and vent kit instructions.
Only a qualified service person should install venting system. The installer must follow these safety rules:
•Wear gloves and safety glasses for protection
•Use extreme caution when using ladders or when on roof tops
•Be aware of electrical wiring locations in walls and ceilings
The following actions will void the warranty on your venting system:
•Installation of any damaged venting component
•Unauthorized modification of the venting sys- tem (Do not cut or alter vent components)

INSTALLATION PLANNING
There are two basic types of
•Horizontal Termination
•Vertical Termination
It is important to select the proper length of vent pipe for the type of termination you choose. It is also important to note the wall thickness.
For Horizontal Termination: Select the amount of vertical rise desired. The horizontal run of venting must have 1/4" rise for every 12" of run towards the termination.
WARNING: Never run the vent downward as this may cause excessive temperatures which could cause a fire.
You may use one or two 90° elbows in this vent configuration. See Horizontal Termination Con- figurations on page 13.
For Vertical Termination: Measure the distance from the fireplace flue outlet to the ceiling. Add the ceiling thickness, the vertical rise in an attic or second story, and allow for sufficient vent height above the roof line. You may use one or two 90° elbows in this vent configuration. See Vertical Termination Configurations on page 16.
Note: You may use two 45° elbows in place of a 90° elbow. You must follow rise to run ratios when using 45° elbows.
For
You may use a chase with a vent termination with exposed pipe on the exterior of the house. See In- stalling Vent System in a Chase, page 11.
