VENTING INSTALLATION
WARNING: Read all instructions completely and thoroughly before attempting installation. Failure to do so could result in serious injury, property damage or loss of life. Operation of improperly installed and maintained venting system could result in serious injury, property damage or loss of life.
WARNING: Seal all pipe to pipe connections with high temperature silicone (600°F/316° C) every time a vent connection is made. Before joining elbows and pipes, apply a bead of high temperature silicone sealant (GE RTV 106/Loctite RTV 81585) to the male end of the elbow or pipe. High temperature silicone must also be used to reseal any connections after maintenance to venting system.
NOTICE: Do not seal termination cap to pipe. Cap must be removable for servicing vent system.
NOTICE: Failure to follow these instructions will void the warranty.
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 installer or 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 system
•Installation of any component part not manufactured or approved by DESA International
•Installation other than as instructed by these instructions
WARNING: This gas fireplace and vent assembly must be vented directly to the outside. The venting system must NEVER be attached to a chimney serv- ing a separate solid fuel burning appliance. Each gas appliance must use a separate vent system. Do not use common vent systems.
WARNING: Horizontal sections of this vent sys- tem require a minimum clearance of 2" from the top of the vent pipe and 1" minimum to the sides and bottom. Vertical sections of this system require a minimum of 1" clearance to combustible materials on all sides of the vent pipe.
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 Configurations on page 12.
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 roofline. You may use one or two 90° elbows in this vent configuration. See Vertical Termination Configurations on pages 14 and 15.
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 Installing Vent System in a Chase, page 10.
Your Vanguard
It is very important that the venting system maintain its balance between the combustion air intake and the flue gas exhaust. Certain limitations apply to vent configurations and must be strictly followed.
