OWNER’S MANUAL

VENTING INSTALLATION

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. Operation of im- properly installed and maintained venting system could result in serious injury, property damage or loss of life.

WARNING: Seal all of the outer pipe connections with high tem- perature silicone (600°F/316° C) every time a vent connection is made. Before joining elbows and pipes, apply a small bead of high temperature silicone sealant (GE RTV 106/Loctite RTV 81585) to the outer section of male end of the elbow or pipe. High tempera- ture silicone must also be used to re-seal any connections after maintenance to venting system.

NOTICE: Failure to follow these instructions will void the warranty.

INSTALLATION

PRECAUTIONS

Consult local building codes before begin- ning 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 war- ranty on your venting system:

Installation of any damaged venting component

Unauthorized modification of the vent- ing 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 serving a separate solid fuel burning ap- pliance. Each gas appliance must use a separate vent system. Do not use common vent systems.

WARNING: Horizontal sec- tions of this vent system require a minimum clearance of 2" from the top of the vent pipe and 1" minimum to the sides and bot- tom. Vertical sections of this sys- tem require a minimum of 1" clear- ance to combustible materials on all sides of the vent pipe.

INSTALLATION PLANNING

There are two basic types of direct-vent installation:

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 horizon- tal 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 ex- cessive temperatures which could cause a fire.

You may use one or two 90° elbows in this vent configuration. See Horizontal Termina- tion Configurations on pages 10 and 11.

For Vertical Termination: Measure the distance from the fireplace flue outlet to the ceiling. Add the ceiling thickness, the verti- cal 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 13 and 14.

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 two-story applications, firestops are re- quired at each floor level. If an offset is needed in the attic, additional pipe and el- bows will be required.

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, below.

Your Vanguard direct-vent fireplace has been tested for a minimum 3' rise with a maximum 10" wall thickness. The maxi- mum horizontal run is 20' with 8' vertical rise (see Installation for Horizontal Termi- nation, page 8). The maximum vertical run is 30' (seeInstallation for Vertical Termina- tion, page 12).

It is very important that the venting system maintain its balance between the combus- tion air intake and the flue gas exhaust. Certain limitations apply to vent configura- tions and must be strictly followed.

Installing Vent System in a Chase

A chase is a vertical box-like structure built to enclose venting that runs along the out- side of a building. A chase is not required for such venting.

NOTICE: Treatment of firestops and construction of the chase may vary from building type to build- ing type. These instructions are not substitutes for the require- ments of local building codes. You must follow all local building codes.

Note: When installing in a chase, you should insulate the chase as you would the outside walls of your home. This is especially im- portant in cold climates. Minimum clear- ance between vent pipes and combustible materials such as insulation is 1".

After framing the chase (see Framing on pages 4 and 5) install the vent system by following the installation instructions.
