CAST IRON STOVE AND BURNER SYSTEM

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 vent con- nections. Seal only the outer pipe connectionswithhightemperature silicone (600°F/316°C). Before join- ing elbows and pipes, apply a bead of high temperature silicone seal- ant(GERTV106/LoctiteRTV81585) to the male end of the elbow or pipe. High temperature 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 stove and burner system manual and vent kit instructions.

Only a qualified service person should in- stall venting system. The installer must fol- low 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 stove with burner system and vent assembly must be vented directly to the out- side. The venting system must NEVER be attached to a chimney serving a separate solid fuel burn- ing appliance. 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 pipe and 1" mini- mum to the sides and bottom. Vertical sections of this system require a minimum of 1" clear- ance to combustible materials on all sides of the 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 pipe 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 Termina- tion Configurations on pages 13 and 14.

For Vertical Termination: Measure the dis- tance from the burner system 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 Ter- mination Configurations on pages 16 and 17.

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 elbows will be required (see Figure 31, page 15).

You may use a chase with a vent termina- tion with exposed pipe on the exterior of the house. See Installing Vent System in a Chase, below.

Your Comfort Glow stove with direct-vent burner system has been tested for a maxi- mum 17" wall thickness when using a 60º elbow directly off the back of the stove. The maximum horizontal run is 20' with 8' ver- tical rise (see Installation for Horizontal Termination, pages 11 and 12). The maxi- mum vertical run is 30' (seeInstallation for Vertical Termination, pages 14 and 15).

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 boxlike 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 building type. These instructions are not substitutes for the re- quirements 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".
