Installation Precautions Installation Planning
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. Seal only the outer pipe connections with high tempera­ture silicone (600°F/316° C). 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 stove and burner system 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 system
• Installation of any component part not manufactured or approved by DESA
• Installation other than as instructed by these instructions
WARNING: This stove with burner system 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 appli­ance. Each gas appliance must use a separate vent system. Do not use common vent systems.
WARNING: Horizontal sections of this vent system require a minimum clearance of 2" (5.08 cm) from the top of the pipe and 1" (2.54 cm) minimum to the sides and bottom. Vertical sections of this system require a minimum of 1" (2.54 cm) clearance 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 horizontal run of venting must have 1/4" (6.35 mm) rise for every 12" (0.3 m) 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 up to two 90° elbows on any single horizontal run of vent pipe in this configuration. See Horizontal Termination Configu- rations on page 15.
For Vertical Termination: Measure the distance from the bur ner
system flue outlet to the ceilin g. 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 17 through 19.
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 required at each floor level
(see Figure 35, page 16). If an offset is needed in the attic, additional pipe and elbows 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, page 13.
Your stove with direct-vent burner system has been tested for a maximum horizontal run of 20' (6 m) with 8' (2.4 m)vertical rise (see Installation for Horizontal Termination, pages 13 through 15). The maximum vertical run is 40' (12 m) (see Installation for Vertical Termination, pages 16 through 19).
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.

Installing Vent System in a Chase
A chase is a vertical box-like structure built to enclose venting that runs along the outside 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 requirements 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 important in cold climates. Minimum air space clearance between vent pipes and combustible materials and/or insulation is 1" (2.54 cm).

CAUTION: Horizontally terminated venting con-
figurations require one foot of vertical rise from the 45° elbow before any horizontal run can be made. Failure to meet venting requirements may cause performance problems and possible damage to the fireplace.
1. Determine the route your horizontal venting will take.
location of the horizontal vent termination on the exterior wall must meet all local and national building codes and must not be blocked or obstructed.
WARNING: Do not recess vent terminal into a wall
or siding.
Snorkel terminations are available for terminations requiring a vertical rise on the exterior of the building (see Figures 24 and
25). Snorkel kit VKS-47-K is also available (see page 19). Fol­low the same installation procedures used for standard horizon­tal termination with the exception of the external wall firestop. The snorkel termination does not require the use of the external wall firestop. If installing the snorkel termination below grade (basement applications), you must provide proper drainage to prevent water from entering the snorkel termination (see Figure
25). Do not back fill around the snorkel termination.
2. V ent pipes and fittings have special twist-lock connections. As-
semble the desired combination of pipe and elbows to the appli­ance adaptor with pipe seams oriented towards the wall or floor.
Twist-loc k Procedure: The female ends of the pipes and fittings
have four locking lugs (indentations). These lugs will slide straight into matching slots on the male ends of adjacent pipes and fit­tings. (All connections must be sealed with high temperature sili­cone sealant as specified in the second warning statement on page
12.) Push the pipe sections together and twist one section clock­wise approximately one-quarter turn until the sections are fully locked. See Figure 26. supported every three feet. Use wall straps for this purpose.
