CSDV Series Direct Vent Gas Stove | Venting installation |
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 pipe level or downward. This may cause excessive temperatures which could cause a fire.
You may use up to three 90° elbows in this vent configuration. Refer to Horizontal Termination Configurations on Page 16.
FOR VERTICAL TERMINATION
Measure the distance from the stove 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 roof line. You may use one or two 90° elbows in this vent configuration. Refer to Vertical Termination Configurations on Page 18.
NOTE: You may use two 45° elbows in place of a 90° elbow. You must follow rise to run ratios when using 45° elbows. The appliance is approved for use with three 90° elbows maximum or a combina- tion of 90° and 45° elbows up to a maximum of 270°.
For
You may use a chase with a vent termination with exposed pipe on the exterior of the house. Refer to Installing Vent System in a Chase below.
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 A VENT SYSTEM IN AN OUTSIDE CHASE
A chase is a vertical boxlike structure built to enclose venting that runs along the outside of a build- ing. A chase is required for such venting.
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 clearance between vent pipes and combustible materials such as insulation is 1".
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.
WARNING
Always maintain minimum clearances around vent systems. The minimum clearances to combustibles for horizontal vent pipe are 2" at the top and 1" at the sides and bottom of the vent system. For wall firestops, a 1" minimum clearance all around the pipe must be maintained. Do not pack the open air spaces with insulation or other materials. This could cause high temperatures and may present a fire hazard.
