INSTALLATION

DURA-VENT

HORIZONTAL

TERMINATIONS

1)Set the unit in its desired location. Check to determine if wall studs or roof rafters are in the way when the venting system is attached. If this is the case, you may want to adjust the location of the unit.

2)Direct Vent pipe and fi ttings are designed with special twist-lock connections to connect the venting system to the appliance fl ue outlet. A twist-lock appliance adaptor is installed on the unit at the factory.Assemble the desired combination of pipe and elbows to the appliance adaptor with pipe seams oriented towards the wall or ceiling, as much out of view as possible. The fi nal positioning of the pipe and 90o elbow assembly is determined by the mounting orientation of the adaptor on the stove and twist-locked for a solid connection.

Note:

a)Twist-lockprocedure:Four indentations, located on the female ends of pipes and fi ttings, are designed to slide straight onto the male ends of adjacent pipes and fi ttings, by orienting the four pipe indentations so they match and slide in to the four entry slots on the male ends (diagram 1). Push the pipe sections completely together, then twist-lock one section clockwise approximately one-quarter turn, until the two sections are fully locked. The female locking lugs will not be visible from the outside on the Black Pipe or fi ttings. They may be located by examining the inside of the female ends.

NOTE: For best results and optimum performance with each approved venting system, it is highly recom- mended to apply “Mill-Pac” sealant (supplied) to every inner pipe con- nection. Failure to do so may result in drafting or performance issues not coveredunderwarranty.Silicone(red RTV) is optional.

Note:

a)The horizontal run of vent should have a 1/4 inch rise for every 1 foot of run towardsthetermination.Neverallowthe vent to run downward. This could cause high temperatures and may present the possibility of a fi re.

b)The location of the horizontal vent termination on an exterior wall must meet all local and national building codes, and must not be blocked or obstructed. See instructions in the "External Vent Terminal Locations" section.

c)Snorkel Terminations:

For installations requiring a vertical rise on the exterior of the building, 14-inch and 36-inch tall Snorkel Terminations as shown in Dia. 3 are available, as well as the standard Riser Vent, see Dia. 3a. Follow the same installation procedures as used for standard Horizontal Termination. NEVER install the snorkel upside down.

Hint: Apply silicone to female end.

b)Horizontal runs of vent must be supported every three feet. Wall straps are available for this purpose.

3)With the pipe attached to the stove, slide the stove into its correct location, and mark the wall for a 10" x 10" (inside dimensions) square hole. The center of the square hole should line up with the centerline of the horizontal pipe, as shown in diagram 2. Cut and frame the 10 inch square hole in the exterior wall where the vent will be terminated. If the wall being penetrated is constructed of non-combustible material, i.e.masonryblockorconcrete,a7"diameter hole is acceptable.
