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. All horizontal run of venting must have 1/4" rise for every 1"
of run towards the termination.
You may use up to three 90° elbows in this vent configuration. Refer to Horizontal Termination Configu-
rations on Pages  and 3.
For vertIcal terMInatIon
Measure the distance from the fireplace floor to the ceiling. Add the ceiling thickness, the vertical rise in
an attic or second story, and allow for sufficient vent height above the roof line.
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 combination
of 90° and 45° elbows up to a maximum of 70°.
For two-story applications, firestops are required at each floor level. 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. Refer to
Installing Vent System in a Chase below. If pipe is enclosed in chase, it is not exposed.
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 building.
A chase is required for such venting.
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.
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. Insulation should be considered
a combustible material. Maintain proper
clearances to all combustible materials.

never run the vent pipe down. this may cause
excessive temperatures which could cause a
fire.
