VENT INSTALLATION
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 12" of run towards the
termination.
You may use up to three 90° elbows in this vent conguration. See
Horizontal Termination Congurations on pages 23 and 24.
FOR VERTICAL TERMINATION
Measure the distance from the replace oor to the ceiling. Add the ceiling thickness, the vertical rise in an attic or second
story, and allow for sufcient 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 270°.
For two-story applications, restops are required at each oor 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. See 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 ue gas exhaust.
Certain limitations apply to vent congurations 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.
Never run the vent pipe level or
downward. This may cause excessive
temperatures which could cause
a fire.
WARNING
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.
NOTICE
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.

VENT INSTALLATION
Always maintain minimum clearances around vent systems. The minimum clearances
to combustibles for horizontal vent pipe are 3" at the top and 1" at the sides and bottom
of the vent system until the pipe penetrates the nearest vertical wall. 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.

Figure 17 - Allowable Venting Chart
HOW TO USE THE VENT GRAPH
The Vent Graph should be read in conjunction with the following
vent installation instructions to determine the relationship between
the vertical and horizontal dimensions of the vent system.
1. Determine the height of the center of the horizontal vent pipe
exiting through the outer wall. Using this dimension on the
Sidewall Vent Graph below, locate the point intersecting with
the slanted graph line.
2. From the point of this intersection, draw a vertical line to the
bottom of the graph.
3. Select the indicated dimension, and position the replace in
accordance with same.
Example: If the vertical dimension from the floor of the
fireplace is 11' (3.4m) the horizontal run to the face of the
outer wall must not exceed 14' (4.3m).
Example: If the vertical dimension from the floor of the unit
is 7’ (2.14m), the horizontal run to the face of the outer
wall must not exceed 81/2' (2.6m).
