VENTING INSTALLATION
WARNING: Horizontal sec-
tions of this vent system require
a minimum clearance of 2" from
the top of the pipe and 1" mini
-
mum to the sides and bottom.
Vertical sections of this system
require a minimum of 1" clear
-
ance 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" rise for every
12" of run towards the termination.
WARNING: Never run the
vent downward as this may
cause excessive temperatures
which could cause a fire.
You may use one or two 90° elbows in this
vent configuration. See
Horizontal Termina-
tion Configurations
on page 16.
For Vertical Termination:
Measure distance
from fireplace flue outlet to ceiling. Add ceiling
thickness, vertical rise in an attic or second
story, and allow for sufficient vent height
above roof line. You may use one or two 90°
elbows in this vent configuration. See
Vertical
Termination Configurations
on page 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. 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 exterior of house. See
