Step 4
Installing the
Vent System
18
A. Vent System Approvals
These fireplaces are approved to use 6-inch (152mm)
diameter B-type vent. B-type vent must be used
when the vent system is within combustible
construction.
These models may also use single wall rigid or flexible
gas vent IF and ONLY IF the vent system is installed
within non-combustible construction such as a masonry
chimney. The same diameters noted above for B-type
vent must be used for single-wall vent. See Figure 6.
The flame and ember appearance may vary based on
the type of fuel burned and the venting configuration used.
B. System Components.
Vent System Configuration
MAXIMUM TOTAL HORIZONTAL RUN = 17 FT.
MINIMUM TOTAL VERTICAL RISE = 10 FT.
MAXIMUM NO. of ELBOWS: 2 - 90
Plan and install the vent system using the parameters
shown above.
WARNING: YOU MUST NOT EXCEED
!
THESE PARAMETERS.
Connect a B-Type vent component to the flue outlet
collar. Look at top inside of the firebox to check that
the vent pipe is attached to the unit. NOTE: It is
required to first attach a straight section of vent
to the unit before attaching a 90
using elbows in the vent system if possible.
A 90-degree elbow CANNOT be attached directly to
o
the unit. A 45
elbow can be attached directly to
the unit. It must have a straight section of pipe
attached to it for a MINIMUM of 4-feet before a
0
second 45
elbow to a horizontal run (see Figure 6).
The horizontal component of the vent system must
not exceed a MAXIMUM of 17-feet. The vertical
component of the vent system must exceed a
MINIMUM of 10-feet. Two 45
be used at any length within the 17-feet maximum
horizontal component.
Continue to add vent components, until the vent run is
completed.
WARNING: YOU MUST NOT EXCEED A
!
TOTAL MAXIMUM HORIZONTAL RUN OF
17 FEET FOR THE ENTIRE VENT SYSTEM.
NOTE: The vent termination must be in a vertical
position and the termination cap must be listed
for the vent pipe used.
Consult local building code officials and codes for
proper vent system installations.
