Step 4. Installing the Vent System
A. Vent System Approvals
Model ST-38GTV is approved to use 5-inch (127mm)
diameter B-type vent. B-type vent must be used when the
vent system is within combustible construction.
This model 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 diameter noted above for B-type vent must be
used for single-wall vent. See Figure 5.
B. System Components.
Vent System Configuration
MAXIMUM TOTAL HORIZONTAL RUN = 13 FT.
MAXIMUM TOTAL VERTICAL RISE = 10 FT.
MAXIMUM NO. of ELBOWS: 2 -90
o
plus 4 - 45
o
, or 8 - 45
o
.
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 always better to first
attach a straight section of vent to the unit before
attaching an elbow. Avoid using elbows in the vent
system if possible.
A 90-degree elbow can be attached directly to the unit. If it
is, it can be followed by a MAXIMUM 13-feet horizontal
run, a second 90-degree elbow ending in a vertical position,
and a MINIMUM 10-feet vertical rise ending in a listed
termination cap for the vent pipe.
Continue to add vent components, until the vent run is
completed.
WARNING: YOU MUST NOT EXCEED A TOTAL
MAXIMUM HORIZONTAL RUN OF 13 FEET FOR
THE ENTIRE VENT SYSTEM AND THERE MUST
BE A TOTAL VERTICAL MINIMUM RISE OF 10-
FEET IN ALL VENT SYSTEM CONFIGURATIONS
USED ON THESE FIREPLACES.
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.
