Step 4. Installing the Vent System
A. Vent System Approvals
Model SL-350TV is approved to use 4-inch (102mm)
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.
For B-type vent the clearance to combustibles is 1-inch.
Follow vent manufacturers
REQUIRED
clearances.
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
RISE TO RUN RATIO = 2:1
MAXIMUM
TOTAL HORIZONTAL RUN = 15 FT.
MINIMUM
TOTAL VERTICAL RISE = 9 FT.
MAXIMUM NO. Of ELBOWS:
2 - 90
o
or 4 - 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 through the collar from inside the unit to check that
the vent pipe is attached.
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
15-feet horizontal
run, a second 90-degree elbow ending in a minimum 30
foot vertical.
A minimum of 9 foot vertical rise ending in a listed termination
cap is required for the unit.
Continue to add vent components, until the vent run is
completed.
WARNING: YOU MUST NOT EXCEED A TOTAL
MAXIMUM HORIZONTAL RUN OF 15 FEET FOR
THE ENTIRE VENT SYSTEM.

NOTE: The vent termination must be in a vertical posi-
tion and the termination cap must be listed for the
vent pipe used.
Consult Local Building Code Officials and Codes for proper
vent system installations.
