Step 4
Installing the
Vent System
A. Vent System Approvals
Models R-3500TV, R-4500TV are approved to use 5-
inch (127mm) diameter B-type vent. Model R-6500TV
is 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 7.
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 at the vent pipe through the holes in the
10 5/8 ring 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
vertical position, and a
MINIMUM
9-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 15 FEET FOR THE ENTIRE VENT
SYSTEM.
