Installing the Insert
Step 1. Installing the Vent System
Vent System Installation Precautions
Before starting installation of vent kits, the installer should
read these instructions and the Vent Kit Instructions to
ensure that a proper vent installation is completed.
Consult your local building codes before beginning the
installation.
WARNING: THIS GAS INSERT AND VENT AS-
SEMBLY MUST BE VENTED DIRECTLY TO THE
OUTSIDE AND MUST NEVER BE ATTACHED TO A
CHIMNEY SERVING A SEPARATE SOLID FUEL
BURNING APPLIANCE. EACH GAS APPLIANCE
MUST USE A SEPARATE VENT SYSTEM. COMMON
VENT SYSTEMS ARE PROHIBITED.
Models CFX-Grand-B, CFX-IN-B, FB-IN and FB-GRAND is
approved with vent termination kits LINK-DV-30, LINK-DV-
30B, LINK-DV4-30 and LINK-DV4-30B. Approved vent sys-
tem terminations are labeled for identification. 3-inch diam-
eter listed flexible aluminum and stainless steel gas vent is
used for both the incoming combustion air and exhaust
vent pipes. NO OTHER VENTING SYSTEMS OR COM-
PONENTS MAY BE USED. Detailed installation instruc-
tions are included with each vent termination kit and should
be used in conjunction with this manual.
Horizontal Venting
The vent system on this model CANNOT be terminated
horizontally.
Vertical Venting
The vent pipes MUST be connected to the proper collars
on the unit AND the exhaust vent pipe MUST be connected
to the termination cap or the unit will not operate. The com-
bustion air vent pipe CAN be connected to the termination
cap (LINK -DV30, LINK -DV30B) or it can terminate inside
the chimney (LINK-DV4-30, LINK-DV4-30B). The bottom
opening of the chimney must be sealed around the vent
pipes if the combustion air vent is NOT connected to the
termination cap. See Figures 3 and 4.
NOTE: The minimum vertical rise (exhaust vent) is 14 feet
and the maximum vertical rise is 40 feet. These dimensions
are measured from the starting collars of the unit to the end

of the last section of vent pipe. See dimension V in Figure 4.
A vertical vent termination system installed on this model
will include one (1) length of 3-inch flexible vent pipe for the
combustion air, one (1) length of 3-inch flexible vent pipe for
the exhaust air, one (1) pipe-to-cap adaptor, and one (1)
SLK-991DA or SLK-980D Vertical Termination Cap.
!
NOTE: The damper of the masonry chimney may need to
be removed to allow installation of the flexible-vent pipe.
This fireplace has been altered to accommodate an
insert and should be inspected by a qualified person
prior to re-use as a conventional fireplace.
NOTE: The above label, located in the instruction package,
must be affixed to the existing fireplace prior to installation.
For zero clearance factory built woodburning fireplaces, the
use of kit LINK-ZC-ADP in place of the standard square
flashing will allow you to mount the adaptor and cap on
metal pipe. Additionally, the use of kit FLASH-DAMP will
seal off the damper opening when terminating the inlet air
vent pipe just above the damper. These 2 kits are
recommended for zero clearance, factory built woodburning
fireplaces.
Connecting the Vent Pipe
Install the 3” flexible vent pipe(s) down through the chimney.
Secure the end of the flexible vent pipe for exhaust to the
provided 3’ section of stainless steel flexible vent pipe. A 3”
collar is factory installed on one end for mating the two
ends of flexible pipe.
WARNING: THE 3’ SECTION OF STAINLESS
STEEL FLEXIBLE PIPE MUST BE ATTACHED DI-
RECTLY TO THE EXHAUST COLLAR OF THE UNIT.
Attach either 4’ or 30’ section of intake liner to the intake
collar on the collar slide-plate using 3 screws. This assembly
may be removed from the unit to aid installation. Slide insert
into position, while pulling intake collar assembly towards
the front of the unit. Slide the gas insert into place, and
position any excess flexible vent pipe back up into the
chimney. This assembly will be secured in place when the
pull handle can be locked into position at locking brackets.
