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.
Model:
Vent System
CFX-ZC
LINK-DV30, LINK- DV4-30
Table 1
Table 1 and Figures 3 through 5 show the vent termination
caps and systems approved for use with these models.
Approved vent system terminations are labeled for identifi-
cation. 3-inch diameter listed flexible aluminum and stain-
less steel gas vent is used for both the incoming combus-
tion air and exhaust vent pipes. NO OTHER VENTING SYS-
TEMS OR COMPONENTS MAY BE USED. Detailed in-
stallation instructions are included with each vent termina-
tion 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 or it can terminate inside the chimney. 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, 4 and 5.
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 3.
Vent System Approvals
!
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 3” collar to the end of the flexible vent pipe for exhaust
using 3 screws. Attach provided 3’ section of stainless steel
flexible vent pipe to this collar. Slide the gas insert into
place, and position any excess flexible vent pipe back up
into the chimney.
NOTE:
The 3’ section of stainless steel flexible pipe may
be cut to aid installation provided that a minimum of 2’ is
maintained.
Using the provided T-handle pull down tool, reach through
exhaust opening in exhaust collar by its center pin. Pull
down until exhaust collar (or collar attachment bracket)
extends through exhaust opening. The collar should slip fit
through the molded 3 inch opening. Carefully readjust liners
to align if necessary.
Secure in place by sliding retainer pin through the provided
holes in the exhaust collar. See Figure 4.
