Step 1. Install ng 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 T THE
UTSIDE AND MUST NEVER BE ATTACHED T A
CHIMNEY SERVING A SEPARATE S LID FUEL
BURNING APPLIANCE. EACH GAS APPLIANCE
MUST USE A SEPARATE VENT SYSTEM. C MM N
VENT SYSTEMS ARE PR HIBITED.
Models: Vent System
CFX-IN LINK-DV30 LINK- DV4-30
CFX-GRAND LINK-DV30 LINK-DV4-30
Table 1
Table 1 and Figures 4 through 6 show the vent termination
caps and systems approved for the 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 (LINK -DV30) or it can terminate inside the chimney
(LINK-DV4-30). 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 4 5
and 6.
N TE: 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.
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.
N TE: 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.
N TE: 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

Step 7. Install ng Logs and Ember Mater al
Positioning the Logs
The logs for models CFX-IN and CFX-Grand have been
packaged separately. Refer to the installation instructions
that accompany this manual. Save the log instructions
with this manual.
If sooting occurs the logs might need to be repositioned
slightly to avoid excessive flame impingement.
Placing the Ember Material
Three separate bags of ember material are shipped with
this gas appliance. The bag labeled Golden Ember (GE-
93) is flame colorant material. The bags labeled Glowing
Ember (050-721) is standard glowing ember material.
To place the ember material:
 Remove the glass door from the unit (see Figure 10).
Figure 10.
Glass Assembly (CFX-IN shown)
Place a dime size piece of glowing ember material near
port holes in burner top sides and front (see Figure 11).
Figure 11. Placement of the Ember Material
 Space ember pieces about a 1/2 inch apart.
 Never press embers into burner ports.
 Cover the top of the burner with a single layer of ember
material. Then sprinkle GE-93 (Golden Ember) on top of
the burner.
 Save the remaining ember materials for use during fire-
place servicing. The embers provided are sufficient for 2
to 4 applications.
 Replace the glass door.
 Re-install and latch the glass door.
Combustible materials MUST
NEVER overlap onto the front
face.
1. Find the coiled low voltage wires
and ON/OFF switch attached to
outer right side of the insert. See
Figure 12 (Model CFX-IN shown).
2. Disconnect the ON/OFF switch
from the low voltage wire leads
and insert the ON/OFF switch
through the hole at the upper
right corner of the surround - it
will be retained in the hole.

Step 9. Before L ght ng the Appl ance
Before lighting the appliance be sure to do the following:
Remove all paperwork from underneath the fireplace.
Review safety warnings and cautions
 Read the Safety and Warning Information section at
the beginning of this Installers Guide.
Double-check for gas leaks
 Before lighting the appliance double-check the unit for
possible gas leaks.
Double-check vent terminations for obstructions.
 Before lighting the appliance double-check the unit for
possible obstructions that could be blocking the vent ter-
minations.
Double-check for faulty components
 Any component that is found to be faulty MUST BE re-
placed with an approved component. Tampering with the
appliance components is DANGER US and voids all war-
ranties.
A small amount of air will be in the gas supply lines. When
first lighting the appliance it will take a few minutes for the
lines to purge themselves of this air. Once the purging is
complete the appliance will light and will operate normally.
Subsequent lightings of the fireplace will not require this
purging of air from the gas supply lines unless the gas
valve has been turned to the FF position in which
case the air would have to be purged.
N TE: The fireplace should be run 3 to 4 hours on the initial
start-up. Turn it off and let it cool completely. Remove and
clean the glass. Replace the glass and run the fireplace for
an additional 8 hours. This will help to cure the chemicals
used in the paint and logs.
Step 10. L ght ng the Appl ance
Youve reviewed all safety warnings youve checked the
appliance for gas leaks you know the vent system is
unobstructed and youve checked for faulty components.
Now youre ready to light the appliance.
WARNING: PLEASE REFER T THE USERS
MANUAL F R ALL CAUTI NS, SAFETY, AND
WARNING INF RMATI N PERTAINING T THE
LIGHTING AND PERATI N F THE APPLIANCE.
After the Installat on
LEAVE THIS INSTALLATI N MANUAL WITH
THE APPLIANCE F R FUTURE REFERENCE.

3. Reconnect the low voltage wires to the ON/OFF switch.
4. Attach surround assembly by hooking the support brack-
et on the locating tabs on top of the gas insert fireplace
(see Figure 12.) Once the surround assembly is on the
locating tabs ensure the bottom hooks are resting on
the locating pins at the base. Reposition the fireplace if
necessary. Refer to surround instructions provided with
the decorative surround.
N TE: PLACE THE THREE INSULATI N PIECES INT
THE CAVITIES AT THE BACK F THE SURR UND BE-
F RE P SITI NING THE INSERT INT THE FACT RY-
BUILT R MAS NRY FIREPLACE. THIS INSULATI N
WILL HELP SEAL F R C LD AIR LEAKS.

4Maintaining and Servicing Your Appliance
Appl ance Ma ntenance
Although the frequency of servicing and maintenance will
depend on use and the type of installation you should have
a qualified service technician perform an appliance check-
up at the beginning of each heating season. See the table
below for specific guidelines regarding each fireplace main-
tenance task.
IMP RTANT: TURN FF THE GAS BEF RE SERVICING
Y UR FIREPLACE.
Replacing old ember material
Frequency: Once annually during the checkup.
By: Qualified service technician.
Task: Brush away loose ember material near the burner.
Replace old ember material with new dime-size and shape
pieces of Golden Ember (DE-93) and Glowing Ember (050-
721). New ember material should be placed alternately on
top of the burner - a layer of Golden Ember a layer of
Glowing Ember and so on. Save the remaining ember
material and repeat this procedure at your next servicing.
For more information see Placing Ember Material.
Cleaning Burner and Controls
Frequency: Once annually.
By: Qualified service technician.
Task: Brush or vacuum the control compartment fireplace
logs and burner areas surrounding the logs.
Checking Flame Patterns, Flame Height
Frequency: Periodically.
By: Qualified service technician/Home owner.
Task: Make a visual check of your fireplaces flame patterns.
Make sure the flames are steady - not lifting or floating.
See Figure 14. The thermopile/thermocouple (standing pilot)
