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.
Appliance QVI-25FB is approved with vent termination kits
LINK-DV-30, LINK-DV-30B, LINK-DV4-30 and LINK-DV4-30B
as shown in Figures 3 & 4. Approved vent system termina-
tions are labeled for identification. 3-inch diameter 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 COMPONENTS MAY
BE USED. Detailed installation instructions are included
with each vent termination kit and should be used in con-
junction 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 Figure 3.
NOTE:
The minimum vertical rise (exhaust vent) is 14 feet
and the maximum vertical rise is 50 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 require one (1) length of 3” stainless steel liner, 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) Termination Cap.
!
NOTE:
The damper of the existing chimney may need to be
removed to allow installation of the flexible-vent pipe.
WARNING: THIS APPLIANCE HAS BEEN CON-
VERTED FOR USE WITH A GAS APPLIANCE
INSERT ONLY AND CANNOT BE USED FOR BURN-
ING WOOD OR SOLID FUELS UNLESS ALL ORIG-
INAL PARTS HAVE BEEN REPLACED, AND THE
FIRELACE REAPPROVED BY THE AUTHORITY
HAVING JURISDICTION.
NOTE:
The above label, located in the instruction package,
must be affixed to the existing appliance prior to installation.
For zero clearance factory built woodburning appliances,
the use of kit LINK-ZC-ADB in place of the standard square
flashing will allow you to mount the adaptor and cap on
class “A” metal pipe.
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. Secure the assembly in place using one screw to
the center bracket (see Figure 4).
