Quadra-Fire • QVI-25FB • 2031-900 Rev. F • 9/07103 Installing the InsertStep 1. Installing the Vent SystemVent System Installation PrecautionsBefore starting installation of vent kits, the installer shouldread these instructions and the Vent Kit Instructions toensure that a proper vent installation is completed.Consult your local building codes before beginning theinstallation.WARNING: THIS GAS INSERT AND VENT AS-SEMBLY MUST BE VENTED DIRECTLY TO THEOUTSIDE AND MUST NEVER BE ATTACHED TO ACHIMNEY SERVING A SEPARATE SOLID FUELBURNING APPLIANCE. EACH GAS APPLIANCEMUST USE A SEPARATE VENT SYSTEM. COMMONVENT SYSTEMS ARE PROHIBITED.Appliance QVI-25FB is approved with vent termination kitsLINK-DV-30, LINK-DV-30B, LINK-DV4-30 and LINK-DV4-30Bas shown in Figures 3 & 4. Approved vent system termina-tions are labeled for identification. 3-inch diameter listedflexible aluminum and stainless steel gas vent is used forboth the incoming combustion air and exhaust vent pipes.NO OTHER VENTING SYSTEMS OR COMPONENTS MAYBE USED. Detailed installation instructions are includedwith each vent termination kit and should be used in con-junction with this manual.Horizontal VentingThe vent system on this model CANNOT be terminatedhorizontally.Vertical VentingThe vent pipes MUST be connected to the proper collarson the unit AND the exhaust vent pipe MUST be connectedto the termination cap or the unit will not operate. The com-bustion air vent pipe CAN be connected to the terminationcap (LINK -DV30, LINK -DV30B) or it can terminate insidethe chimney (LINK-DV4-30, LINK-DV4-30B). The bottomopening of the chimney must be sealed around the ventpipes if the combustion air vent is NOT connected to thetermination cap. See Figure 3.NOTE: The minimum vertical rise (exhaust vent) is 14 feetand the maximum vertical rise is 50 feet. These dimensionsare measured from the starting collars of the unit to the endof the last section of vent pipe. See dimension V in Figure 3.Vent System Approvals!A vertical vent termination system installed on this modelwill 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 beremoved to allow installation of the flexible-vent pipe.WARNING: THIS APPLIANCE HAS BEEN CON-VERTED FOR USE WITH A GAS APPLIANCEINSERT ONLY AND CANNOT BE USED FOR BURN-ING WOOD OR SOLID FUELS UNLESS ALL ORIG-INAL PARTS HAVE BEEN REPLACED, AND THEFIRELACE REAPPROVED BY THE AUTHORITYHAVING 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 squareflashing will allow you to mount the adaptor and cap onclass “A” metal pipe.Connecting the Vent PipeInstall the 3” flexible vent pipe(s) down through the chimney.Secure the end of the flexible vent pipe for exhaust to theprovided 3’ section of stainless steel flexible vent pipe. A 3”collar is factory installed on one end for mating the twoends of flexible pipe.WARNING: THE 3’ SECTION OF STAINLESSSTEEL 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 intakecollar on the collar slide-plate using 3 screws. This assemblymay be removed from the unit to aid installation. Slide insertinto position, while pulling intake collar assembly towardsthe front of the unit. Slide the gas insert into place, andposition any excess flexible vent pipe back up into thechimney. Secure the assembly in place using one screw tothe center bracket (see Figure 4).!
