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.

Vent System Approvals

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.
