Section M- K-300 Fireplace Insert

Installation Instructions

With the addition of a fireplace insert surround kit (part # W-KWSK) your K-300/K-400 unit may be installed and used in masonry fireplaces only (lined, masonry chimneys constructed in accordance with NFPA 211 guidelines). NOT APPROVED FOR USE IN FACTORY– BUILT OR ZERO CLEARANCE FIREPLACES. If your masonry chimney is damaged, deteriorated, or unlined, a stainless steel liner (8” diameter) with thermal wrap will need to be installed and connected directly to the K-300 flue opening. If you are unsure of the condition of your chimney, have it inspected by your dealer or a chimney professional. Use and install liner kits that are approved to UL 1777 only. If your masonry fireplace/chimney is in good shape, your K-300 is approved for installation and use with or without a direct-connect liner system. There is no replacement for a proper draft to ensure optimum performance from your K-300, so a stainless steel liner could be necessary for a proper draft. As a general guideline, if the flue area (interior dimensions) of your chimney is 100 sq. inches or less, your insert should draft fine. Due consideration of all conditions that could affect draft such as chimney height, geographical conditions, location, climate, etc. should be noted. Contact your dealer with any questions.

PRELIMINARY CHECKS:

*A preliminary check of the chimney should be made. Check for any obstructions, cracks, or deterioration. If there is any evidence of deterioration of any kind, repairs should be made before installation. Also check for excess creosote build up and clean if necessary. If a stainless steel liner system is being used, install according to the liner manufacturer’s instructions.

*Make sure the damper in your fireplace is in the full open position or removed before installing the insert. Also make sure there is no danger of the damper handle closing accidentally or that installation of the insert would bump the handle closed.

*Double check the drop in the fireplace from the hearth measured down to the bottom of the firepit are. Check to make sure you have the proper height roller or pipe (see fig. 6) needed to roll the insert into place. Option: 2– 3/8” N.C. bolts of appropriate lengths may be screwed into the threaded holes at the insert bottom rear corners for the “drop” in the firepit area if necessary. A piece of sheet metal laid in the firepit bottom will be helpful so the bolt heads can slide easily as the insert is being pushed in.

*Determine the position of the faceplate.
