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.
