FIREPLACE TRIM KIT
Our Fireplace Trim Kit is designed for both the look and function for
that perfect nish. A 7 piece trim kit: 2 Base Blocks, 2 Columns, a left
and right header, and a key stone. Each section of the trim kit is manu-
factured with metal brackets for ease of installation.
The Fireplace Trim Kit is a universal size, which can be cut to t most
replaces. Hearth Stones are sold separately.
STEP 1:
Choose the type and size of insert you are going to use and write
down the dimensions.
STEP 2:
Next frame out your replace using traditional 2”x4”s and wrap in either plywood, concrete board or
other rigid sheathing. Next you will strike several horizontal chalk lines to help you keep your starter
strips level.
STEP 3:
Measure your hearth’s depth and width to determine the number of Heart Stones needed. Now for
your Trim Kit. Start by placing the hearth stone rst, next place the base block and one column on
top of that. Mark the columns height needed and cut to size using a masonry blade. Attach both
side bases and columns. Center and attach the Keystone. Now place the right and left headers
trimming to size needed.
STEP 4:
When inside and/or outside corners are present it is recommend that you start with inside
corners rst, then outside corners, then ll in between with ats. The rst row locks onto
the Starter Strip and the stones work better from left to right. When you get to the end of
the each row measure and make the appropriate cut, using the remaining piece to begin
your next row.
STEP 5: FINISHING
Cutting may be necessary to nish the top row. If you have to make any cuts, do not cut
the bottom section of the rail on the stone, so that it can still be locked into place. Make
your cut and set the stone into place to assure the t. Once you are condent that your t
is correct, use a quality Construction Adhesive. Apply the desired amount to the top and
back section and along each vertical butt joint, ensuring that the stone is locked into place.
