Facing Installation
Following the specifications listed in the section titled "LIGHTWEIGHT BLOCK-IN
SPECIFICATIONS", construct the facing following all building codes that may apply. Make
sure it adheres to all of the specifications listed. The facing should totally enclose the
masonry block-in into the chase.
NOTE: Allow the block-in to dry for at least one month
before using the fireplace. This will prevent the
block-in from cracking.
