TRIM AND MANTEL INSTALLATION FOR WOOD BURNING FIREPLACES
• The fireplace face may be left exposed or trimmed. If trim is installed, fasten it securely to face of fireplace. Seal any
cracks between trim material and face of fireplace. Cracks can cause a fire and prevent fireplace from working prop-
erly.
• Place wall ties in mortar joints of masonry trim. Fasten wall ties to face of fireplace with sheet metal screws.
• Use only non-combustible materials below top of spacers.
Seal any space between face of
fireplace and non-combustible facing
material. Failure to seal this crack is a
possible fire hazard and will void the
warranty.

opening. Combustible materials may be placed within shaded
areas. Note: Do not let combustible materials overlap
black painted surface more than 1 /
8
". See Figure 41.
Trim may butt against side walls of fireplace. The other 3 walls
must have ¾" clearances.
