Trim And Mantel Installation For Wood Burning Fireplaces; Locating Front And Side Clearances - Monessen Hearth BWBC400MHB Installation And Operating Instructions Manual

TRIM AND MANTEL INSTALLATION FOR WOOD BURNING FIREPLACES

• The fireplace face may be left exposed or trimmed with
material such as brick, stone, or marble. 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 properly.
Block the fireplace with framing and attach the base to the
supporting floor to reduce the possibility of such a crack
developing.
• Place wall ties in mortar joints of masonry trim. Fasten
wall ties to face of fireplace with sheet metal screws.
• Do not install combustible materials below the top spac-
ers of the fireplace. Do not allow combustible materials to
overlap the sides of fireplace face. Seal face of fireplace
to surrounding wall with noncombustible caulk or trim
materials. This will prevent cold air leaking around the
fireplace. See Figure 23.
• Use only non-combustible materials below top of spac-
ers.
• The trim must not block or restrict in any way the flow of
air through the air inlet and air outlet louvers in the face
of the fireplace.

LOCATING FRONT AND SIDE CLEARANCES

To find front clearances, extend a line from back corner of unit
to 4" in front of fireplace face and 1" outside screened opening.
Combustible materials may be placed within shaded areas.
Note: Do not let combustible materials overlap black
painted surface more than
Trim may butt against side walls of fireplace. The other 3 walls
must have ¾" clearances.
To avoid interference with glass doors, do not allow non-
combustible decorative trim to extend closer than
vertical edges of the firebox opening.

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.
Do not block or restrict air inlets or
air outlets. Blocking or restricting air
inlets or air outlets could cause a fire
hazard.
