Installation of Gas Appliance in Fireplace
TRIM INSTALLATION
The face of your fireplace may be left exposed or trimmed with any noncombustible material such
as brick, stone or marble.
Figure 30.
If a noncombustible trim is installed, be sure it is fastened
snugly to the face of the fireplace. A crack between the material and the face of the fireplace could
pose a fire hazard and impair the proper operation of the fireplace. Blocking the fireplace with fram-
ing and attaching the base to the supporting floor will further reduce the possibility of such a crack
developing.
CAUTION:
Do not allow any trim materials to extend closer than 3/8” to the vertical edges of the
firebox opening if you plan to equip the fireplace with glass doors.
Wall ties should be fastened to the face of the fireplace with sheet metal screws and placed in the
mortar joints of masonry trim.
Combustible material must not be installed below the top spacers of the fireplace or overlap the
sides of the fireplace face. Seal the face of the fireplace to the surrounding wall with noncombus-
tible caulk or trim materials to prevent cold air leakage around the fireplace.
CAUTION:
No trim should block or restrict in any way the flow of air into the air inlets in the face of
the fireplace.
