Fireplace Size Requirements
A. Minimum Fireplace Opening
Minimum fireplace opening requirements for a standard 3/4
inch deep surround are shown in Figure 5.2. For smaller
openings, an optional 1-1/2 in. (38 mm) deep surround is
available and dimensions are shown in Figure 5.3.
WARNING!
Risk of Fire or Burns!
Provide adequate
clearance around air openings and for service access.
Due to high temperatures, the appliance should be locat
-
ed out of traffic and away from furniture and draperies.
• The firebrick (refractory), glass doors, screen rails, screen
mesh and log grates can be removed from a factory
built firebox in order to gain minimum gas insert opening
requirements.
• Any smoke shelves, shields and baffles may be removed
from the factory built firebox
if attached with mechanical
fasteners.
• The metal floor of the solid fuel firebox may be removed
to facilitate the installation of the insert.
• Cutting of any sheet metal parts of the fireplace in which
the gas fireplace insert is to be installed is prohibited,
except the floor as tested for and as noted above and in
Figure 5.1.
• A minimum 1/2 in. (13 mm) gap from the bottom of the
appliance to the metal floor of the solid fuel firebox is
RECOMMENDED
for optimal fan performance. See
side view in Figure 5.1

• The appliance may not be placed directly on the base
of the outer wrap, a 1/4 in. (6 mm) airspace
MUST
be provided between the insert and the floor of the
outer wrap. Use the leveling legs to raise the insert a
minimum of 1/4 inch. The original fireplace may never
be returned to solid fuel in this condition. The sidewalls
and top structure of the firebox may not be altered with
the exception of removable baffles and dampers.
• If a minimum 1/2 in. (13 mm) gap can not be achieved,
a section of the factory-built metal floor can be removed.
