Fireplace Size Requirements
A. Minimum Fireplace Opening
Minimum fireplace opening requirements are shown in
Figure 4.2.
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 appliance may not be placed directly on the base
of the outer wrap, a 1/4 in. airspace
MUST
be provided
between the insert and the floor of the outer wrap. Use
the levelling legs to raise the insert a minimum of 1/4
in.. 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.

• The metal floor of the factory-built fireplace 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 4.1-B.
• A minimum 1/2 in. gap from the bottom of the
appliance to the metal floor of the
factory-built
firebox
is
RECOMMENDED
for optimal fan performance. See
side view in Figure 4.1-A.
• If the recommended 1/2 in. leveling leg height can not be
achieved, a section of the factory-built metal floor may
be removed. See Figure 4.1-B and see Section 10.A for
clearance under appliance.
Note:
The metal warning plate, noting that the factory-built
fireplace has been converted for use with a gas fireplace
insert,
must be affixed to the appliance. It is
included in
the manual bag assembly.
