vide greater clearances from

Minimum Wall and Ceiling
Clearances (see Figure 21)
A. Clearances from the side of the fire-
place opening to any combustible wall
should not be less than 16 inches for a
cabinet mantel or 12 inches for a cor-
ner installation.
B. Clearances from the top of the fireplace
opening to the ceiling should not be less
than 42 inches.
Note:
The instructions below show installa-
tion using the GMC11F/GMC12U/
GCM13F series cabinet mantel and the
GC3333F/GC3334U/GC3335F series
hearth base accessories (see Accessories,
page 25). A brass trim kit is included with
each mantel accessory. The hearth base ac-
cessory shown is optional for this installa-
tion. You can install fireplace and cabinet
mantel directly on the floor.
1. Assemble cabinet mantel, brass trim
kit, and hearth base. Assembly instruc-
tions are included with each accessory.
2. If installing an optional blower acces-
sory (see Accessories, page 25). Install
a properly grounded 120 volt, three
prong electrical outlet at fireplace lo-
cation if outlet is not there. If possible,
locate outlet so cabinet mantel will
cover it when installed (see Figure 23).
3. Break off nailing flanges (see Figure
22) with hammer or pliers.
WARNING: For conventional
installation, it is recommended
you use the cabinet mantel or
hearth bases specified in this
manual. Surface clearances may
not be sufficient with other cabi-
net mantels and hearth bases.
This may create a fire hazard. See
Accessories
, page 25, for correct
mantels and hearth bases.
