NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE. 3
These fi replace systems are designed for in-
stallation in accordance with the National Fire
Protection Standard for chimneys, fi replaces
and solid fuel burning appliances; NFPA 211-
latest edition and in accordance with codes
such as the BOCA Basic/National Codes, the
Standard Mechanical Code and the Uniform
Building Codes.
Note: These fi replace systems are not diffi cult
to install. However, in the interest of safety, it is
recommended that the installer be a qualifi ed or
certifi ed “tradesman” familiar with commonly
accepted fi replace installation and safety tech-
niques as well as prevailing local codes.
INTRODUCTION
General Information
These fi replaces are traditional radiant heat
fi replaces with standard bar grates, optional
Outside Air Kits (required for outdoor installa-
tions) and optional Operable Bi-Fold Stainless
Outdoor Glass Doors and Weather Cover.
These appliances are approved for installation
indoors or outdoors.
Indoors: These appliances are approved
for installation in residential homes and
other buildings of conventional construction
including commercial, not in manufactured
homes(see Figure 5).
Outdoors: These appliances are approved for
installion against an outside wall of a house,
or as a freestanding fi replace on the porch,
patio, or located in the yard (see Figure 6).
The Outdoor Fireplace must be enclosed to
prevent impact damage to the outside of the
fi replace. Build an outside enclosure out of
standard building materials, being careful to
maintain the minimum air clearances speci-
fi ed in these Installation Instructions. When
installing the fi replace as a freestanding unit
on your porch, patio or backyard, it must also
be enclosed to prevent impact damage to the
fi replace. However, the enclosure must now
be fi nished on all four (4) sides. The exterior
of the enclosure may be fi nished in a textured
plywood, a wood clapboard siding, brick, or
a cultured stone.
