PRECAUTIONS
Note: These fireplace systems are not difficult
to install. However, in the interest of safety, it is
recommended that the installer be a qualified or
certified “tradesman” familiar with commonly
accepted fireplace installation and safety tech-
niques as well as prevailing local codes.
The most important areas of concern dealing
with the installation of factory-built fireplaces
are clearances to combustible materials, proper
assembly of component parts, height of the
chimney system, the proper use of accessories
supplied by the manufacturer and the tech-
niques employed in using finishing materials
applied to the wall surrounding the fireplace,
hearth extensions and wall shields. Each of
these topics will be covered in thorough detail
throughout this manual. Please give each your
special attention as you progress with your
installation.
INTRODUCTION
General Information
The LBR Series fireplace is a traditional wood
burning radiant heat system. The LBC Series
fireplace is a traditional wood burning heat
circulating system. These fireplaces come with
standard bar grates, optional outside combus-
tion air kits and optional decorative glass doors.
Note: Illustrations shown reflect “typical” instal-
lations with nominal dimensions and are for
design and framing reference only. Actual instal-
lations may vary due to individual design prefer-
ences. However, always maintain minimum clear-
ances to combustible materials and do not vio-
late any specific installation requirements.
These fireplaces have been tested and listed by
Warnock Hersey (Report No. 629-915173A)
to U.L. standard 127 for US and ULC S610 for
Canada. These units are intended for installa-
tion in residential homes and other buildings
of conventional construction including com-
mercial, not in mobile homes.
These fireplace systems are designed for in-
stallation in accordance with the National Fire
Protection Standard for chimneys, fireplaces
and solid fuel burning appliances; NFPA 211
and in accordance with codes such as the
BOCA Basic/National Codes, the Standard Me-
chanical Code and the Uniform Building Codes.
CLEARANCES AND HEIGHT
REQUIREMENTS
The fireplace may be placed on or near normal
construction materials*. The combustion air
kit, firestop spacer and roof flashing (not chase
flashings) may be placed directly on or against
normal construction materials.* The chimney
requires a minimum 2" air space to combus-
tibles and the fireplace outer wrapper requires
a minimum 1/2" air space to combustibles. A
combustible mantle may be installed 12" above
the opening of the fireplace as per NFPA 211,
Section 7-2.3.3. In Canada, the minimum is
18" (441mm) above the fireplace opening.
The minimum installed height of the completed
fireplace system is 14' 0". The maximum height
is 80' 0".
The fireplace and chimney system must be
enclosed when installed in or passing through
a living area where combustibles or people may
come in contact with it. This is important to
prevent possible personal injury or fire hazard.
For questions, please call your distributor or
the manufacturer. Special restrictions apply to
the front and facing of the fireplace and nearby
walls (See pages 16 and 17 ).
