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 as-
sembly of component parts, height of the chim-
ney system, the proper use of accessories sup-
plied by the manufacturer and the techniques
employed in using finishing materials applied to
the wall surrounding the fireplace, hearth exten-
sions 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.
TYPICAL INSTALLATION
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
and fireplace outer wrapper require a mini-
mum 2" and 1" air space to combustibles
respectively. A combustible mantle may be
installed 12" above the opening of the fireplace
as per NFPA 211, Section 7-2.3.3.
The fireplace opening of the LS43ST must be
kept a minimum of 12" (305 mm) from a side
wall. A perpendicular side wall can not be
closer that 12" (305 mm) to the LS43ST
fireplace.
As with all chimney installations, avoid over-
head obstructions such as trees, power lines,
etc. Additionally chimney terminations must
meet certain clearance to roof requirements
detailed in the paragraph titled Ten-Foot Rule
Summary.
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 18, 19 and 20 ).
INTRODUCTION
General Information
This Signature Series LS43ST is a radiant-
heat, two-sided fireplace with a variety of
glass door options. A steel grate is also in-
cluded with the LS43ST to properly position
the fire. An outside combustion air kit is
available as optional equipment.
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 Omni-Test Laboratories (Report No. 116-
F-19-02) to U.L. standard 127. These units
are intended for installation in residential
homes and other buildings of conventional
construction including commercial, 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 Mechani-
cal Code and the Uniform Building Codes.
The local authority having jurisdiction should
be consulted before installation, to determine if
any permits need to be obtained.
The LS43ST system consists of three “sub-
systems”:
1. The Fireplace and Door Assemblies
2. The Chimney and Termination
3. The Optional Combustion Air Kit
