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 com-
monly accepted fireplace installation and safety
techniques 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 techniques
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 at-
tention as you progress with your installation.
IMPORTANT NOTES:
• WHEN INSTALLING IN CANADA (EST-36
AND EST-42 ONLY), THE COLD CLIMATE KIT
MUST BE INSTALLED PER THE WARNOCK
HERSEY LISTING (see Step 6 on page 12
and “Installation Components” on page 24.
• THE MINIMUM AIR SPACE TO COMBUS-
TIBLES FOR THE CHIMNEY SYSTEM IS 2"
(51mm).
• THE FTF13 CHIMNEY SYSTEM IS NOT FOR
USE IN CANADA. MODEL EST-50 IS NOT
FOR USE IN CANADA.
INTRODUCTION
General Information
These fireplaces are conventional radiant heat
fireplaces with standard bar grates, optional
outside combustion air kits and optional decora-
tive glass doors.
Note: Illustrations reflect “typical” installations
with nominal dimensions and are for design
and framing reference only. Actual installations
may vary due to individual design preferences.
However, always maintain minimum clearances
to combustible materials and do not violate any
specific installation requirements.
Models EST-36 and EST-42 have been tested
and listed to U.L. 127 standard for U.S. instal-
lations and U.L.C. S610 standard for Canadian
installations by Warnock Hersey Inc. (Report
No. J20054576-231). Model EST-50 has been
tested and listed to U.L. 127 standard for U.S.
installations by PFS-US (Report No. 09-185)
for EST-50.
These units are intended for installation in
residential homes and buildings of conventional
construction, 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, Uniform Building Codes and/or the
Canadian National Code.
CLEARANCES AND HEIGHT
REQUIREMENTS
The fireplace may be placed on or near normal
construction materials.* The combustion air kit,
firestop spacer and roof flashings (not chase
flashings) may be placed directly on or against
normal construction materials.* The chimney
requires a minimum 2" (51 mm) air space to
combustibles. A combustible mantel may be
installed a minimum of 12" (305 mm) above
the opening of the replace as per NFPA 211,
“Mantel/Trim Clearances” Section. In Canada the
minimum is 24" (610 mm) above the opening.
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 20 and 21).
