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.
INTRODUCTION
General Information
The CST-38 and CPF-38 Series are radiant-
heat, two-sided and three-sided fireplaces with
required glass doors, that must be ordered
separately. A steel grate is included with the
CST-38 and CPF-38 to properly position the
fire. An outside combustion air kit is available
as optional equipment.
TYPICAL INSTALLATION
Model CST-38
Figure 1
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 Labs (Report No. 116-F-20-4) to
U.L. standard 127. These units are intended for
installation in residential homes and other build-
ings 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.
WARNING: FAILURE TO USE MANUFAC-
TURE PROVIDED PARTS, VARIATIONS IN
TECHNIQUES AND CONSTRUCTION MA-
TERIALS OR PRACTICES OTHER THAN
THOSE DESCRIBED IN THIS MANUAL
MAY CREATE A FIRE HAZARD AND VOID
THE LIMITED WARRANTY.
Chimney and
Termination
Model CPF-38
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
The CST and CPF systems consists of four
"subsystems":
1. The Fireplace and Door Assemblies
2. The Chimney and Termination
3. The Optional Combustion Air Kit
4. The Chimney Air Kit (Canada Only)
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 CPF-38 fireplace opening must be kept a
minimum of 8" (203 mm) from an unprotected
combustible side wall. The CST-38 fireplace
opening must be kept a minimum of 8"
(203 mm) from a protected combustible side
wall. A perpendicular side wall can not be
closer that 7" (178 mm) for both the CPF-38
and CST-38 fireplaces. If there is a continuous
perpendicular side wall closer than 18" from
the CST-38 fireplace opening, it must be pro-
tected with a 40" x 40" x
1016 mm x 13 mm) wall shield constructed of
millboard or a durable noncombustible mate-
rial with an equal or greater insulating value
than k=.84 BTU IN/FT
2
HR F (refer to page 18).
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.
