WARNING
When using a gas burner, it is
mandatory to keep the chimney
outside air register opened.
Preinstallation
Please Read Before Installing:
1. Before beginning the installation of your
fireplace, read these safety tips and instal-
lation instructions carefully to be sure you
understand them completely. Failure to
follow them could cause a fireplace malfunc-
tion resulting in serious bodily injury and/or
property damage.
2. The HE43-2 fireplace has been tested and
listed to UL and ULC standards by Warnock
Hersey International Inc. These instructions
were written to give you an outline for a fast
and safe installation and reliable operation.
Failure to use Security Chimneys International
parts or conduct variations in techniques
and construction materials described in this
installation manual may create a serious fire
hazard and may void the warranty and the
WHI listing.
3.
Always check your local building codes.
The installation must comply with their
regulations. Before beginning the instal-
lation, consult the local authorities and
make sure your building permit complies
with their requirements.
4. This fireplace must be installed with Security
Chimneys™ chimney system models ASHT+,
S-2100+ or AC, of 8" inside diameter. The
chimney system must always vent to the
outside of the building.
5. To maintain top efficiency and to prevent
build-up of soot and creosote, inspect and
clean the chimney periodically during the
heating season.
6. To prevent possible hazards due to poor
combustion and to avoid affecting other fuel
burning appliances (furnace, wood stove,
etc.), ensure that the outside air kit is properly
installed.
7. This fireplace is designed to allow the instal-
lation of a gas burner. In such a case, the
installation must conform with the National
Gas Code ANSI Z223.1 and Z21.60.

PRECAUTIONS!
The most important areas of concern dealing
with the fireplace installation are clearances
to combustible materials, secure assembly of
components parts, the height of the chimney
system, the proper use of accessory equip-
ment and the techniques used in using finish-
ing materials applied to fireplace surrounds,
hearth extensions and wall coverings. Each
of these topics will be covered in greater detail
throughout this manual.
Please give special
attention to these instructions as you progress
with your installation.
Fireplace Installation Procedure
1. Move the fireplace into the desired position
(follow the recommendations below for
enclosure).
2. Install the outside air assembly (or assem-
blies) - refer to
Page 13
.
3. Install the enclosure surrounding the fireplace
(see
Pages 9 through 12
).
4. Install the hearth extension (see
Page 10
).
Make sure the gap between the fireplace and
the hearth extension is sealed.
LOCATING THE FIREPLACE
Do not place the fireplace on carpeting, vinyl or
other soft surface floor coverings. It may, how-
ever, be directly placed on flat wood, plywood,
particle board or other hard surface materials.
8. This fireplace has provision for the installa-
tion of a gas pipe and is intended only for
connection to a decorative gas appliance
incorporating an automatic shutoff device
and complying with ANSI Z21.60-M96/CGA
2.26-M96, Standard for Decorative Gas Ap-
pliances for Installation in Solid-Fuel Burning
Fireplaces (reference Clause 4.1.3 T).
9. The HE43-2 fireplaces are sold with factory
installed doors.
The outside combustion
air kit is mandatory
and is included with the
fireplace. Optional blowers and decorative
trims are available.
ADJACENT WALL
A wall perpendicular to and in front of the fire-
place front facing must be at least 18" (460mm)
from the fireplace opening. A wall at 45º to the
front facing and starting at the fireplace’s outer
edge is permitted. Projections within this area
are permitted. See
Figure 7
.

ENCLOSURE
1.
WARNING:
Do not place loose insulation or
any other material in the space around the
fireplace or the chimney. Insulation placed
on or around the fireplace or chimney may
cause adjacent wood to overheat and catch
on fire.
2. The fireplace must be installed against a
finished wall (like drywall finish). It must
not be installed against a vapor barrier or
exposed insulation (see
Figure 10
).
3. The fireplace is zero clearance. Combustible
materials like wood, plywood, particle board
or drywall can be in direct contact with the
fireplace reinforcements.
Two inch (50 mm)
clearance to combustibles must be kept
around the chimney.
4.
WARNING
: The top of the fireplace is not
zero clearance. Do not place any insulating
material in the space above the fireplace for a
height of 7 feet from the base of the fireplace.
5. Do not block the fireplace’s hot air vents or
air inlets as this will cause the fireplace to
overheat.
CHASE ENCLOSURE
A chase is a vertical box-like structure construct-
ed to surround the fireplace and chimney. Refer
to
Figure 10
for a typical chase configuration.
A chase should be constructed and insulated
just like any outside wall. In a cold climate,
we recommend the base of the chase should
also be insulated between the solid continuous
base beneath the fireplace and the outside base.
Chase insulation in a cold climate installation
is not required for safety.
