The LSO-43 fireplace is a traditional wood
burning radiant heat system. The LSO-43-H
comes with Herringbone styled refractory.
These fireplaces come with standard bar grates,
air inlet and optional decorative glass doors.
The fireplace is intended to be installed outside
of the home. It could be installed against the
outside wall of the house, or as a freestanding
fireplace on the porch, patio, or simply located
in the yard (
see Figure 2
).
lations may vary due to individual design preferences. However, always maintain minimum clearances to combustible materials and do not violate any specific installation requirements.
These fireplaces have been tested and listed by
Omni Laboratories (Report No. 116-F-01-2) to
U.L. standard 127 for US and ULC S610 for
Canada. These units are intended for installation outside of a residential building only.
WARNING: DO NOT PACK OR FILL RE-
The Outdoor Fireplace must be enclosed. To
prevent impact damage to the outside of the
fireplace. Build an outside enclosure out of
standard building materials, being careful to
maintain the minimum air clearances specified
in these Installation Instructions.
When installing the fireplace as a freestanding
unit on your porch, patio or backyard, it must
also be enclosed to prevent impact damage to
the fireplace. However, the enclosure must
now be finished on all four (4) sides. The
exterior of the enclosure may be finished in a
textured plywood, a wood clapboard siding,
brick, or a cultured stone. Vinyl siding is not
recommended for use on the front of the
fireplace due to the heat the unit produces.
This can cause the vinyl siding to deteriorate.
QUIRED AIR SPACES WITH INSULATION
OR OTHER MATERIAL. NO MATERIAL IS
ALLOWED IN THESE AREAS.
WARNING: IF INSULATION IS USED,
THE FIREPLACE MUST NOT BE PLACED

LOCATION OF FIREPLACE
ASSEMBLY STEPS
These fireplaces are designed and code listed
for use with Security's FTF10 chimney System
only. Always use Security's FTF10 chimney
components with these fireplaces. Do not modify
or alter these components as this may cause a
potential serious hazard and void the Warranty.
Note: Do not insulate the chase cavity with
blown or fill type insulation materials.
Note: Local codes may not require firestops at
the ceiling levels for outside chase installations. However, it is recommended for safety
and the reduction of heat loss.
Chimney Height
The total height of your completed fireplace
system from the surface the fireplace rests
on to the chimney top must not exceed 80'
(24.4) and must also meet minimum height
requirements. Refer to the minimum system

).
ASSEMBLY OUTLINE
Before You Start
Check your inventory list to be sure you have all
the necessary parts supplied in good usable
condition. Check also for any concealed damage.
Carefully select the proper location for chimney
obstructions, clearance to side wall(s) air inlet
location and aesthetics. With proper pre-planning, a slight adjustment of a few inches can
save considerable time and expense later during construction and assembly. See
Figure 2
for some examples.

ure 1
) to get a general idea of each element of
Fig-
your fireplace system.
PRE-INSTALLATION NOTES
The fireplace may be installed directly on a
combustible floor or raised on a platform of an
appropriate height. Do not place the fireplace
on vinyl or other soft floor coverings. It may,
however, be placed on flat wood, plywood,
particle board or other hard surfaces.
Be sure the fireplace rests on a solid continuous floor or platform with appropriate framing
for support.
The fireplace may be positioned and then the
framing built around it, or the framing may be
constructed and the fireplace positioned into
the opening.
Usually, no special floor support is needed for
the fireplace, however, to be certain:
1. Estimate the total weight of the fireplace
system including chimney and surround materials such as brick, stone, etc., to be installed. Shipping weights for the fireplace may
be found on page 18.
2. Measure the square footage of the floor
space to be occupied by the system, surrounds
and hearth extensions.
4
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
3. Note the floor construction, i.e. 2 x 6’s, 2 x 8’s
or 2 x 10’s, single or double joists, type and
thickness of floor boards.
4. Use this information and consult your local
building code to determine if you need additional support.
If you plan to raise the fireplace and hearth
extension, build the platform assembly then
position fireplace and hearth extension on top.
Secure the platform to the floor to prevent
possible shifting.
WATERPROOFING THE FIREPLACE
Although the LSO-43 fireplace is designed to
drain to the front most of the water from rain
and other sources that may enter the hearth
area, condensation and unusual conditions
may cause water to collect inside the fireplace bottom.
To prevent this, the builder must provide a
means to drain water from under the fireplace by building or installing a water collector of the builder's choice, or installing a PVC
drain as follows:
Seal All
Seams,
Joints
And
Corners
Around The
Bottom Of
Fireplace
Drain Connector
(see Detail A )
Threaded
Reducer
³⁄₄” x ¹⁄₂”
(PVC)
Access
Drain Plug
Through
Air Inlet
Opening
Threaded
Elbow ³⁄₄”
@ 90°
(PVC)
Note: The LSO-43 has been provided with a
drain plug under the fireplace by the air inlet
opening. If the fireplace is on a platform or
wooden surface, a hole must be bored to make
room for an elbow connector. If the fireplace is
on a concrete floor, it will be necessary to
elevate the appliance at least 1" high to permit
the installation of an elbow connector.
Step 1. Seal all joints, gaps and corners around
the bottom of the fireplace before positioning
the fireplace on its location (
Figure 4
).
Step 2. Locate the drainage plug and remove
it by depressing the locking tabs and pushing
down through the outside air opening at the
bottom of the fireplace.
Step 3. On the exposed hole, install a PVC
threaded coupling reducer, 3/4" x 1/2" going
from inside of the fireplace out. Apply a
silicone-based sealant around the base and
threads before installation.
Step 4. Holding the reducer coupling with a
wrench, thread a 3/4", 90 degree, PVC elbow to
the reducer until it is tight to the metal.
Note: To assure proper drainage, the fireplace
must be installed on a leveled surface.
Air Inlet
The installation of the air inlet is required for
safe fireplace operation.
Step 1. Determine the location for air inlet,
which can be installed through an outside
wall. A 6 1/2" diameter hole will be required
for installation of the air inlet assembly (
Figure 17
).
CAUTION: AVOID INSTALLING THE AIR INLET WHERE THE OPENING COULD BE
BLOCKED BY SNOW, BUSHES OR OTHER
OBSTACLES. THE MAXIMUM HEIGHT FOR
THE OUTSIDE AIR IS 50 FEET ABOVE THE
HEARTH, PROVIDING THE AIR INLET IS TERMINATED A MINIMUM OF THREE (3) FEET
BELOW THE CHIMNEY CAP LEVEL.
Note: Air inlet ducts must not terminate in
attic space.
see
Note: Clearance at the nailing flange for both
fireplace models is 0" (0mm).
Note: Adjacent wall considerations are for an
adjacent wall on only a single side. Walls
should not be placed at minimum distance at
both sides of the fireplace.
INSTALLING THE FIREPLACE
Step 1. Slide the fireplace into prepared fram-
ing or position fireplace in its final position and
frame later.
The fireplace may not be recessed into a combustible floor. Maintain the floor to hearth
clearance established by the fireplace lower
front face.
Step 2. Insert the provided metal safety strips,
beneath the fireplace as illustrated (
and 7
). The safety strips should overlap ¹⁄₂"
min. for continual coverage of the floor.

Note: Install the hearth extension only as illus-
trated (see Figures 41 and 42 ).
The safety strips should extend from front of
the fireplace at least 1 ¹⁄₂" and should extend to
be at least flush with the sides. In the event a
wooden support is used to elevate the fireplace
above the floor, a “Z” type safety strip should be
fabricated and used to protect the front surface
of the wood support as well as the floor beneath
the hearth extension (
Figures 7 and 8
). The
safety strips should be tacked down to prevent
possible movement.
Note: The “Z” type safety strip is not supplied.
