INTRODUCTION

Model 368ST series is a wood burning fireplace intended and
approved for installation in either residential homes or buildings
of standard construction.

This model fireplace is not for use in mobile homes.

This fireplace system requires the utilization of an FMI 8”
double wall, snap-lock flue pipe system.

BE SURE TO CHECK WITH YOUR LOCAL BUILDING
CODES FOR AREA REQUIREMENTS BEFORE
INSTALLING THIS FIREPLACE.

The model’s serial number and any other specific rating
information may be found on the unit in the WARNOCK
HERSEY RATING PLATE located at the interior of the
fireplace’s opening.

BEFORE YOU BEGIN:
Before beginning the installation of your fireplace read these
instructions through completely. This FMI fireplace and its
approved components are safe when installed according to this
installation manual and operated as recommended by FMI.
Unless you use FMI approved components tested for this
fireplace, YOU MAY CAUSE A FIRE HAZARD.

The FMI warranty will be voided by, and FMI disclaims any
responsibility for the following actions:

A) Modification of the fireplace, doors, blowers, fans, air inlet

system or damper control.
B) Use of any component part not manufactured or approved
by FMI in combination with an FMI fireplace system.

PROPER INSTALLATION is the most important step in
ensuring safe and continuous operation of this fireplace.
Consult the local building codes as to the particular
requirements concerned with the installation of all factory built
fireplaces. Although grounding may not be required by code,
the manufacturer recommends it.

CAUTION: THE STRUCTURAL INTEGRITY OF THE MOBILE
HOME FLOOR, WALL AND CEILING/ROOF MUST BE
MAINTAINED.

WARNING: DO NOT INSTALL A FIREPLACE
INSERT IN THIS FIREBOX UNLESS THE
MANUFACTURER’S INSTRUCTIONS WITH THE
INSERT SPECIFICALLY STATE THIS FIREBOX HAS
BEEN TESTED FOR USE WITH THE INSERT.

This wood burning fireplace complies with UL 127 as a
FACTORY BUILT FIREPLACE.

NOTE:

A qualified installer familiar with fireplaces should do
installation and repair. The fireplace and chimney system
should be inspected and cleaned before use, and periodically

thereafter especially during heating season to prevent the
excessive build-up of soot and creosote and to ensure a safe
operating system.

THIS FIREPLACE IS NOT INTENDED TO BE USED AS A
PRIMARY SOURCE OF HEAT. USE FOR SUPPLEMENTAL
HEAT ONLY.

SELECTING LOCATION

To determine the safest and most efficient location for your
fireplace, you must take into consideration the following
guidelines:

1. The location must allow for all the proper clearances, (See
Figure 2).

2. Consider a location where the heat output would not be
affected by drafts, air conditioning ducts, windows or doors.

3. A location that avoids the cutting of joists or roof rafters will
make installation easier.

4. An outside air kit is included with this fireplace. Accessibility
to outside combustion air must be considered. This can also
be achieved through a vented crawl space in some cases, for
more details refer to section on outside air kit installation.

FIGURE 2 shows a plan view of common locations.

Figure 2

The typical installation for a 368ST is a projected installation,
which allows you to extend the fireplace any distance into the
room. A projection may be ideal for a new addition on an
existing finished wall.

IN SELECTING A LOCATION, THE FOLLOWING

g

PRECAUTIONS MUST BE OBSERVED:

1. Do not connect this fireplace to a chimney system other than
an FMI chimney system.

2. Install in an area providing ventilation and adequate
combustion air.

3. Due to high temperatures, do not locate this fireplace in high
traffic areas or near furniture and draperies.

4. Provide adequate clearances around air openings into the
combustion chamber. NEVER obstruct the front opening of the
fireplace or the flow of combustion and ventilation air.

5. Do not locate in or near an area where gasoline or other
flammable liquids may be stored. The fireplace area must be
kept clear and free from combustible material.

CLEARANCES

MINIMUM CLEARANCES TO COMBUSTIBLE ARE:

BACK:...................................................1” MIN.

PERPENDICULAR SIDE WALL:..................12” MIN.

CHIMNEY OUTER PIPE SURFACES:............2” MIN.

BOTTOM OF FIREPLACE TO FLOOR:...........0” MIN.

(See step 2 under Installing the Fireplace section)

CAUTION:

INSULATION OR ANY OTHER MATERIAL. DO NOT
OBSTRUCT EFFECTIVE OPENING OF FIREPLACE WITH
ANY TYPE OF FACING MATERIAL. COMBUSTIBLE
MATERIAL MUST NOT BE IN CONTACT WITH THE FRONT
FACE OF THE FIREPLACE.

MANTEL CLEARANCES

Woodwork, such as wood trims, mantels, and other
combustible materials, should not be placed within 9 inches of
the effective opening of this fireplace

DO NOT BLOCK REQUIRED AIR SPACES WITH

. The effective
opening is considered the opening where actual heat
output may occur.
Combustible material above and projecting more than 1­1/2 inches from the fireplace front face, (see figure 4),
should not be placed less than 12 inches from the
effective opening of the fireplace (ref; NFPA std. 7-

3.3.3).

Fi

Mantels or any other combustible material also may come up to
the side periphery of the black metal face to the fireplace, just
as long as the projection from the front face falls within the

Figure 5

limits shown in Figure 5.

INSTALLING THE FIREPLACE

STEP 1: Construct framing using dimensions shown in figure
6,8, and 9, depending on your particular installation.
STEP 2: If the fireplace is to be installed directly on carpeting,
tile (other than ceramic), or any combustible material other
than wood flooring; the fireplace must be installed upon a metal
or wood panel extending the full width and depth of the
fireplace.
STEP 3: Set the fireplace directly in front of this opening and
slide the unit back until the mounting flanges touch the side
framing.
STEP 4: Check the level of the fireplace and shim with sheet
metal if necessary.
STEP 5: Before securing fireplace to prepared framing, the
ember protector, (provided), must be placed between hearth
extensions, (not supplied), and bottom front edge of the
fireplace to protect against glowing embers (see Figure 7). If
the fireplace is to be installed on a raised platform, a “Z-type”
ember protector, (not supplied), must be fabricated to fit your
required platform height, (see Figure 8). The ember protector
is made of (26-28ga) galvanized sheet metal to prevent
collision.
STEP 6: Secure the fireplace to the framing through the
flanges located on the sides on the fireplace with 8-penny nails.

HEARTH
EXTENSIONS

A hearth extension is required to protect combustible floor
surrounding the fireplace. You may obtain kit No. HE-368ST
(see accessories on page 13) or you may fabricated your own
per the dimensions shown on Figure 6.

The hearth extension must project 16 inches minimum to the
front and 8 inches minimum beyond each side of the fireplace
opening, (See Figure 6).

If a hearth extension is to be field constructed, it must be made
of non-combustible, inorganic material having an effective
thermal conductivity “K” of 0.84 BTU In/Ft2 Hr.F or less at 1.0
inch thickness.
Thermal conductivity “K” of materials can be obtained from the
manufacturer.
The minimum required thickness for any material could be
obtained from the manufacturer or supplier of the non­combustible material. For example, if the material selected has
a “K” factor of 0.25 such as glass fiber, the following formula
would apply:

0.25

0.84

x 1.0 inch = 0.30 Thickness required
