• Locating Your Fireplace
This electric fireplace can be installed in a mantel, framed into a wall or installed
into an existing fireplace. If installing into a mantel, follow mantel's assembly instruc-
tions. Figure 3 illustrates a variety of ways the heater may be located in a room. The
heater may be installed directly on the floor or raised on a hearth.
• Unpacking and Testing
WEF33
Carefully remove unit from box. Prior to permanently installing unit, test to make sure
unit operates properly. To do this, plug unit's power cord into a conveniently located
10 Volt grounded outlet.
WEF36
Carefully remove unit from box. Prior to permanently installing unit, test to make sure
unit operates properly. Unit does not come with the power cord installed. Unit must
be hard-wired to either a 10/60 or 40/60 volt supply.
CAUTION: The unit's
power supply cord
must be connected to
a properly grounded and pro-
tected 10 Volt outlet. Always
use ground fault protection
where required by the electri-
cal code.
WARNING: Do not
operate the unit if it is
damaged or has mal-
functioned. If you suspect the
unit is damaged, return the unit
to an authorized service facil-
ity for examination, electrical
or mechanical adjustment or
repair.
WARNING: Due to
high temperatures,
this heater should
be located out of trafc. Keep
combustible materials such as
furniture, pillows, bedding, pa-
pers, clothes and curtains at
least 3 feet (914 mm) from the
front of the heater.
WARNING: Never
locate this heater
where it may fall into
a bathtub or other water con-
tainer.
NOTICE: Minimum and maxi-
mum clearances must be main-
tained at all times. Illustrations
throughout these instructions
reect typical installation and
are for design purposes only.
Actual installations may vary
slightly due to individual pref-
erences.
WARNING: To pre-
vent contact with sag-
ging or loose insula-
tion, the heater must
not be installed against vapor
barrier or exposed insulation.
Localized overheating could
occur and a re could result.
CAUTION: Do not
expose the heater to
the elements (such
as rain, etc.)
CAUTION: Wear
gloves and safety
glasses for protection
during installation and maint-
neance.

• Install Fireplace
Select a suitable location that is not susceptible to moisture and is a safe distance
from drapes, furniture and high traffic areas.
NOTE: Follow all national and local electrical codes. This insert can be installed into
either an existing fireplace or as a new construction/renovation.
• Installing in a Mantel
1. Assemble mantel according to mantel instructions.
. Locate mantel near a wall (or corner depending on mantel type) close to a power
source. You may have to alter base boards to fit mantel flush against wall.
3. Insert fireplace into front of mantel. Be careful not to scratch finish on base.
Fireplace will fit flush against front of mantel.
4. Plug fireplace into power source. Push mantel with fireplace into final location.
NOTE: The MHSC Barrington Cabinet Mantel Model series BWC300, BWC400 and
BWC500 are specially designed to comply with all mantel temperature requirements.
Any custom-built mantel must comply with all clearance requirements shown in this
instruction manual.
• Existing Fireplace Installation
1. Thoroughly clean out existing fireplace and hearth area.
. Seal all drafts, vents or ash clean-outs with fiberglass insulation. Seal flue. Once
sealed, close damper to stop debris from falling onto unit.
3. If existing firebox is susceptible to moisture, cap top of chimney flue to prevent
infiltration of water.
NOTE: It is strongly advised that you hire a qualified professional to undertake this
step in order to prevent personal injury. Once flue is capped, chimney is no longer
suitable for wood burning.
NOTE: Do no install this unit into a fireplace that is prone to dampness; the area of
installation must be dry.
4. Plan the power supply. If an existing grounded outlet is near fireplace, power
cord can run along front of fireplace. If cord is not long enough to reach outlet,
a grounded extension cord minimum 14 AWG and rated to a minimum of 1875
watts, may be used. If you plan to cut or drill a hole in existing fireplace for wir-
ing, it is best to hire a professional to do this step in order to prevent personal
injury. To reduce the risk of fire, do not run power cord under rugs, carpets, etc.
Arrange power supply cord away from high traffic areas where it may pose a trip-
ping hazard.
• New Construction or Renovation
1. Select a location away from combustible materials such as curtains or drapes,
furniture, bedding, paper, etc.
. Mark desired location on floor and store unit in a safe, dry and dust free location.
3. Frame in an opening leaving at least 1/4" (6 mm) around the edge of the unit
(refer to Framing). Any new wiring must be done in compliance with local and
national codes and other applicable regulations in order to reduce the risk of fire,
electric shock or other injuries. Therefore, it is strongly recommended that you
hire a professional to complete any such work.
4. Plan your power supply route. Refer to Step 4 Existing Fireplace Installation.
WARNING - RISK
OF FIRE! The pow-
er cord must not be
pinched or against a sharp
edge. Secure cord to avoid
tripping or snagging to reduce
the risk of re, electric shock
or personal injury.
— Do not run cord under car-
peting. Do not cover cord with
throw rugs, runners or the
like. Arrange cord away from
trafc areas and where it will
not be tripped over.
WARNING - RISK
OF FIRE! To prevent
a possible re, do
not block air intake or exhaust
in any manner. Do not use on
soft surfaces where openings
may become blocked.
WARNING - RISK
OF FIRE! Do not
blow or place insu-
lation against the rebox.
WARNING: If the
information in these
instructions is not
followed exactly, a re or ex-
plosion may result causing
property damage, personal
injury or death.
— Do not store or use gaso-
line or other ammable va-
pors in the vicinity of this or
any other heater.
WARNING: The sol-
id fuel/gas replace
has been converted
for use with an electric insert
and cannot be used for origi-
nal fuels unless all original
parts have been replaced and
the replace has been reap-
proved by the authority hav-
ing jurisdiction.

• Framing
Figure 4 shows a typical framing of the heater using combustible materials. All
required clearances to combustibles must be adhered to. Header height is measured
from the base of the heater.
Tools and building supplies required for installation:
• Saw • Square
• Pliers • Gloves
• Hammer • Level
• Philips screwdriver • Surround
• Framing materials • Electric drill/bits
• Tape measure
• Wall-finishing materials
• Caulking material

Figure 4
NOTE: The height that a com-
bustible mantel is tted above the
heater is dependent on the height
of the front selected. The minimum
height is 1" above the front.
CAUTION: Provide
adequate clear-
ances around the
air openings and adequate
accessibility clearances for
servicing and proper opera-
tions.
• Nailing Flange Installation
1. The replace has an adjustable nailing ange that will accommodate wall
installations from 1/" to 1Z\x" thick.
. Secure the nailing ange to the framing member. It is recommended to
remove the front face of the replace when nailing the ange to the wall.
Refer to the cleaning and maintenance section.
3. The nailing ange can be adjusted front to back by loosening the screw
that secures the nailing ange to the replace. Do not remove the screw
completely.

• Finishing
Combustible Finishing Material - Materials made of or surfaced with wood, com-
pressed paper, plant fibers, plastics or any material capable of igniting and burning,
whether flame proofed or not, plastered or unplastered (this includes drywall).
Noncombustible Finishing Material - Materials which will not ignite and burn. Such
materials are those consisting entirely of steel, iron, brick, tile, concrete, slate, glass
or plasters or combinations thereof or have a fire rating of zero.
• Finishing Checklist
Power supply service must be completed prior to finishing to avoid reconstruction.
Grilles and air openings cannot be covered under any circumstances.
NOTE: The heater is a zero clearance fireplace and may be finished with combus-
tible or noncombustible finishing materials.
When using paint or lacquer to finish the mantel, they must be heat resistant to pre-
vent discoloration.
WARNING: Con-
trol panel door on
this heater cannot,
in any way, be covered as it
may create a re hazard.

ging into a 15 amp/10 volt, grounded outlet.
3. Push fireplace insert so trim is against finished mantel or wall surface.
• WEF36 - 240V AC Installation
1. Loosen the screw securing the junction box cover and remove cover.
