Site Selection
Review and consider all of the follow-
ing conditions before installation:
• Dimensions of the unit: 34.1 in.
(867 mm) x 19.4 in. (494 mm)
• For surface installation, the unit re-
quires a minimum of 2 wall studs in
order to ensure secure installation.
For other installation methods,
suitable framing is required.
There are three possible mounting
methods:
• Surface mount (pg. 10);
• Partial Recessed (pg. 11);
• Flush mount (pg. 12),
and any of these have the option of
being hard-wired or plugged directly
into the wall outlet.
WARNING: The top of the re-
place is to be installed at least 4"
(10.2 cm) from the ceiling.
CAUTION: Ensure installation
does not allow replace to be in
direct contact with building vapor
barrier or insulation and meets all
local building code.
!NOTE 1: A 15 Amp, 120 Volt
circuit is required. A dedicated
circuit is preferred but not essen-
tial in all cases. A dedicated circuit
will be required if, after installa-
tion, the circuit breaker trips or
fuse blows on a regular basis
when the heater is operating. Ad-
ditional appliances on the same
circuit may exceed the current
Fireplace Installation
rating of the circuit breaker.
WARNING: Ensure the power cord
is not installed so that it is pinched
or against a sharp edge and en-
sure that the power cord is stored
or secured to avoid tripping or
snagging to reduce the risk of re,
electric shock or injury to persons.
Construction and electrical outlet
wiring must comply with local
building codes and other applica-
ble regulations to reduce the risk
of re, electric shock and injury to
persons.
WARNING: To reduce the risk of
re, do not store or use gasoline
or other ammable vapors or
liquids in the vicinity of the heater.
1. Select a location that is not sus-
ceptible to moisture and is away
from drapes, furniture and high
tra󰀩c.
2. For ease of electrical hook up you
may wish to locate the replace
near an existing outlet (for plug-in
convenience) (refer to NOTE 1).
3. Remove replace, front glass
and hardware from the box and
remove all packaging materials
before installation.
4. Store the replace in a safe, dry
and dust free location until you
are ready to install the replace.

Grounding Instructions
This product must be grounded. If it
should malfunction or breakdown,
grounding provides a path of least re-
sistance for electric current to reduce
the risk of electric shock. This product
is equipped with a cord having an
equipment-grounding conductor and
a grounding plug. The plug must be
plugged into an appropriate outlet
that is properly installed and ground-
ed in accordance with all local codes
and ordinances.
DANGER: Improper connection of
the equipment-grounding conduc-
tor can result in a risk of electric
shock. Check with a qualied
electrician or serviceman if you
are in doubt as to whether the
product is properly grounded.
Do not modify the plug provided
with the product – if it will not t
the outlet, have a proper outlet
installed by a qualied electrician.
This product is for use on a nominal

Hardwire Installation
The replace is provided with a three
prong plug installed for plug-in con-
venience. Hard wiring the replace is
also an option for any installation.
WARNING: Do not attempt to wire
your own new outlets or circuits. To
reduce the risk of re, electric shock
or injury to persons, always use a
licensed electrician.
WARNING: Ensure that the circuit
on which the replace is to be
installed has the power cut o󰀨 at
the service panel until installation
is complete.
1. Carefully remove the electrical
cord bracket from the back of the
replace by removing the three
retaining screws. (Figure 3)
2. Remove the two wire access
covers o󰀨 of the unit at the front
to access the wire connections.
(Figure 4)
3. Pull the wires and connectors out
of the back opening.
4. Unscrew the three wire connec-
tors inside the electrical box and
separate the wires.
5. Install the supplied hardwire
bracket (with the ½" wire hole)
onto the rebox. (Figure 3)
6. Leaving a minimum of 3 in. (7.6
cm) of slack, route the power
supply wires through the hole in
the electrical cover bracket and
secure with a wire clamp (not

CAUTION: Two people may be
required for various steps of this
procedure.
1. Choose your method of supplying
power to the unit:
• Plug in to an existing outlet or
install an outlet nearby.
• Hard wire the replace. Follow the
hard wiring instructions on page 8.
WARNING: Do not attempt to wire
your own new outlets or circuits. To

or injury to persons, always use a
licensed electrician.
WARNING: Ensure that the circuit
on which the replace is to be
installed has the power cut o󰀨 at
the service panel until installation
is complete.
2. Determine the mounting location
of the unit so that the wall mount-
ing bracket can be installed into 2
wall studs.
!NOTE: It is recommended that
the mounting bracket be installed
56 in. (142 cm) o󰀨 of the ground
to maintain an optimized viewing
angle of the ame.
3. Hold the wall mounting bracket,
with the bubble level on the top,
on the wall so that the bubble on
the level is centered between the
two black lines.
8. Connect the blue and white wires
(N) from the unit to the neutral
wire from the power supply using
the second wire connector from
step 4.
9. Connect the green wire (G) from
the unit to the ground wire from
the power supply using the third
wire connector from step 4.
10. Reposition the wire access covers
over the wires and connectors
and attach to replace chassis us-
ing the screws removed in step 2.
11. Refer to Front Glass Installa-
tion section for nal installation
procedures.
