Site Selection
Review and consider all of the fol-
lowing conditions for installation:
• Dimensions of the unit: 505/16"
(128cm) x 19½"(49.5cm)
• Unit requires a minimum of two
wall studs in order to ensure a
secure installation
There are three possible mount-
ing methods:
• Surface mount (pg. 11);
• In-wall Recessed (pg. 13);
• Flush mount (pg. 14),
and any of these have the option
of being hard-wired or plugged
directly into the wall outlet.
!NOTE:If the desired replace
location is on the interior of an ex-
terior wall the unit should only be
surface mounted. If an in-wall or
ush mount look is desired build
the interior wall out into the room.
!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 ensure 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 applicable 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 gaso-
line, or other ammable vapors or
liquids in the vicinity of the heater.
1. Select a location that is not
susceptible to moisture and
is away from drapes, furniture
and high traf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 box and
remove all packaging materials
before installation.

in convenience. 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 in-
jury to persons, always use a
licensed electrician.

circuit on which the replace is
to be installed has the power
cut off at the service panel
