partially, fully cover, or obstruct
the front of this heater.
③Extreme caution is necessary
when any heater is used by or
near children or invalids and
whenever the unit is left operating
and unattended.
④Young children should be
supervised to ensure that they do
not play with the appliance.
⑤ The appliance is not intended for
use by young children or inrmed
persons without supervision.
⑥Do not operate any heater after
it malfunctions. Disconnect
power at service panel and have
heater inspected by a reputable
electrician before reusing.
IMPORTANT INSTRUCTIONS

SAVE THESE INSTRUCTIONS
⑮Use this heater only as
described in this manual. Any
other use not recommended by
the manufacturer may cause
fire, electric shock, or injury to
persons.
⑯ To reduce the risk of electric
shock, this appliance has a
polarized plug (one blade is
wider than the other). This plug
will fit in a polarized outlet only
one way. If the plug does not fit
fully in the outlet, reverse the
plug. If it still does not fit, contact
a qualified electrician to install
the proper outlet. Do not change
the plug in any way. Always plug
heaters directly into a wall outlet/
receptacle. Never use with an
extension cord or relocatable
power tap (outlet/power strip).
⑰Do not burn wood or other
materials in the electric replace.
⑱ Do not strike the replace glass.

/
16
"
(128 cm) x 19½"(49.5 cm)
• Unit requires a minimum of two wall
studs in order to ensure a secure
installation
There are three possible mounting
methods:
• Surface mount (pg. 12);
• Partial recess (pg. 13);
• Flush mount (pg. 14),
and any of these have the option of
being hardwired or plugged directly
into the wall outlet.
WARNING: The top of the
replace 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 codes.
!
NOTE 1: A 15 Amp, 120 Volt
circuit is required. A dedicated
circuit is preferred but not essential
in all cases. A dedicated circuit will
be required if, after installation, the
circuit breaker trips or fuse blows
on a regular basis when the heater
is operating. Additional appliances
on the same circuit may exceed
Fireplace Installation
the current 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 gasoline,
or other ammable vapors or
liquids in the vicinity of the heater.

Grounding Instructions
This product must be grounded. If it
should malfunction or breakdown,
grounding provides a path of least
resistance 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 grounded in accordance
with all local codes and ordinances.
DANGER: Improper connection
of the equipment-grounding
conductor 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
120-volt circuit and has a grounding
plug that looks like the plug in Figure
3. Make sure that the product is
connected to an outlet having the
same conguration as the plug. No
adapter should be used with this
product.

• Plug into an existing outlet or
install an outlet nearby.
• Hardwire the replace - follow the
hardwiring instructions on page 9.
3. Remove the partially reective
glass from the replace:
• Lay the replace on its back.
• Remove the two Phillips screws
from each of the two glass
brackets (Figure 3, page 9).

keyholes line up with a wall stud
(keyholes are spaced at 4 in. (10.2
cm) centers), mark the location
of the four screw locations on the
wall (through the keyholes).
6. Remove the fireplace from the wall
and store it in a safe place away
