When using electrical appliances,
basic precautions should always
be followed to reduce the risk of
fire, electric shock, and injury to
persons, including the following:
① Read all instructions before us-
ing the electric replace.
②The heater is hot when in use.
To avoid burns, do not let bare
skin touch hot surfaces. The trim
around the heater outlet becomes
hot during heater operation.
③ Extreme caution is neces-
sary when any heater is used by
or near children or invalids and
whenever the unit is left operating
and unattended.
④ Always unplug the electric
replace when not in use.
⑤ Do not operate any heater after
it malfunctions. Disconnect power
at the service panel and have the
heater inspected by a reputable
electrician before reusing.
⑥ Do not operate any unit with
a damaged cord or plug, or if the
heater has malfunctioned, or if
the electric replace has been
dropped or damaged in any man-
ner, contact Dimplex Technical
Service at 1-888-346-7539.
IMPORTANT INSTRUCTIONS
⑦Do not use outdoors.
⑧ The electric replace is not
intended for use in bathrooms,
laundry areas and similar indoor
locations. Never locate heater
where it may fall into a bathtub or
other water container.
⑨ Do not run the cord under
carpeting. Do not cover cord with

c area and where it will not be
tripped over.
⑩ To disconnect the unit, turn the
controls off, then remove the plug
from the outlet
⑪ Do not insert or allow foreign
objects to enter any ventilation
or exhaust opening as this may
cause an electric shock or re, or
damage to the heater.
⑫ To prevent a possible re, do
not block air intake or exhaust in
any manner.
⑬ All electrical heaters have
hot and arcing or sparking parts

SAVE THESE INSTRUCTIONS
in this manual. Any other use not
recommended by the manufactur-
er may cause re, electric shock
or injury to persons.
⑮ To reduce the risk of electric
shock, this appliance has a polar-
ized plug (one blade is wider than
the other). This plug will t in a
polarized outlet only one way. If
the plug does not t fully in the
outlet, reverse the plug. If it still
does not t, contact a qualied
electrician to install the proper
outlet. Do not change the plug in
any way.
⑯ Always plug heaters directly
into a wall outlet/receptacle.
Never use with an extension cord
or relocatable power tap (outlet/
power strip).
⑰ Do not burn wood or other ma-
terials in the electric replace.
⑱ Do not strike the replace
glass.
⑲ Always use a certied electri-
cian should new circuits or outlets
be required.
⑳ Always use properly grounded,
fused and polarized outlets.
㉑ Disconnect all power supply
before performing any cleaning,
maintenance or relocation of the
unit.
㉒When transporting or stor-
ing the unit and cord, keep in a

ing of 24 ½ in. (622 mm) wide
X 18 ¼ in. (463.6 mm) high
X 8 ⅞ in. (225.5 mm) deep.
(Figure 1)
Option #1 - The power cord can
be lead from behind the trim
and along the wall to an outlet
near the replace.
Option #2 - A new outlet can be
installed inside the new frame
construction. Plug the unit into
a 15 Amp/120 Volt outlet.
!NOTE: A 15 Amp, 120 Volt
circuit is required. A dedicated
circuit is preferred but not es-
sential in all cases. A dedi-
cated 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 the current rating
of the circuit breaker.
Option #3 - Hardwire
1. Wire a dedicated, properly
fused circuit with 120 Volt, 15
Amp rating. Allow up to 8 feet
of service cable for connect-
ing power supply to junction
box on replace when install-
ing after nishing wall.
CAUTION: Use two conduc-
tor, non-metallic sheath cable
with ground wire (3 wires total)
for the incoming power supply on
replace inserts. Use appropriate

wire to meet local and national
electrical codes for rated power
consumption.
2. Remove the outer jacket and
strip the individual conductor
from the end.
3. Loosen the screw securing
the junction box cover and
remove the cover.
4. Take the cables out from the
junction box, loosen the two
wire twist nuts and remove
the cord set (Figure 2).
5. Route the power supply wire
through the knockout on sup-
plied alternative junction box
cover and secure with a wire
clamp (not supplied) (Figure
3).
6. Connect the black wire (live)
from the unit to the black wire
from power supply (Figure 3).
7. Connect the white wire
(neutral) from the unit to the
white wire from power supply
(Figure 3).
8. Connect the green wire
(ground) from the unit to the
green wire from power supply
(Figure 3).

Manual Controls
A. 3-Position Switch
The switch has two ON positions
marked. The "--" position is for
manual operation. In this position
the built-in remote control is by-
passed. The "=" position is for op-
erating the unit with the provided
remote control.
When the switch is in the center
“o” position the unit is off.
B. Heater ON/OFF Switch
The Heater ON/OFF Switch sup-
plies power to the heater fan and
the heater element. When the
switch is in the ON position the
heater operates if the thermostat
calls for heat.
C. Heater Thermostat Control
To adjust the temperature to your
individual requirements, turn the
thermostat control clockwise all
the way to turn on the heater.
When the room reaches the de-
sired temperature, turn the ther-
mostat knob counter-clockwise
until you hear a click. Leave in
this position to maintain the room
temperature at this setting. For
additional heat, turn clockwise un-
til you hear the click again and the
heater will turn on.
!NOTE: The heater on your
replace may emit a slight,
harmless odor when rst used.
This odor is a normal condition
caused by the initial heating of
internal heater parts and will
not occur again.
Resetting the Temperature
Cutoff Switch
Should the heater overheat, an
automatic cut out will turn the re-
place off and it will not come back
on without being reset. It can be
