Read all instructions before us-ing this electric fireplace.
This fireplace 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.
DANGER: High temperatures may be generated under certain ab-normal conditions. Do not partially or fully cover or obstruct the front of this heater.
Extreme caution is necessary when any heater is used by or near children or invalids and whenever the unit is left operating and unattended.
Young children should be supervised to ensure that they do not play with the appliance.
The appliance is not intended for use by young children or infirmed persons without supervision.
Do not operate the unit after it malfunctions. Disconnect power at the service panel and have the unit inspected by a reputable electrician before reusing.
If the supply cord is damaged, it must be replaced by the manufacturer, or its service agent, or a qualified person in order to avoid a hazard. Contact Dimplex Technical Service for obtaining a replacement cord at 1-888-346-7539.
Do not use outdoors.
Never locate a fireplace where it may fall into a bathtub or other water container.
To disconnect the fireplace, turn the controls off, and turn off the power to the heater circuit at main disconnect panel.
Do not run the cord under carpeting. Do not cover cord with throw rugs, runners, or the like. Arrange cord away from traffic area and where it will not be tripped over.
Do not locate the heater immediately below a fixed socket outlet.
Do not insert or allow foreign objects to enter any ventilation or exhaust opening as this may cause an electric shock or fire, or damage to the heater.
To prevent a possible fire, do not block air intakes or exhaust in any manner.
All electrical heaters have hot and arcing or sparking parts inside. Do not use in areas where gaso- line, paint, or flammable liquids are used or stored.
Use this fireplace only as described in this manual. Any other use not recommended by the manufacturer may cause fire, elec-tric shock or injury to persons.
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).
Do not burn wood or other materials in the electric fireplace.
Do not strike the fireplace glass.
Always use a certified electrician should new circuits or outlets be required.
Always use properly grounded, fused and polarized outlets.
Disconnect all power supplies before performing any cleaning, maintenance or relocation of the unit.
When transporting or storing the unit and cord, keep in a dry place, free from excessive vibration, and store so as to avoid damage.
WARNING: Remote control contains small batteries. Keep away from children. If swallowed, seek medical attention immediately.
WARNING: Do not install battery backwards, charge, put in fire or mix with used or other battery types – may explode or leak caus-ing injury.

Fireplace Installation

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.

CAUTION: Ensure installation does not allow fireplace 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 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 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 fire, or 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 fire, electric shock and injury to persons.
WARNING: To reduce the risk of fire, do not store or use gasoline or other flammable vapors or liquids in the vicinity of the heater.

Select a location that is not susceptible to moisture and is away from drapes, furniture and high traffic.
For ease of electrical hook up you may wish to locate the fireplace near an existing outlet (for plug-in convenience) (refer to NOTE 1).
Remove fireplace, front glass and hardware from the box and remove all packaging materials before installation.
Store the fireplace in a safe, dry and dust free location until you are ready to install the fireplace.

Grounding Instructions

This product must be grounded. If it should malfunction or break down, 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 qualified 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 fit the outlet, have a proper outlet installed by a qualified electrician.
This product is for use on a nominal 120-volt circuit and has a grounding plug that looks like the plug in Figure 1. Make sure that the product is connected to an outlet having the same configuration as the plug. No adapter should be used with this product.

Hardwire Installation

The fireplace is provided with a three-prong plug installed for plug-in convenience. Hardwiring the fireplace is also an option for any installation.

Remove the two-wire access covers off of the unit at the front to access the wire connections.(Figure 4)
Pull the wires and connectors out of the back opening.
Unscrew the three wire connectors inside the electrical box and separate the wires.
Install the supplied hardwire bracket (with the ½” wire hole) onto the firebox. (Figure 3)
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 supplied).
Connect the black wire (L) from the unit to the live wire from the power supply using one of the wire connectors removed in step 4.
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.
Connect the green wire (G) from the unit to the ground wire from the power supply using the third wire connector from step 4.
