Dimensions of the unit: 188.3cm x 49.5cm
Unit requires a minimum of three (3) wall studs in order to ensure a secure installation

Three possible installation methods:

Installation method: Surface mount; In-wall Recessed; or Flush mount
Hardwired or plug-in method 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, 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.

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).
NOTE 1: A 10 Amp, 230-240 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.
Remove fireplace, front glass and hardware from 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. The fireplace is packaged with a three prong plug installed for plug-in convenience. Hard wiring the fireplace is also an option by removing the plug from the factory fittqed cord and completing the wiring according to National and Local Elecrical Codes. It is necessary to allow disconnection of the appliance from the supply after installation. The disconnection can be achieved by having the plug accessible or by incorporating a switch in the fixed wiring in accordance with the wiring rules.

WARNING: Do not attempt to wire your own new outlets or circuits. To reduce the risk of fire, electric shock or injury to persons, always use a licensed electrician.

NOTE: It is recommended that the mounting bracket be installed 56 in. (142 cm) off of the ground to maintain an optimized viewing angle of the flame.
Hold the wall mounting brack-et, with the bubble level on the top, on the wall so that the bubble on the level is centered between the two black lines.
Mark the 4 mounting screw locations, on the wall, ensur-ing that the wall bracket stays level. (Figure 2)
In locations where the screws are being installed only into drywall, install the supplied wall anchors before installing the screw (predrill if required).
Secure the wall bracket to the wall using the supplied 1½ in.(3.8 cm) mounting screws and washers into the wall and/or wall anchors.
