Electrical Connection

A 15 amp, 120 Volt, 60 Hz circuit with a properly grounded outlet is required. Preferably, the fireplace will be on a dedicated circuit as other appliances on the same circuit may cause the circuit breaker to trip or the fuse to blow when the heater is in operation. The unit comes standard with a 6 ft. (1.8 m) long three wire cord, exiting the right side of the fireplace. Plan the installation to avoid the use of an extension cord.

Extension cords are for temporary use only. If an extension cord must be used, it must be UL/CSA certified, rated at 15A (1875W), 125V maximum with 14 AWG minimum and con- structed of two current carrying conductors with ground. A heavy duty extension cord with the shortest length possible for the connection is recommended and must not be longer than 50 ft. (15.2 m). Do not coil or cover the extension cord.

Electrical outlet wiring must comply with local building codes and other applicable regulations to reduce the risk of fire, electrical shock and injury to persons.

Do not use this fireplace if any part of it has been under water. Immediately call a qualified service technician to inspect the fireplace and replace any part of the elec- trical system which has been under water.

Grounding Instructions

This heater is for use on 120 volts. The cord has a plug as shown at A in Figure 1. An adapter as shown at C is available for connecting three-blade grounding- type plugs to two-slot receptacles. The green ground- ing lug extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box. The adapter should not be used if a three- slot grounded receptacle is available.

Direct (Hard) Wiring Electric Fireplace

WARNING:This procedure must be conducted by a qualified electrician, in accordance with National and local codes. In the U.S.A., the installation must con- form to the National Electrical Code, ANSI/NFPA No.

70.In Canada, the installation must conform to the current CSA C22.1 Canadian Electrical Code.

WARNING: Make sure the power to the unit is off, and the power cord is unplugged from the wall outlet before proceeding with this conversion. Failure to do so may result in property damage, personal injury or loss of life.

This instruction is intended as a guide for replacing the power cord supplied with Models HEF22/26/33 electric fireplace with direct (hard) wiring.

NOTE: When direct wiring this appliance, it must be connected to a 15 Amp dedicated circuit breaker or fuse in the electrical panel of the dwelling. The cable between the circuit/fuse panel and the fireplace must meet all local and national codes, and in no case shall the wires be less than 14 gauge.

1.Make sure the power to the unit has been turned off, the power cord is unplugged from the wall outlet and the unit has cooled down if it has been operat- ing.

2.Follow Steps 3 through 6 in “Replacing Light Bulbs” section, Page 7, to gain access to control panel behind the touchpad controls.

3.Locate where the power cord enters the control compartment on the right hand side of the unit. Using wire cutters, cut the power cord within three inches (75mm) of the point where it exits the cabi- net.

4.Carefully separate the three (3) wires of the power cord into separate wires by gently pulling them apart. DO NOT use a knife, as this may expose bare conductor. The hot wire is connected on the right hand side and is terminated with a 90° termi- nal (marked as “power” on the control board). The neutral wire is connected on the left hand side and is terminated with a straight terminal marked as “Neutral” on the control board. The green ground wire is attached to a ground stud.

5.Using wire strippers, strip approximately 5/8" (15mm) from the ends of the hot and neutral wires.

6.Using a wrench, remove the #10-24 hex nut from the ground stud where the green wire from the power cord is attached. Remove and discard the green wire. Reinstall the nut but do not tighten yet.

7.While standing on the right side of the unit, locate the power cord where it exits the cabinet. Using pli- ers, gently cut and remove the power cord. Dispose of the power cord.
