• Direct (Hard) Wiring Electric Fireplace
This instruction is intended as a guide for replacing the power cord supplied with
Models EF22/26/33/36 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 oper-
ating.
2. Follow Steps 3 through 6 in “Replacing Light Bulbs” section, Page 8, 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 (75
mm) of the point where it exits the cabinet.
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° terminal (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" (15 mm) 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 pliers, gently cut and remove the power cord. Dispose of the
power cord.
8. Using a slotted screwdriver, remove the 7/8" (22 mm) diameter knockout from
the right hand side of the cabinet above where the strain relief was located.
9. Route the electrical cable from the breaker/fuse panel through the 7/8" (22mm)
diameter hole and secure to the cabinet using an approved clamp. The power
wires should extend approximately 6" (152mm) into the control compartment.
10. Connect the ground wire from the power cable by wrapping it around the
ground stud of the unit and securing it using the #6-32 nut.
11. Using a wire nut, connect the hot lead (black), of the power cable to the power
cord wire that ends in 90° terminal (on the control board side, it ends on your
right hand side). Similarly, connect the neutral wire (white), of the power cable
to the power cord ending with the straight terminal (on the control board side, it
ends on your left hand side) using a wire nut. It is recommended that the wire
nuts be taped to the wires, using electrical tape, as an extra safety measure.
12. Visually check that none of the wires in the control compartment have been dis-
lodged from the controls. If they have, use the wiring diagram on the unit or in
the instruction manual to replace them in their proper location.
13. Turn the power to the unit on at the breaker/fuse panel. Place the unit into oper-
ation and check to make sure that all of the systems are working properly.
