absence of local codes and ordinances, the power 
supply connection shall be in accordance with the 
National Electric Code.
Observe all governing codes and ordinances when 
grounding. In the absence of these codes or 
ordinances observe National Electrical Code ANSI/
NFPA No. 70 current issue. See page 16 for grounding 
method.
Electrical wiring diagrams and schematics have been 
placed in the toe kick area of the range for access by a 
qualified service technician.
The Dual Fuel Ranges may be connected to a 240/208 
VAC power supply.
The range must be connected to the power supply utilizing 
one of the following methods. For all methods of 
connection, the length of the cord or conduit/wiring must 
allow the unit to be slid completely out of the cabinet 
without having to unplug or disconnect the unit from the 
power supply. Recommended minimum free length of cord 
or conduit is four feet. Electrical installations and grounding 
must be in accordance with all local codes and ordinances, 
and/or the National Electric Code, as applicable.
4-CONDUCTOR CORD — NORMALLY, A UNIT 
MUST BE CONNECTED TO THE POWER SUPPLY 
WITH A 3-POLE, 4-CONDUCTOR CORD KIT RATED 
125/250 VOLTS, 50 AMPERES, AND MARKED FOR 
USE WITH RANGES. 
The cord kit must be attached to 
the range junction box with a strain relief which will fit a 
1" diameter hole. If not already equipped, the cord 
must have 1/4" faston closed-loop lugs attached to the 
free ends of the individual conductors, preferably 
soldered in place.
PERMANENT CONNECTION (HARD WIRING) — 
Units may be hard wired to the power supply. The 
installer must provide approved flexible aluminum 
conduit, 3/4" trade size, maximum 6 feet long. Locate 
the junction box on the rear of the unit and remove 
cover. Refer to Figure 10. Remove the ground strap 
retaining screw and bend the ground strap up. Refer to 
Figure 14. The conduit must be installed to the junction 
box using an approved conduit connector.
Wiring for the unit is to be brought into the junction box 
through the conduit. The ends of the wiring must have 
1/4" faston closed-loop lugs attached, preferably 
soldered in place. Make the connections to the terminal 
block provided. Secure the ground lead to the junction 
box with the screw previously used to secure the 
ground strap. Refer to Figure 13. The free end of the 
conduit must be connected to a junction box provided 
in the gas and electrical supply zone, as shown in 
Figure 3a on page 8.
