dance with all applicable local codes and ordinances by a qualified electrician.
In the 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 20 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.
CAUTION
The appliance must be isolated from the gas supply piping system by
closing its individual manual shut-off valve during any pressure testing of
the gas supply piping system at test pressures equal to or less than 1/2
psig (3.5 kPa.).
The appliance and its individual shut off valve must be disconnected from
the gas supply piping system during any pressure testing of the system
at test pressures in excess of 1/2 psig (3.5 kPa.). When checking the
manifold gas pressure, the inlet pressure to the regulator should be at
least 6" W.C. (14.9 mb) for natural gas or 11" W.C. (27.4 mb) for propane.
Do not attempt any adjustment of the pressure regulator.
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" fas-
ton closed-loop lugs attached to the free ends of the individual conductors, pref-
erably soldered in place.
• PERMANENT CONNECTION (HARD WIRING) - Units may be hard wired to
the power supply. The installer must provide approved flexible aluminum con-
duit, 3/4" trade size, maximum 6 feet long. Locate the junction box on the rear of
the unit and remove cover. Refer to Figure 9. Remove the ground strap retain-
ing screw and bend the ground strap up. Refer to Figure 11. 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 12. 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 9.
