• A neutral supply wire must be provided from the power
source (breaker/fuse panel) because critical range
components, including the surface burner spark
reignition modules, require 120 VAC to operate safely
and properly.
WARNING:
An improper 120 VAC power supply will cause
malfunction, damage to this appliance, and
possibly create a condition of shock hazard.
• If the correct power supply circuit is not provided, it is
the responsibility and obligation of the installer and
user to have proper power supply connected. This
must be accomplished in accordance 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 Electrical 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.
• Electric wiring diagrams and schematics are attached
behind the toe kick panel of the range for access by a
qualified service technician.
Important:
For all gas ranges with electric griddle, dedicated 20 AMP
service is required for proper operation.
Before you plug in an electrical cord, be sure all controls
are in the OFF position.
For appliances equipped with a cord and plug, do not cut or

Step 7: Backguard Installation

The backguard must be attached before sliding the range
into the final installed position. A Low Back or Pot-and-Pan
Shelf must be installed when there is less than a 12"
clearance between a combustible back wall and the back of
the range above the cooking surface. (See Figure 2 on
page 6).
An Island Trim is available for covering the backguard area
of the range for island installations; however, the Island
Trim can only be used where there is a minimum of 12"
horizontal clearance between a combustible back wall and
the back of the range. (See Figure 2 on page 6).
Align the back panel of accessory with the flange on the
range side panel right and left rear corners. The backguard
is inserted inside the guide channels on the back of the
range. (See Figure 9.)
Make sure the backguard's front face is outside of the
flange at the back of the range.
Install screws through the backguard's front face panel into
the flange on the range. The 30-inch and 36-inch ranges
will use three (3) screws and 48-inch range will use four (4)
screws.
Install four (4) screws to secure the backguard's back panel
to the guide channels on the back of the range. Install one
