• For these gas range models, a neutral supply
wire must be provided from the power source
(breaker/fuse panel) because critical range com-
ponents, including the surface burner spark re-
ignition modules, require 120 VAC to operate
safely and properly. 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 obliga-
tion 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 ab-
sence of local codes and ordinances, the power
supply connection shall be in accordance with
the National Electrical Code.
Dedicated 20 AMP service is required for range with electric griddle.
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 (3.5kPa.).
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 (3.5kPa.).
When checking the manifold gas pressure, the inlet pressure to the regulator should be at leas 6.0" (14.9
mb) W.C. for natural gas or 11.0" (27.4 mb) for propane.
Do not attempt any adjustment of the pressure regulator.

• 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 have
been placed in the toe kick area of the range for
access by a qualified service technician.
• 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 remove the ground prong. It must be
plugged into a matching grounding type recep-
tacle to avoid electrical shock. If there is any
doubt as to whether the wall receptacle is prop-
erly grounded, the customer should have it
checked by a qualified electrician.
• Installer - show the owner the location of the
circuit breaker or fuse. Mark it for easy reference.
