• A neutral supply wire must be provided from the
power source (breaker/fuse panel) because criti-
cal range components, 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 responsibil-
ity and obligation of the installer and user to have
proper power supply connected. This must be
accomplished in accordance with all applicable
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 remove the ground prong. It must be plugged into
a matching grounding type receptacle to avoid electrical shock. If there is any doubt as to whether the wall
receptacle is properly 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.
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 least 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.
