Ventilation System: The cooktop must be used in conjunction with a suitable ventilation system.
Accessibility: The power cord, gas shut-off valve, and gas pressure regulator must be accessible from the front of the cabinet after installation.

Maintenance Features:

Leak Testing: Leak testing of the appliance must be conducted according to manufacturer's instructions after gas supply connection. A soap solution should be used; never a flame.
Burner Cap Placement: After electrical connection, burner caps should be placed in their correct sized notched positions.
Flame Characteristics Check: After installation, check the operation of electric igniters and observe flame characteristics. The flame should be blue with no yellow tip.
Gas Pressure Regulator: Do not attempt any adjustment of the pressure regulator, except for conversion to propane.
Gas Shut-off Valve: An individual gas shut-off valve must be installed in an easily accessible location under the unit. This valve is crucial for isolating the appliance from the gas supply piping system during pressure testing or service.
Cleaning: While not explicitly detailed in the provided excerpts, general appliance maintenance would include cleaning the cooktop surface and burner components.

Important Safety and Installation Notes:

Installation must conform to local codes or, in their absence, with the National Fuel Gas Code, ANSI Z223.1.
Electrical grounding must conform to local codes or, in their absence, with the National Electrical Code ANSI/NFPA 70. In Canada, installation must conform to CAN 1-B149.1 and .2.
The appliance is factory equipped with a 3-prong grounding plug; the third ground prong must never be cut or removed. It must be plugged into a matching grounding type receptacle on a correctly polarized 120-volt circuit.
Improper installation, adjustment, alteration, service, or maintenance can cause injury or property damage. Consult a qualified installer, service agency, manufacturer, or gas supplier for assistance.
For solid surface material installations (e.g., Surell™, Corian®), heat reflective tape (e.g., Scotch® Aluminum Foil Tape #425 or #427) must be applied around the cutout, folding over the top and sides, ensuring it extends beyond the outermost flange of the cooktop. A wooden block should be inserted between the end of the adjusting screw and the bottom of the countertop for these installations.
Before connecting the electrical cord, ensure all controls are in the OFF position.
Before connecting the 5-foot supply cord to the wall receptacle, ensure the gas shutoff valve and all burner controls are in the OFF position.
The gas pressure regulator must be installed after the rough-in box is in its permanent position.
For Massachusetts installations, specific requirements apply: the shut-off valve must be a "T" handle gas cock, the flexible gas connector must not be longer than 36 inches, and the unit is not approved for installation in a bedroom or bathroom unless it is direct vent.
