C.2

The area to be protected should be the cook top surface of a residential stove within the dimensionslisted in the manufacturer’s design, installation, and maintenance manual.

C.3

Each protected cook top should be provided with a listed fire detection device or devices specified in themanufacturer’s design, installation, and maintenance manual to automatically actuate the extinguishingsystem.

C.4

Manual actuation should be provided in the path of egress as per the manufacturer’s design, installation,and maintenance manual.

C.5

Only the type of hose/pipe and fittings listed in the manufacturer’s design, installation, and maintenancemanual and provided as part of the pre-engineered extinguishing system should be used.
