Modular gas appliance system

A method for reducing a gas flow rate to a modular cooking cartridge in a gas appliance, the method comprising the steps of:

• directing a flow of gas at a first gas flow rate through a first gas orifice;
• and
• coupling an adapter with the modular cooking cartridge and the first gas orifice, the adapter further including a second gas orifice downstream of said first gas orifice capable of directing said flow of gas to said modular cooking cartridge at a second gas flow rate, said second gas flow rate being less than said first gas flow rate.

A method of adapting a gas appliance with a plurality of locations for receipt of modular cooking units, including modular burner units and modular grilling units requiring different maximum flow rates, to interchangeably receive modular burner units and modular grilling units at each of the plurality of locations, comprising the steps of:

• providing a gas supply line at each of the plurality of locations with a flow controlling gas orifice providing the maximum gas flow rate for the modular cooking units;
• and
• providing each modular grilling unit to be used with the cooktop with an adapter including a flow controlling gas orifice providing the lower maximum gas rate for the modular grilling unit.
