2. Turn the gas regulator valveâs knob to âPilot,â press down on it and hold it down. This starts the flow of gas to the pilot burner. On some water heater models, you press and hold down a separate red button to start the pilot burner gas flow.. Turn the gas regulator valveâs knob to âPilot,â press down on it and hold it down.

Definition of Conduction. the result of collisions between molecules; when one end of an object is heated, the molecules vibrate faster and the energy is transferred to their neighbors. Definition for Conduction :1. Thermal conduction the transfer of heat between two solid materials that are physically touching each other.2.
Conduction is the process of heat transfer by direct contact of the food to the heat source. This usually occurs at higher temperatures, thus creating a searing effect. Infrared grilling is a good example of conduction. Conduction also occurs at the grilling surface (grill grates). Convection occurs when the heat is carried to the food that is being cooked. The use of some type fluid such as air, water and even oil will act as a carrier for heat transfer. In grilling, this process is also termed âindirect grillingâ.
