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.
Conductor or conduction may refer to: In physics 1  : Electrical conductor, an object allowing the flow of electric charge. 2  Electrical conduction, the movement of charged particles through an electrical conductor.3  Fast ion conductor, a solid-state electrical conductor which conducts due to the movement of ions. Electrical conduction, the movement of charged particles through an electrical conductor. 2  Fast ion conductor, a solid-state electrical conductor which conducts due to the movement of ions. 3  Conduction (heat) , the transfer of thermal energy through matter.
