How is fuel supplied to the pilot assembly on a gas furnace?

In a gas furnace, fuel is supplied to the pilot assembly through a gas line that connects to the gas valve. When the thermostat calls for heat, the gas valve opens, allowing gas to flow to the pilot assembly. The pilot, which is a small flame, ignites the gas, creating a flame that can then light the main burners when the furnace is operating. This process ensures that the furnace operates efficiently and safely.
