Electronic Ignition Module/Gas Control Valve
When the thermostat calls for heat it completes a circuit to the
electronic ignition module. The module sends an electrical signal
which ignites the pilot, and then opens the gas valve.
When the flame is firmly established, the igniter shuts off. If there
is a malfunction, the gas valve automatically shuts off the gas.
