the Gas-On LED will illuminate.
ON = Gas On / OFF = Gas Off

This LED will illuminate for approximately 30 seconds when the panel is checking the integrity of the gas
installation upon start up.

When the panel detects a gas leak on start- up, the LED will illuminate and the gas valve will remain
closed.
OFF = OK / ON = gas proving test failed

The LED will illuminate when the incoming gas pressure drops below 0.17psi for 10 seconds and the gas
valve will close.
