Operation: While enjoying the ambiance of your fire pit, the system is at work monitoring flame status, internal temperatures / voltages and other safety parameters. If flame loss does occur, the system will turn off all gas flow, and then restart by automatically commencing Start sequence. Shut Down: To turn OFF the fire pit simply use wall switch, remote control or whole house system. Features: Fully Assembled- ready to install. Control components are protected within valve box.
