After completing run No. 15, check flame heater system for operation and fuel leaks by activating while idling and feeling for warm intake elbow. Check smoke generating system fuel flow. If the engine will be used in 30 days, remove from test and cap or plug all openings. If the engine will be stored longer than 30 days, preserve as directed in WP 0020 00.
