Narrative:

Shortly after becoming airborne off runway 5L at cle, approximately 100 ft AGL, we observed a 'fire warning left engine.' we reduced the left throttle to idle after passing 400 ft AGL. The fire warning ceased and the captain tested the fire warning system to ensure its validity. We then requested and received permission to enter a downwind leg and descend back to VMC conditions. We accomplished a visual approach to runway 5R at cle with the left engine at idle power. After clearing the runway, we shut down the left engine, started the APU, and then shut down the right engine. We then had our ramp personnel tow us to the gate, since the cleveland fire department personnel had informed us that there was no external evidence of any fire or smoke. Cleveland ATC did an excellent job of expediting our return to the airport. Total airborne time was 7 mins. Supplemental information from acn 259404: declared emergency, contacted departure, turned downwind, reduced thrust left engine to idle. Fire warning ceased. Bleed air leak apparent problem. First officer was flying. He continued flying. After clearing on 2ND high speed, pulled fire handle, got visual confirmation of clean engine (no smoke/fire) from fire chief. Departure controller remained with us throughout -- perfect vectors, airport location advisories, and altitude assignments. All requests by crew were immediately answered or provided. Procedurally we were very busy, but finished important checklists correctly.
