In this contribution we present a brief summary of the detailed study we are carrying out of the far-IR spectrum of the Sgr B2 complex. This molecular cloud represents an interesting burst of massive star formation in the Galactic Center and may be representative of other active galactic nuclei. Our ˜50-190 μm Line Survey includes all the LWS-FP data base observations we are using in the analysis of the Sgr B2 M central condensation. We also present LWS-grating spectra covering a 9'×27' (˜25×70 pc) region around the central M source that completes our analysis of Sgr B2. The combination of both far-IR molecular spectroscopy and radiative transfer tools is giving us a more accurate picture of the warm gas in the outer layers of the complex. This warm gas is poorly traced by mm and submm observations.
