We present submillimeter and millimeter line and continuum observations of the region around LkH-alpha 198 and V376 Cas. The continuum data reveal the presence of a very cool object, LkH-alpha 198 MM located approximately 19 sec northwest of LkH-alpha 198. LkH-alpha 198 MM is not visible in the near-IR. The CO maps suggest that the mm-source, rather than LkH-alpha 198 or its IR companion LkH-alpha 198B, may drive the large CO outflow seen in this cloud or that both drive outflows which are roughly aligned with each other. In addition V376 Cas appears to power a small bipolar CO outflow.
