The study presents millimeter and submillimeter images of the bipolar nebula S106 which resolve the structure of the circumstellar material around the exciting star S106 IR. There is a bright, previously undetected FIR point source in the dust lane which is not detected at 20 microns, suggesting that it is an extremely embedded object of moderate luminosity (30-1000 solar luminosities). This object may be a very young protostellar companion to S106 IR. Maps of the C(O-18) J = 1-0 and CS J = 3-2 emission are presented; these correlate well with the continuum maps. It is suggested that most of the circumstellar dust and gas is warm and that no significant molecular depletion has occurred. The hot circumstellar gas as traced by the CO J = 6-5 line is also mapped. A lower limit to the temperature of this component is estimated at 165 K, and its mass is found to be greater than 0.05 of the total molecular gas mass.
