Based on the new spectroscopic and photometric data, a model of the symbiotic star EG And has been worked out. New orbital elements were derived. An external envelope close to the EG And system and rotating with it has been suggested to explain strong phase dependent variations of the spectrophotometric parameters and radial velocites of the emission Hγ line as well as the two minima in the U light curve.
