The moving H-alpha emission line profiles formed in the SS 433 jets are simulated under the assumption that the jet gas is heated by the collimated emission from the accretion disk. It is shown that, depending on the moment of observation, the jet's location in the cone of this radiation changes, which can affect the moving line profiles. A limit on the cone opening angle of not less than 14 deg is obtained from the modeling. The observed line profiles are in agreement with the assumed jet heating model. The required luminosity of the collimated emission is not less than 3 x 10 exp 39 ergs/s.
