Here we present the complete manual for the simulation of 14 dierent rare semileptonic channels
of the B^{\pm}-, B^0_d- and B^0_s-meson decays using the Monte Carlo EvtGen generator package (LHCb
version).We present also the description of a few non-documented or not-well-documented features
and restrictions of EvtGen package which were used for the simulation.
