Some dynamic properties of a fourteen-vertex model defined on the bcc(001) surface are investigated with Glauber kinetics. Exact results are given for small-size versions of the model. Using Monte-Carlo simulations on large systems and the Becker-Doering law behaviour of the growth rate in the 2D-nucleation theory, a non-equilibrium phase diagram is presented.
