We carefully reanalyzed the recently suggested grand unified model based on the gauge group SU(15). We find that the unification scale is not as low as predicted before. We discuss various bounds on the scales imposed by rare processes. We point out that baryon number is part of the gauge symmetry of the model. We propose changes that get rid of gauge anomalies and a massless gauge boson corresponding to the unbroken baryon number symmetry present in the original model.
