We carefully analyze the recently suggested grand unified model based on the gauge group SU(15). 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 a massless gauge boson corresponding to the unbroken baryon-number symmetry present in the original model.
