We study the constraints on the hierarchy of gauge-boson mass scales from low-energy physics in the maximal grand unification model based on the group SU(16). We show that for certain values of sin/sup 2/theta/sub W/(m/sub W/) and ..cap alpha../sub strong/(m/sub W/) allowed by low-energy data, the intermediate mass scales associated with local B-L symmetry and right-handed gauge interactions may be as low as 10/sup 3/ GeV. We use a previously suggested method to study the Higgs-boson effects on these mass scales. We also discuss the implications for baryon nonconservation in this model and point out that the most likely ..delta..Bnot =0 processes in simple versions of the model are the ones obeying ..delta..(B-L) = 0 selection rule.
