Wherever practicable, vacancies shall be filled by promotion. Any advancement in rank or increase in salary beyond the limits fixed for the grade shall constitute a promotion. Lists shall be created and promotions made therefrom of candidates in the same manner as in original appointments, except that the Commission shall certify the names and addresses of the three candidates standing highest on the eligible list for the class or grade to which the promotional position belongs and the appointing authority shall appoint one of the three persons whose names are certified; and provided, however, that less than three shall constitute an eligible list, and the appointing authority shall appoint from the eligible list.
