18-28-506.3.13.2 Termination through an exterior wall.
   Exhaust outlets shall be permitted to terminate through exterior walls where the smoke, grease, gases, vapors, and odors in the discharge from such terminations do not create a public nuisance or a fire hazard. Such terminations shall not be located where protected openings are required by the Chicago Building Code. Other exterior openings shall not be located within 10 feet (914 mm) of such terminations. Horizontal runs shall be direct from hood to exterior wall termination, without passing through any wall separating one business enterprise from another.
