International Code Council Updated M2 Exam Questions and Answers by maja

Under the ICC administrative provisions used with the mechanical code, one approved set is retained by the code official, and one approved set is returned to the applicant. The returned set must be kept on the site of the building or job while the authorized work is in progress. That directly matches Option A . It does not require return to the architect, filing with the county clerk, or retention for one year after completion.

The IMC specifically provides that Type I hoods used over extra-heavy-duty cooking appliances shall not cover other appliances requiring fire-extinguishing protection and shall discharge to an independent exhaust system . Therefore, D is correct.

The IMC requires access openings for fire dampers to be of a size that allows maintenance and resetting of the damper . The code does not set the answer as same-as-duct, half-diagonal, or a universal 12-inch by 12-inch opening. So Option C is correct.

For appliances listed for outdoor installation and incorporating integral venting , the IMC requires them to be installed in accordance with their listings and the manufacturer’s installation instructions . That matches Option C exactly.
