M2 Exam Dumps - International Code Council Commercial Inspector Questions and Answers

The IMC prohibits energy recovery ventilation systems in several applications, including hazardous exhaust systems , smoke control systems , commercial kitchen exhaust systems , and clothes dryer exhaust systems . Equipment intended to assist with occupant evacuation falls under smoke-control/life-safety type applications and is not an allowed ERV use. By contrast, systems utilizing coil-type exchangers are the exception among the listed choices because they are not one of the prohibited applications in this question. Therefore, Option A is correct.

The IMC states that solar thermal equipment exposed to vehicular traffic must be installed not less than 6 feet above the finished floor . It then gives an exception stating that this requirement does not apply where the equipment is protected from motor vehicle impact . Because the height requirement is removed by that exception, the best answer from the choices given is A, directly on finished floor . This is an inference from the exception language.

For appliances on roofs, ICC access provisions require a level platform at the appliance. The platform must be not less than 30 inches in any dimension . For the choices provided, that makes 30 inches the correct answer, which is Option C .

Under the IMC ventilation table, locker/dressing rooms and sports locker rooms are identified with required mechanical exhaust, while spaces such as guard stations do not carry that same exhaust requirement in the table. A high school locker room falls within the locker-room/sports-locker-room category, so Option C is the correct answer. Gambling casinos and office break rooms are provided outdoor air rates, but they are not the required-exhaust space among these listed choices.

The ICC mechanical code requires the lowest portion of a floor furnace to have not less than 6 inches (152 mm) clearance from grade level . Therefore, the correct choice is the option corresponding to 6 inches , which is C based on your answer set.

This is also an exhibit-reading question. From the equipment schedule in the image, CEF-5 is listed as a Nutone unit, so Option D is correct. This falls under reading commercial mechanical drawings and equipment schedules related to exhaust/ventilation components.

The IFGC requires the appliance shutoff valve to be located in the same room as the appliance and within 6 feet of the appliance . Therefore, the correct answer is A .

The IMC special exhaust provisions require exhaust outlets terminating at temperatures exceeding 600°F to be designed as a chimney , and the table language identifies this as a single-wall metal chimney . Therefore, Option D is correct.

In the IMC hydronic piping provisions for ground-source heat pump loop systems, shutoff valves are required on both sides of a pressure-reducing valve . That matches D . Heat-fusion joints and change-in-material joints do not trigger this two-sided shutoff-valve requirement.

Vent connectors must be installed with a minimum rise of 1/4 inch per foot . For a 10-foot run, the required rise is:

10 × 1/4 inch = 2.5 inches .

That equals 2-1/2 inches , so Option D is correct.
