International Code Council Commercial Mechanical Inspector Sample Questions (Q22-Q27):

NEW QUESTION # 22
What is the minimum air velocity that must be provided by an exhaust duct system serving a Type I range hood?

Answer: C

Explanation:
For commercial kitchen exhaust associated with Type I hood systems, the recognized code-based minimum duct transport velocity is 1,500 feet per minute , so C is the correct answer. Option B uses the wrong unit, and the other listed velocities do not match the code minimum used for this question type.


NEW QUESTION # 23
Supports for hazardous exhaust duct shall be constructed of:

Answer: C

Explanation:
Hazardous exhaust systems are regulated under the IMC provisions for special exhaust because they handle potentially dangerous fumes, vapors, dusts, or other contaminants. The code requires the duct system and its support components to be suitable for that hazard level, and supports for hazardous exhaust duct must be constructed of noncombustible material . That is why Option C is correct. Plastic and fibrous supports would not satisfy the required fire and safety performance, and UL 181 applies to certain factory-made air ducts and connectors, not as the governing support-material rule for hazardous exhaust duct supports.


NEW QUESTION # 24
An 8-inch Type B venting system with a listed vent cap must terminate a minimum of _____ feet above the flat roof through which it passes.

Answer: B

Explanation:
For a Type B gas vent with a listed vent cap terminating through a flat roof , the minimum required termination height is 1 foot above the roof . That makes Option A correct. This is consistent with gas vent termination tables used with listed Type B vent systems and the code framework for Type B vent terminations.


NEW QUESTION # 25
The minimum dimension for rectangular air ducts used to supply combustion air for natural draft systems is
_____ inches.

Answer: D

Explanation:
The IMC combustion-air provisions require openings used for combustion air to have a minimum cross- sectional dimension of 3 inches . Where ducts are used, they must be of the same cross-sectional area as the openings to which they connect. That makes 3 inches the correct answer, so Option B is correct.


NEW QUESTION # 26
What is the minimum distance required between a combustion air opening at the exterior of a building and a lot line?

Answer: B

Explanation:
The ICC opening-location rule requires intake openings to be located not less than 10 feet from lot lines or buildings on the same lot . A combustion-air opening taken from the exterior follows that minimum separation rule, so 10 feet is the correct answer. Therefore, Option D is correct.
