質問 # 40
The minimum dimension for rectangular air ducts used to supply combustion air for natural draft systems is
_____ inches.
正解：B
解説：
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.
質問 # 41
Given: A recirculating industrial direct-fired makeup air heater has a rated input of 200,000 Btu/h .
Ventilation air is supplied by separate mechanical means.
Outside ventilation air shall be provided to supply at least _____ CFM.
正解：A
解説：
The applicable provision requires direct-fired industrial air heaters to supply outside ventilation air at a rate of not less than 4 cfm per 1,000 Btu/h of rated input where ventilation air is provided by separate mechanical means. For 200,000 Btu/h , the required outside air is:
200,000 ÷ 1,000 = 200
200 × 4 = 800 cfm
So the correct answer is C
質問 # 42
Supports for hazardous exhaust duct shall be constructed of:
正解：B
解説：
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.
質問 # 43
Shutoff valves in plastic pipe ground-source heat pump loop systems shall be installed on both sides of which one of the following?
正解：A
解説：
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.
質問 # 44
Termination of vents for appliances listed for and installed outdoors that incorporate integral venting shall:
正解：C
解説：
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.
