NEW QUESTION # 31
Pipe and duct insulation can be used within plenums except:
- A. where the assembly has been tested to UL 723.
- B. where the assembly has been tested to ASTM B84.
- C. where the assembly has been tested to ASTM E84.
- D. where the flame spread index is not more than 25.
Answer: B
Explanation:
For materials such as pipe and duct insulation within plenums, the IMC references ASTM E84 or UL 723 for surface-burning characteristics, along with the flame-spread and smoke-developed limits applicable to plenums. ASTM B84 is not the referenced plenum test standard here, so it is the incorrect condition and therefore the correct exam answer to the "except" question. This makes Option C correct.
NEW QUESTION # 32
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.
- A. 0
- B. 1
- C. 2
- D. 3
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 # 33
Exhibit:
CEF-5 is a ceiling exhaust fan manufactured by:
- A. Carnes
- B. Markel
- C. G.E.
- D. Nutone
Answer: D
Explanation:
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.
NEW QUESTION # 34
For the installation of listed fuel-burning appliances, the required clearances should be found:
- A. in the mechanical code.
- B. on the nameplate of the appliance.
- C. on the approved plans and specifications for the building.
- D. by using a calculation based on the Btu/h output rating of the appliance.
Answer: B
Explanation:
The IMC requires fuel-burning units to be marked with the hourly rating, approved fuel type, and required clearances . That means the appliance marking/nameplate is the direct source for the required clearance information for listed fuel-burning appliances. This is why B is the correct answer.
NEW QUESTION # 35
The minimum rise required for a 10-foot run of vent connector is _____ inches.
- A. 1-1/4
- B. 2-1/2
- C. 0
- D. 1-1/2
Answer: B
Explanation:
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.
NEW QUESTION # 36
Supports for hazardous exhaust duct shall be constructed of:
- A. fibrous material.
- B. material complying with UL 181.
- C. noncombustible material.
- D. plastic.
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 # 37
What type of cooking appliance is required to have its own independent hood and exhaust system?
- A. Extra-heavy-duty
- B. Heavy-duty
- C. Medium-duty
- D. Light-duty
Answer: A
Explanation:
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.
NEW QUESTION # 38
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.
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
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
NEW QUESTION # 39
What is the minimum air velocity that must be provided by an exhaust duct system serving a Type I range hood?
- A. 500 CFM
- B. 500 FPM
- C. 1,500 FPM
- D. 2,500 FPM
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 # 40
ERV systems shall not be installed in which of the following except:
- A. systems utilizing coil-type exchangers.
- B. common exhaust systems for clothes dryers.
- C. equipment designed to assist in the evacuation of occupants.
- D. exhaust systems emitting corrosive materials.
Answer: A
Explanation:
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.
NEW QUESTION # 41
Why are two or more sets of construction documents, engineering calculations, diagrams, and other data required to be submitted with each application for a permit?
- A. All sets of documents are to be kept by the code official, and at least one set will serve as a backup set of documents in case the other is lost or misplaced.
- B. To ensure that the project is completed in a timely manner.
- C. One set will be retained by the code official, and the other will be returned to the applicant and kept on the job site for reference while construction is in progress.
- D. All sets are to be retained by the code official in order to have a spare set of construction documents for use by any subcontractors.
Answer: C
Explanation:
The ICC administrative provisions require construction documents to be submitted in two or more sets with the permit application. After approval, one set is retained by the code official and one set is returned to the applicant to be kept on the job site during construction. That is exactly the condition described in Option D .
The code does not state that all sets are retained by the code official or that the purpose is to provide subcontractor copies or backup copies.
NEW QUESTION # 42
Natural, manufactured and liquefied petroleum, or a mixture of these, make up:
- A. natural gas.
- B. fuel oil.
- C. fuel gas.

This is also consistent with the protection method shown in the exhibit.
NEW QUESTION # 47
When a furnace is installed in a 66-inch-high attic, the maximum distance from the passageway access to the furnace shall be _____ ft., measured along the centerline of the passageway.
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
ICC mechanical access provisions for appliances in attics require the passageway to be not more than 20 feet in length , measured along the centerline of the passageway from the opening to the appliance, where the attic passageway is the standard reduced-height access condition. Since the attic height given is 66 inches, the standard maximum length applies, so Option C is correct. The 50-foot allowance applies only under a different exception where the passageway is unobstructed and at least 6 feet high for its entire length.
NEW QUESTION # 48
Indoor combustion air shall be provided within:
- A. 2 feet of the ceiling and 1 foot of the floor.
- B. 1 foot of the ceiling and 1 foot of the floor.
- C. 2 feet of the ceiling and 2 feet of the floor.
- D. 1 foot of the ceiling and 2 feet of the floor.
Answer: B
Explanation:
For indoor combustion air openings, one opening must commence within 12 inches of the top of the enclosure and one within 12 inches of the bottom . That corresponds to 1 foot of the ceiling and 1 foot of the floor , so Option A is correct.
NEW QUESTION # 49
The exhibit shows a _____ in. diameter gas line between unit heaters 5 and 8.
- A. 1-1/4
- B. 1-1/8
- C. 3/4

NEW QUESTION # 50
Air mechanically exhausted from a room must be:
- A. discharged to the outdoors.
- B. recirculated.
- C. discharged into the attic.
- D. filtered.
Answer: A
Explanation:
The IMC requires air removed by a mechanical exhaust system to be discharged outdoors to an approved location and not be readily drawn back into the building. That makes D correct. The code does not permit general exhaust air to terminate in an attic, and it does not make filtering or recirculation the default rule for mechanically exhausted air.
NEW QUESTION # 51
For gas piping installations, which of the following is an acceptable joining method for polyethylene (PE) pipe?
- A. Solvent cement
- B. Threaded coupling
- C. Compression coupling
- D. Rubber cement
Answer: C
Explanation:
This item appears to use older or simplified exam wording . Current ICC language for polyethylene plastic piping identifies heat-fusion joints, electrofusion joints, and stab-type insert fittings as the named PE joining methods, not solvent cement or threaded couplings. Among the answer choices you provided, D.
Compression coupling is the only choice that aligns most closely with a mechanical fitting/joining approach for PE systems, while rubber cement, solvent cement, and threaded coupling do not match ICC PE joining practice. Because of that, D is the best answer from the listed options, but this question should be tied to the exact code cycle or source exam bank if you want absolute cycle-specific certainty
