NEW QUESTION # 26
To test for tightness, a consumer's gas piping should never be filled with:
Answer: C
Explanation:
The IFGC section on test medium states that the test medium shall be air, nitrogen, carbon dioxide or an inert gas , and specifically states that oxygen shall not be used as a test medium . That makes C the correct answer.
NEW QUESTION # 27
Pipe and duct insulation can be used within plenums except:
Answer: C
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 # 28
For gas piping installations, which of the following is an acceptable joining method for polyethylene (PE) pipe?
Answer: B
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
NEW QUESTION # 29
The minimum dimension for rectangular air ducts used to supply combustion air for natural draft systems is
_____ inches.
Answer: B
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 # 30
Where located on a roof with a 5:12 slope, a level platform shall be provided along the access panel of the furnace at least _____ inches wide.
Answer: D
Explanation:
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 .
