NEW QUESTION # 45
To test for tightness, a consumer's gas piping should never be filled with:
Answer: B
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 # 46
Exhibit:
What hp is EF-2?
Answer: A
Explanation:
Based on the equipment schedule shown in the exhibit, EF-2 is listed with a motor size of 1.5 horsepower .
Therefore, the correct answer is C .
NEW QUESTION # 47
Which of the following is not a required mechanical inspection?
Answer: B
Explanation:
The ICC mechanical administrative inspection sequence includes underground inspection , rough-in inspection , and final inspection as required inspections. An annual system test is not listed as one of the required permit inspections in that section, so Option D is the correct answer. This fits the M2 General Administration content area, which includes permit and inspection administration.
NEW QUESTION # 48
A cooling system with a condensate disposal system:
Answer: C
Explanation:
The ICC mechanical code requires condensate disposal components to be of approved corrosion-resistant material , and the drain line shall not decrease in size from the drain pan connection to the place of disposal.
The code minimum size is 3/4 inch , so the 1/2-inch statement is incorrect, and the code is not limited to PVC only. Also, the slope requirement for horizontal drain piping is not less than 1/8 inch per foot , not 1/4 inch per foot. That makes Option A the only fully correct statement.
NEW QUESTION # 49
Given: The listed clearance is 12 inches.
What would be the reduced clearance to combustibles, in inches, if the millboard is replaced with 24-gauge sheet metal?
Answer: C
Explanation:
For a clearance-reduction system using 24-gauge sheet metal with a ventilated 1-inch air space , the recognized reduction method brings a 12-inch listed clearance down to 4 inches . That matches Option B .
This is also consistent with the protection method shown in the exhibit.
