International Code Council Commercial Mechanical Inspector Sample Questions (Q46-Q51):

NEW QUESTION # 46
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 # 47
Exhaust outlets that terminate at a temperature exceeding 600°F shall be designed as a:

Answer: B

Explanation:
ICC clearance-reduction tables allow a listed clearance of 18 inches to be reduced to 9 inches where 24- gauge sheet metal is installed with a 1-inch ventilated airspace from the combustible wall. Therefore the correct answer is the option corresponding to 9 inches , which is B in your set.
