질문 # 32
Unless listed for a greater or smaller dimension, mechanical draft venting systems shall terminate a minimum of _____ feet below an openable window.
정답:A
설명:
For mechanical draft venting systems, unless the appliance is listed for a different clearance, the vent terminal must be located not less than 4 feet below , 4 feet horizontally from , or 1 foot above any door, operable window, or gravity air inlet into a building. Therefore, the required minimum distance below an openable window is 4 feet , so Option B is correct.
질문 # 33
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.
정답:C
설명:
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
질문 # 34
To test for tightness, a consumer's gas piping should never be filled with:
정답:C
설명:
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.
질문 # 35
Ducts shall not be permitted to be connected to:
정답:B
설명:
The IMC appliance provisions prohibit duct connection to a vented wall furnace . That makes Option B correct. The exam tests recognition of appliance-specific distribution restrictions rather than general duct rules.
질문 # 36
A cooling system with a condensate disposal system:
정답:A
설명:
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.
질문 # 37
