70% to passWhich of the following labeled items of the illustrated air register and burner assembly represents the mechanism for operating the register air doors? Illustration SG-0016
A2
B4
C6
D12
AI Explanation
The correct answer is D) 12. The mechanism for operating the register air doors is represented by item 12 in the illustrated air register and burner assembly (Illustration SG-0016). This is the air register damper, which controls the amount of air flowing through the register and into the space being heated. The other answer choices are incorrect because they represent different components of the assembly, such as the air register (2), the primary air inlet (4), and the burner assembly (6), but do not specifically depict the mechanism for operating the air register doors.
