  • 2. 

    (601) When does the heater control unit (HCU) on the New Generation Heater start the main air fan for output air?

    • When a heat setting is selected.

    • Once constant flame is established.

    • When the temperature gauge reads COOL.

    • When the inside temperature reaches 140 degrees F.

    Correct Answer
    A. When the inside temperature reaches 140 degrees F.
    Explanation
    The heater control unit (HCU) on the New Generation Heater starts the main air fan for output air when the inside temperature reaches 140 degrees F. This indicates that the heater has reached the desired temperature and is ready to distribute warm air. The other options, such as when a heat setting is selected, once constant flame is established, or when the temperature gauge reads COOL, do not accurately reflect the trigger for starting the main air fan.

    (602) When should you use starting aids to start the New Generation Heater?

    • Never

    • Occasionally

    • When the temperature gauge reads COOL.

    • When ambient temperature is below 32 degrees F.

    Correct Answer
    A. Never
    Explanation
    Starting aids should never be used to start the New Generation Heater. This implies that the heater is designed to start without any external assistance, such as starting aids. Therefore, it is not necessary to use starting aids for this particular heater model.

    (604) THE FIRST STEP OF TROUBLESHOOTING HEATER EQUIPMENT IS

    • ANALYSIS

    • ISOLATION

    • RECOGNITION

    • VERIFICATION

    Correct Answer
    A. RECOGNITION
    Explanation
    The first step of troubleshooting heater equipment is recognition. This involves identifying and acknowledging that there is a problem with the equipment. It is important to recognize the signs or symptoms of the issue in order to proceed with the troubleshooting process effectively. Once the problem is recognized, further steps can be taken to isolate, analyze, and verify the cause of the problem.

    (603) THE TYPE OF INSPECTION THAT REQUIRES THE MOST TEAR DOWN OF SPECIFIC COMPONENTS IS THE

    • DAILY INSPECTION.

    • SERVICE INSPECTION.

    • SPECIAL INSPECTION.

    • PERIODIC INSPECTION.

    Correct Answer
    A. SPECIAL INSPECTION.
    Explanation
    The correct answer is SPECIAL INSPECTION. Special inspections typically involve a more thorough examination of specific components or systems, which may require disassembling or tearing down certain parts. This type of inspection is usually conducted for specific purposes such as troubleshooting, evaluating the condition of critical components, or ensuring compliance with regulatory standards. Daily inspections, service inspections, and periodic inspections are generally less extensive and may not involve as much teardown of specific components.

    Rate this question:

  • 6. 

    (601) What component on the New Generation Heater activates the heat control unit (HCU)?

    • Heat control switch

    • Burner control unit

    • Thermostatic sensor

    • Oil pressure switch

    Correct Answer
    A. Heat control switch
    Explanation
    The heat control switch is the component on the New Generation Heater that activates the heat control unit (HCU). This switch allows the user to adjust the desired temperature and turns on the HCU, which then controls the operation of the heater to maintain the set temperature. The burner control unit, thermostatic sensor, and oil pressure switch are not responsible for activating the HCU.

  • 7. 

    (605) HEAT THAT CAN BE FELT, AND ADDED OR SUBTRACTED TO A SUBSTANCE WITHOUT CHANGING ITS STATE IS CALLED

    • SUPER HEAT

    • LATENT HEAT

    • SPECIFIC HEAT

    • SENSIBLE HEAT

    Correct Answer
    A. SENSIBLE HEAT
    Explanation
    Sensible heat is the correct answer because it refers to the heat that can be felt and added or subtracted to a substance without changing its state. Unlike latent heat, which is associated with phase changes, sensible heat is related to changes in temperature. Specific heat, on the other hand, is the amount of heat required to raise the temperature of a substance by a certain amount, while superheat refers to the heat added to a substance above its boiling point. Therefore, sensible heat is the most appropriate term for the given description.

  • 8. 

    (603) IF YOU NEET TO FIND OUT HOW TO PERFORM ANY MAINTENANCE REQUIRED DURING AN INSPECTION, YOU SHOULD REFER TO THE

    • -1 TO

    • PE WORKCARDS.

    • METHODS AND PROCEDURES TO.

    • SERVICE INSPECTION WORKCARDS.

    Correct Answer
    A. -1 TO
    Explanation
    The correct answer is -1 TO PE WORKCARDS. This answer suggests that if you need to find out how to perform any maintenance required during an inspection, you should refer to the PE workcards. The PE workcards likely contain detailed instructions and procedures for carrying out maintenance tasks during an inspection.

    Rate this question:

  • 9. 

    (602) WHEN OPERATING THE NEW GENERATION HEATER, TURN THE HEAT CONTROL SWITCH TO THE DESIRED POSITION AFTER

    • AMPLE WARM-UP TIME.

    • A MINIMUM OF 45 SECONDS.

    • SYSTEM VOLTAGE RISES TO 120 VAC.

    • THE INSIDE TEMPERATURE REACHES 140 DEGREES

    Correct Answer
    A. SYSTEM VOLTAGE RISES TO 120 VAC.
  • 10. 

    (605) THE AMOUNT OF HEAT REQUIRED TO RAISE THE TEMPERATURE OF ONE POUND OF A SUBSTANCE ONE DEGREE FAHRENHEIT IS KNOW AS

    • SUPER HEAT

    • LATENT HEAT

    • SPECIFIC HEAT

    • SENSIBLE HEAT

    Correct Answer
    A. SPECIFIC HEAT
    Explanation
    The correct answer is SPECIFIC HEAT. Specific heat refers to the amount of heat energy required to raise the temperature of a given substance by one degree Fahrenheit. It is a property that is unique to each substance and is used to calculate the amount of heat transferred during a temperature change.

    Rate this question:

  • 11. 

    (605) THE HEAT THAT CHANGES THE STATE OF A SUBSTANCE, YET DOES NOT AFFECT THE TEMPERATURE IS CALLED

    • SUPER HEAT

    • LATENT HEAT

    • SPECIFIC HEAT

    • SENSIBLE HEAT

    Correct Answer
    A. SUPER HEAT
    Explanation
    Superheat is the correct answer because it refers to the heat that changes the state of a substance without affecting its temperature. This occurs when a substance is heated above its boiling point, causing it to transition from a liquid to a gas state. The additional heat added during this process is known as superheat.
