controls, safety devices, venting, troubleshooting, code compliance, and professional
judgment. It targets experienced installers and candidates seeking Class A or Class B
licensing who need to apply technical requirements to realistic field conditions. The
examination contains 150+ questions and answers with a rationale, emphasizing
difficult scenario-based decisions rather than simple memorization. Students should
expect complex installation, diagnostic, regulatory, safety, and commissioning
situations. (purchase and instantly get a downloadable and editable pdf)
QUESTIONS 1–150
Question 1
,A Class B Oil Burner Equipment Installer is assigned a project involving an oil-burning
appliance using No. 6 fuel oil. What is the most appropriate licensing conclusion?
A. The installer may perform the work because all oil burners are within Class B scope.
B. The installer may perform the work only if the appliance input is below 500,000 Btu/h.
C. The work exceeds the ordinary Class B scope because Class B is limited to domestic-
grade No. 1 through No. 4 fuel oils.
D. The installer may perform the work if supervised by any licensed plumber.
Correct Answer: C
Explanation: Class B licensing is limited to oil-burning equipment using domestic-
grade fuel oils No. 1 through No. 4; broader oil-burning work falls within Class A
scope.
Question 2
A candidate passed the NYC Oil Burner Equipment Installer written examination but
delays taking the practical examination. Which statement best reflects the licensing
requirement?
A. The practical examination may be delayed indefinitely.
B. The candidate generally has 24 months from notification of passing the written
examination to pass the practical examination.
C. The candidate has 36 months from application.
D. The candidate must retake the written examination after 12 months.
Correct Answer: B
Explanation: The applicable licensing rule provides a 24-month period from
notification of passing the written examination to pass the practical examination.
Question 3
During an installation, the manufacturer's instructions conflict with an installer’s
preferred field practice. What should govern the installation?
A. The installer's customary practice
B. The lowest-cost installation method
C. The manufacturer's listing and installation requirements together with applicable NYC
codes
D. The customer's preferred arrangement
, Correct Answer: C
Explanation: Listed equipment must be installed according to applicable construction
codes and the manufacturer's instructions; personal preference cannot override those
requirements.
Question 4
An installer discovers that an existing burner has been modified in a manner not
authorized by its listing. What is the most defensible action?
A. Continue operating it if combustion appears acceptable
B. Restore the equipment to an approved configuration before relying on its safety or
performance
C. Increase the fuel pressure to compensate
D. Disable the affected safety control
Correct Answer: B
Explanation: Unauthorized modifications can invalidate listing assumptions and safety
performance; the equipment should be restored or replaced with an approved
configuration.
Question 5
A Class A installer is evaluating a system using No. 6 fuel oil. Which additional
consideration is especially important compared with a lighter domestic-grade fuel
system?
A. No combustion air is required.
B. Fuel conditioning, heating, pumping, and viscosity control may be required for proper
atomization.
C. The burner cannot have flame safeguard controls.
D. The system must use only gravity feed.
Correct Answer: B
Explanation: Heavy fuel oils have significantly higher viscosity and may require
heating and conditioning to achieve proper flow and atomization.
Question 6
A technician proposes using gasoline as an emergency substitute for fuel oil because
the burner has run out of oil. What is the correct response?
, A. Acceptable if mixed with No. 2 oil
B. Acceptable only at low firing rates
C. Prohibited; gasoline is not an acceptable substitute fuel for an oil burner
D. Acceptable if the nozzle is changed
Correct Answer: C
Explanation: Gasoline presents severe fire and vapor hazards and is not an approved
substitute for burner fuel oil.
Question 7
An oil burner is listed for a particular fuel grade, but the building owner requests
another grade because it is cheaper. What should the installer do?
A. Use the cheaper fuel if the burner starts.
B. Use the alternative only during commissioning.
C. Verify that the burner is approved for the proposed fuel before use.
D. Dilute the fuel with gasoline.
Correct Answer: C
Explanation: The fuel must be compatible with the burner listing, manufacturer
requirements, and applicable code requirements.
Question 8
A practical examination candidate is asked to diagnose a burner that repeatedly locks
out after ignition. What should be done first?
A. Replace the fuel pump immediately.
B. Disable the primary control.
C. Observe and analyze the operating sequence before replacing components.
D. Increase firing rate.
Correct Answer: C
Explanation: Systematic diagnosis begins by identifying where the normal operating
sequence fails rather than replacing components without evidence.
Question 9
Which diagnostic approach best demonstrates professional troubleshooting?
