2. What types of oil should not be used in oil burners according to the
guidelines?
Kerosene and natural gas
Vegetable oil and diesel
Propane and biodiesel
Gasoline and waste crankcase oil
3. If an aquastat fails in an oil burner system, what potential issues could arise in
the heating process?
Increased efficiency of fuel consumption.
Overheating of the water leading to safety hazards.
Reduced maintenance requirements.
Improved combustion quality.
4. What is the primary purpose of fuel-oil systems in buildings?
Water supply
, Heating and energy production
Waste disposal
Electrical generation
5. What is the P-98 Certificate of Fitness (COF) required for?
Installation of electrical systems in buildings.
Operation of natural gas systems in buildings.
Management of hazardous waste in buildings.
Supervision and maintenance of fuel-oil systems in buildings.
6. All fuel is completely burned and no harmful products of incomplete
combustion are produced.
complete combustion
Stoichiometric combustion
incomplete combustion
7. Describe the significance of proper combustion in an oil burner system.
Proper combustion ensures efficient energy production and
minimizes safety hazards.
Proper combustion increases fuel consumption.
Proper combustion only affects the appearance of the system.
Proper combustion is irrelevant to energy production.
8. What is the function of a back pressure relief valve in an oil circulation
system?
To control the temperature of the oil.
, To prevent excessive pressure buildup in the system.
To filter impurities from the oil.
To regulate the flow of oil to the burner.
9. What is the definition of combustion as it relates to oil burner systems?
The process of filtering oil to remove impurities.
The chemical process of burning fuel to produce heat and energy.
The technique of monitoring fuel levels in a system.
The method of storing fuel oil in tanks.
10. What is the result of oil spray burning in suspension within a combustion
chamber?
It reduces emissions.
It leads to incomplete combustion.
It produces excessive soot.
It increases energy efficiency.
11. What is the main role of an oil burner in fuel-oil systems?
To filter impurities from the fuel oil.
To regulate the temperature of the building.
To store fuel oil safely.
To facilitate the combustion of fuel oil.
12. What is the approximate amount of air required for oil burners per gallon of
oil consumed?
, 25 to 30 cubic feet
5 to 10 cubic feet
15 to 20 cubic feet
10 to 15 cubic feet
13. Describe the significance of the P-98 Certificate of Fitness in relation to fuel-
oil systems in buildings.
The P-98 Certificate of Fitness ensures that fuel-oil systems are
supervised by qualified personnel to maintain safety and
compliance.
The P-98 Certificate of Fitness allows for untrained personnel to
operate fuel-oil systems.
The P-98 Certificate of Fitness is only required for gas systems, not oil
systems.
The P-98 Certificate of Fitness is a certification for building aesthetics.
14. In order for oil to burn properly it must:
Be at the proper temperature
Be atomized properly
Have sufficient air to support combustion
All of the above
15. If an oil burner system is experiencing frequent leaks from the oil pump shaft
bearing seals, what maintenance action should be prioritized to ensure
safety and efficiency?
Inspect and replace the seals
Reduce the frequency of maintenance checks
