MASSACHUSETTS OIL BURNER
PRACTICE QUESTIONS ANDSTIONS
AND ANSWERS 100% CORRECT
(GRADED A+)
What is the maximum combined capacity allowed for cross-connected oil
supply tanks?
✔✔ 660 gallons.
When is an automatic draft regulator not required?
✔✔ If the equipment is built to regulate its own draft.
What issues can be identified through combustion testing?
✔✔ Poor air-to-oil ratio, excess combustion air, or low fuel pump pressure.
If two oil appliances share a chimney, what must be ensured?
✔✔ That the chimney provides enough draft for both appliances to operate safely.
What is a common cause of delayed ignition?
✔✔ A weak ignition transformer.
When replacing a burner nozzle, what should you use?
✔✔ The nozzle type, angle, and spray pattern recommended by the manufacturer.
How can you correct viscosity issues in fuel delivery?
✔✔ Reduce the nozzle size and increase the pump pressure accordingly.
, What is the minimum pressure an oil pump must operate at?
✔✔ 100 PSI.
What should you do if a stack relay fails?
✔✔ Replace it with a code-approved controller.
Where are aquastats typically found?
✔✔ In hydronic (hot water) heating systems.
Which systems use airstats?
✔✔ Forced warm air heating systems.
What problem can undersized return ducts cause in warm air systems?
✔✔ Short cycling of the burner due to restricted airflow.
What happens in steam systems if the nozzle GPH is too low?
✔✔ Some radiators may take longer to heat up or remain cold.
What might cause low water temperatures in a hot water boiler?
✔✔ An undersized burner nozzle.
What’s the purpose of a delayed opening oil valve?
✔✔ To allow the oil pump to reach speed before delivering fuel.
What additional device is required if installing an automatic feeder on a steam
boiler?
✔✔ A backflow preventer.
