1. In a typical oil burner, the motor drives: Both the fuel unit and the
fan
2. The key final adjustment for most oil burners is: Combustion air
3. High static air pressure burners: Enable boilers and fur-
naces to have tighter more
efficient heat exchanger
passages
4. Dirt or lint build-up on the burnerfan blades will: Reduce the amount of
combustion air
5. One gallon of #2 oil contains approximately: 140,000 BTU's
6. All petroleum products are chemical compounds of: Hydrogen and Carbon
7. The pour point of #2 oil is: The lowest temperature at
which oil will flow
8. Flash point of a fuel is an indication of: The maximum tempera-
ture at which it can be
safely stored and handled
without serious fire hazard
9. The pour point of #2 oil can be reduced by: Blending it with kerosene
10. As heating oil gets colder its viscosity (thickness): Increases
11. A tank without a vent alarm: Should not be filled
12. Oil lines that contact concrete or dirt should be: Coated or sleeved in plas-
tic pipe with no fittings be-
low the floor

13. What is the most common source of water in oil tanks? Condensation
14. The home for bacterial growth and sludge in the bot- Water
tom of the oil tank is:
15. Pumping the old oil from a tank being replaced into Must be avoided because
the new tank: it can lead to premature
tank failure
16. Fuel units perform the following functions: Move oil from the tank to
the burner and deliver it at
a constant regulated pres-
sure to the nozzle
17. The best way to clear a clogged oil line is to: Use a hand pump to suck
the blockage out
18. If the oil level in the tank is 4 feet below and 10 feet 4 to 7 inches
away from the fuel unit and the oil filter is clean the
vacuum reading should be approximately:
19. If the operating vacuum is significantly less than the A suction line leak
calculated vacuum you probably have:
20. If the operating vacuum reading is significantly above A clogged oil filter
the calculated vacuum you probably have:
21. It is best to connect fuel units as a one-pipe system One pipe leads to longer
instead of two-pipe because: filter life and eliminates
worries about leaking re-
turn lines
22. If a nozzle is dirty or plugged it should be: Replaced

23. What keeps a nozzle from overheating while the burn- The amount of air and oil
er is running? traveling past it
24. The flow rate stamped on the nozzle is based on: 100 psi
25. The purpose of an oil burner nozzle is to: Atomize and meter the oil
26. Nozzle after-drip can be caused by: Thermal expansion of the
oil in the drawer assembly
after shut down
27. To reduce combustion problems caused by cold oil: Increase the pump pres-
sure and reduce the nozzle
size
28. Increasing the fuel pump pressure will: Increase the flow rate
29. Generally, the end of the burner air tube should be: Be flush with the face of
the chamber or recessed
approximately ¼"
30. The draft regulator can: Decrease the draft
31. A draft regulator is required because: The draft produced by the
chimney needs to be con-
trolled
32. The most important draft measurement is: Over the fire
33. To get accurate results, a combustion test should be When the unit reaches
performed: steady state operation
34. Excessive draft drop through the heat exchanger indi-
