1. The cross connection between two supply tanks shall not exceed?:
| | | | | | | | |
660gallons
| |
2. When is an automatic draft control not required?: When the equipment | | | | | | | | | |
isdesigned to control the draft.
| | | | | |
3. Combustion performance testing can indicate:: Improper air oil mixture, | | | | | | | |
toomuch combustion air, and low pump pressure.
| | | | | | | |
4. If a second oil-burning appliance is installed in a single chimney, you
| | | | | | | | | | |
mustinsure:: Sufficient draft is available for safe operation of all connected
| | | | | | | | | | | |
equipment.
|
5. Delayed ignition can be caused by:: Weak ignition transformer | | | | | | | |
6. You should replace the oil burner nozzle with:: The manufacturers recom-
| | | | | | | | | |
mended nozzle spray pattern and spray angle.
| | | | | | |
7. Viscosity problems can be corrected by:: Decreasing the nozzle size | | | | | | | | |
andincreasing the pump pressure accordingly
| | | | | |
8. The minimum operating pressure of an oil pump is:: 100 PSI
| | | | | | | | | |
9. If a stack relay fails you, must?: Replace it with an approved type controller
| | | | | | | | | | | | |
10. Aquastats are normally found on what type of heating systems?: Hydronic | | | | | | | | | |
11. Airstats are found on what type of heating systems?: Forced warm | | | | | | | | | |
airsystems
| |
12. Under sized returns on a warm air system can result in what?: Short cyclingof | | | | | | | | | | | | | |
the oil burner
| | |
13. Incorrect nozzle selection in regards to gallon per hour, can result in | | | | | | | | | | |
whatproblems in a steam system?: Some radiators not heating quickly enough
| | | | | | | | | | | |
14. Low boiler water temperature in a hydronic hot water system may | | | | | | | | | |
becaused by?: Undersized oil burner nozzles
| | | | | | |
15. Delayed opening oil valves are used to?: Allow oil pump to come up to speed | | | | | | | | | | | | | |
16. If a steam boiler is to be installed with an automatic feeder it must
| | | | | | | | | | | | |
alsohave:: A backflow prevention device
| | | | | |
17. How can a damaged heat exchanger be detected on a forced warm | | | | | | | | | | |
airsystem?: With a smoke trace candle
| | | | | | |
18. If a high limit is installed to prevent high boiler water temperature, what isthe
| | | | | | | | | | | | | |
function of the low limit?: To maintain temperature for domestic hot water
| | | | | | | | | | | |
19. On a steam system, a plugged siphon loop can have what affect on
| | | | | | | | | | | |
theheating system?: Insufficient heat in the living space
| | | | | | | | |
20. On a triple acting aquastat a minimum of 20 degrees is recommend be-
| | | | | | | | | | | |
tween the high and low limit, this will prevent?: The boiler going off on high
| | | | | | | | | | | | | | |
limitbefore reaching the minimum circulator temperature
| | | | | | |
21. An advantage of flame retention burner is: Their high static pressure
| | | | | | | | | |
enablesboilers and furnaces with tighter more efficient heat exchange passages
| | | | | | | | | | |
22. The key final adjustment for most oil burners is: Combustion air| | | | | | | | | |
