FDNY COF P-98 EXAM QUESTIONS AND
CORRECT ANSWERS
Question 1
63.- Effects of Improper Operation of an Oil Burner System
Blockage in the chimney or flue passage
Correct Answer
Will cause the cellar or boiler room to become filled with smoke.
Question 2
105.- Discharge Pressure Requirements
The pressure required at the discharge of the pump will be the pressure
Correct Answer
Required at the point of use plus the friction losses in the intervening piping
with the installation of a back pressure regulating valve. Pressure and air
atomizing burners may require that relatively high pressure be provided by the
pump set if there is no pump on the burner itself. The valve should be sized so
that the pressure buildup (in the case of a back-pressure valve) or drop (in the
case of a pressure regulator) is small.

,Question 3
5.- Supervision of Fuel-Oil Piping & Storage Operation
Shall be under the GENERAL SUPERVISION of P-98:
Correct Answer
A stationary fuel-oil storage tank, related piping, that is installed on the
lowest floor of the building and transfer fuel-oil through piping to another
stationary fuel-oil storage tank, or fuel burning equipment, installed above
such floor
Question 4
- Oil Burner Controls
The Steam pressure gauge...
Correct Answer
Shows the steam pressure inside the steam boiler. The pressure gauge reads in
psi (pounds per square inch). It is located on or near the top of the steam boiler.
Normal steam pressure for low pressure boilers does not exceed 15 psi. (If the
indicated stream pressure is significantly greater than the normal pressure, the
best action is to shut down the system and call 911 since this is a serious
problem)
Question 5
9.- Licences & Certificates
No oil burning equipment may operated until
Correct Answer
a) Certificate of Compliance has been issued by NYCDOB
b) Air pollution control code requirements NYCDEP
c) Permit for the Storage & use of fuel-oil issued by FDNY

,Question 6
54.- Oil Burner Controls
The Gauge Glass
Correct Answer
Device used to indicate the water level of a steam boiler. It is the most
important control on the steam boiler. Gauge glass should have water visible
when the boiler is in operation.
Question 7
79.- Fuel Tanks, Piping & Valves
The Installation in accordance NYC Construction Codes
Correct Answer
The tank, piping and valves for appliances burning oil must be installed in
accordance with the requirements of the NYC Construction Codes. When oil
burning equipment is served by a tank which is above the level of the burner
inlet connection, and where the fuel supply line is taken from the top of the
tank, an approved anti-siphon valve or other siphon-breaking device must be
located at the highest point in the supply line.
Question 8
28.- Oil Burner Operation
Oil burners required approximately
Correct Answer
2000 cubic feet of air per gallon of oil consumed. The mixture of oil and air is
sprayed in vapor form into a firebox area (the combustion chamber) where
combustion takes place
Page 3 of 99
, Question 9
- Alarms
d) Some pumps are...
Correct Answer
Manually operated while others have intermittent operation. This does not
eliminate the requirement of shutdown interlocks and automatic back up
pump operation for safety purposes. Since each system is unique, the control
strategy will be different from one job to another.
Question 10
36.- Oil Burner Operation
Excessive Air Supply
Correct Answer
Can put out the flame
Question 11
105.- Emergency Vents
The normal and emergency vents are
Correct Answer
Required to be combined. For tanks installed above the lowest floor, such
combined vents must be piped, in an approved manner, into the vent or top of
the tank of the lowest floor storage tank that supplies fuel to the tank.
Question 12
6.- Supervision of Fuel-Oil Piping & Storage Operation Shall be under the PERSONAL
SUPERVISION of P-98 COF
Correct Answer
Periodic Inspection and Testing of tanks and piping
