2026/2027 OIL BURNER PRACTICE
EXAM WITH 68 QUESTIONS AND
CORRECT ANSWERS RATED +
A fuel oil storage tank cannot be installed:
In the furnace room within 5 feet of the heating unit
the primary purpose of a fuel pump on a high pressure burner is to:
-Deliver oil at a constant and regulated pressure to the nozzle
-Move oil from the tank to the pump
-Provide a screen to filter the oil
If the vacuum reading is substantially above the calculated reading, (with the
burner running) the cause may be:
All of the above - plugged fuel filter, kinked oil supply line, check valve sticking
With most new flame retention burners, the motor speed is:
3450 rpm
To check for a proper nozzle line cut-off, the pressure gauge is installed in the:
Nozzle port
Fuel units are generally set at the factory at:
100 psi
the oil burner nozzle in a high pressure burner performs the following functions:
All of the above - atomizes the oil, provides a pattern of oil spray, delivers a fixed
amount of oil
the nozzle flow rate, spray angle and pattern are directly related to:
All of the above - tangential slots, swirl chamber, orifice
Cold oil or high viscosity problems may be eliminated by:
, A & B - increasing pump pressure and reducing nozzle size & installing a nozzle
line pre-heater
the following conditions or elements affect choosing the correct nozzle spray
patterns:
A&B - Air-oil mixing design of the burner & Shape of the chamber
which condition affects nozzle spray droplet size?
Fuel pump pressure
Ignitors are better than ignition transformers because:
They have higher output voltage and use less electricity than transformers
All Pressure tests on an oil pump must be taken at the nozzle port.
False
Any valve used on an oil burner installation must be a:
fusible valve
The hot water temperature control is low voltage operating control as is the
thermostat and is wired to the primary control in parallel with the thermostat.
false
A thermostat is located near a lamp. What effect if any would this have on the
heating system?
It would cause occasional erratic insufficient heat
A clear piece of plastic tubing is put into the supply line to view:
both a&c - The color and quality of the oil & air bubbles in the system
True or False: A masonry chimney needs an approved or listed liner.
true
Oil burning appliances shall have:
all of the above - automatic limit control to prevent over pressure in a steam
boiler, high temperature in a water boiler, and high temperature in a furnace
