NORA Bronze (Latest 2026/2027 Update)
Questions and Verified Answers | 100%
Correct | Grade A
The National Oilheat Research Alliance (NORA) Bronze certification exam is an entry-level
test assessing fundamental knowledge of oil heating systems, electricity, and safety. This
143-question set and study guide focus heavily on operating pressures, burner components
(e.g., cad cells), combustion basics, and lockout/tagout procedures.
Core Exam Concepts
This Study set with 143 questions typically cover the essential technical and safety standards
required for HVAC and liquid fuel technicians.
Sample
Operating Pressures: Most modern residential oil burners operate between 100 psi and
140 psi.
Flame Monitoring: The cad cell monitors flame presence and shuts the burner off safely
if no light is detected.
Fuel Efficiency: No. 2 fuel oil is the most common residential fuel, generating roughly
140,000 BTU per gallon.
Troubleshooting: Delayed ignition and rumbling are frequently caused by a dirty nozzle
or poor atomization.
Electrical Safety: Lockout/tagout (LOTO) procedures are strictly tested to ensure
equipment is fully de-energized prior to maintenance.
Quiz_________________?
What does ASTM stand for & what do they publish? -
Answer
American Society for Testing & Materials. ASTM publishes industry specifications
for many different materials including petroleum products. The specification for
Fuel Oils is ASTM D396. This standard sets the minimum specifications for the
fuel.

, Quiz_________________?
The definition of (flash point of a fuel) is what? -
Answer
The maximum temperature at which it can be
safely stored and handled without serious fire
hazard (~100 F)
Quiz_________________?
The definition of (ignition point) is what? -
Answer
The lowest temperature at which rapid
combustion of the fuel takes place in air (~500 F)
Quiz_________________?
The definition of (pour point of #2 oil) is what? -
Answer
The lowest temperature at which oil will flow (21 F)
Quiz_________________?
The pour point of #2 oil can be lowered by what two
2
,methods? -
Answer
It can be lowered by blending with kerosene. It can be lowered with fuel additives
(~1 F)
Quiz_________________?
The viscosity is the thickness of the fuel; viscosity will change depending on the
temperature, as oil gets colder does the viscosity increase or decrease? -
Answer
Increases
Quiz_________________?
One gallon of heating oil contains how many BTU's? -
Answer
139,000 BTU's
Quiz_________________?
Water in the bottom of the tank will lead to what two things? -
Answer
Sludge and ice
3
, Quiz_________________?
Ultra Low Sulfur Fuel (ULSD), all but eliminates what? -
Answer
Scale and soot formation on the heat exchanger surfaces.
Quiz_________________?
Why is #2 Heating Oil Dyed Red? -
Answer
#2 fuel used for heating and hot water purposes is
dyed red to differentiate it from on-road diesel
fuel for tax compliance reasons.
Quiz_________________?
Does evidence of the red dye on components
indicate there's a problem? -
Answer
No, problems with the fuel are not indicated by
the darkness of the color.
Quiz_________________?
Sludge is a combination of what three things? -
Answer
4
