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 73-
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 73 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.
