NORA Study Guide (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 100-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 100 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.
