Your starting point

How do I prepare for the G2 exam?

To prepare for the G2 exam, review gas code requirements, appliance service logic, venting, piping, controls, safety, and troubleshooting. Use topic practice first, then timed mock exams and careful review of missed questions.

For G2 exam prep, combine official G2 modules, CSA B149.1 codebook practice, appliance troubleshooting review, and timed mock exams. CodeSafe Academy supports this with G2-specific practice, explanations, progress tracking, and weak-area review.

How to prepare

  • Review your official G2 modules, classroom notes, appliance service procedures, installation requirements, and safety responsibilities.

  • Practise troubleshooting logic for controls, burners, ignition sequence, safeties, electrical faults, and field diagnostic wording.
