NSW Gasfitting study plan

Map each domain's weighting to a weekly time budget and write it down as a one-page schedule

Summarise the licensing, notification and record-keeping duties that attach to gasfitting work in NSW into a checklist

Define the combustion equation for natural gas and LPG and calculate theoretical air requirements for three sample inputs

List the AS/NZS standards and regulatory instruments you must be able to locate by name, and note what each covers

Calculate stoichiometric air, excess air and CO2 percentages for at least five worked fuel/air scenarios

Explain how incomplete combustion arises from air deficiency, flame impingement and poor burner condition

Determine ventilation requirements for an enclosed space using appliance input and room volume

Classify the physical properties of natural gas and LPG that drive installation decisions, including relative density and flammability limits

Size gas pipework for three realistic installations using pressure drop and load tables

Draft a pipework layout showing isolation, sleeving, support spacing and clearances to other services

Select flueing arrangements appropriate to appliance type and location, and justify each choice

Identify clearances and ventilation openings required for a range of appliance categories

Sequence the commissioning steps for a new installation from purge through to consumer handover

Perform and record a pressure test and a leak test to the required test pressures and durations

Describe how to verify operating pressure, gas rate and combustion performance at the appliance

Assemble a handover pack listing what the consumer must be told and what must be left on site

Build a fault-finding decision tree covering no ignition, poor flame, low heat output and intermittent operation

Diagnose five written fault scenarios and state the test that confirms each diagnosis

Interpret combustion analyser readings and identify the likely cause of out-of-spec CO or CO2 values

Explain how to isolate and make safe a defective appliance before repair

Summarise consumer protection obligations including disclosure, warranties and complaint handling

Identify environmental duties covering spillage, refrigerant and gas release, and waste disposal

List personal and site safety controls required before and during gasfitting work

Explain the process for reporting notifiable incidents and unsafe installations

Re-run two timed commissioning scenarios to build speed and accuracy under exam conditions

Complete a mixed set of calculation questions across combustion, ventilation and pipe sizing

Review every previously missed question and write a corrected method for each

Practise explaining a safety decision aloud as you would to a consumer

Complete two full-length timed practice exams and score each by domain

Revisit the two lowest-scoring domains and close the specific gaps identified

Recite the key standards, test pressures and clearances from memory without notes

Finalise a one-page exam-day reference of figures and formulas you must recall
