Look Inside the Book

Every page has one big labelled drawing and a box with the numbers and steps you need to know:

The Problem Isn't You. It's How It Was Explained to You.

You're on a job where the run starts in copper inside and finishes in a buried section out the back. You have to decide what pipe goes where. You know the trade, but which material is allowed in which place?

In the standard it's split across clauses and tables: materials in one section, locations in another, the exceptions further on. You read it at night and by morning the four materials have blurred into one.

Copper, steel, PE and multilayer: multilayer never above ground outside a building (cl. 5.3.16)

In the book it's one page: copper, steel, PE and multilayer drawn side by side, each in the place it belongs. Multilayer is marked clearly: never above ground outside a building.

The rest of the syllabus is done the same way: pipe sizing by pressure drop, the soundness test in fixed steps, Type A or Type B, combustion air, commissioning. Each one has its own page.

You look at the drawing, you see where each pipe goes, and you make the call on site without opening the standard again.

COMPARE FOR YOURSELF

The Same Topic, Two Ways to Study It

THIS
  • The standard: lines and lines of clauses
  • Installation layouts explained only in words
  • You walk into the exam with doubts
Before any work begins, the gasfitter is expected to identify where the consumer installation starts and where it ends, which is different for natural gas and for LPG, and then to consider each component between those two points in turn, including pressure regulation, metering, the piping itself, isolation, the connection to the appliance, the appliance and the removal of the products of combustion, keeping in mind that each of these components carries its own requirements, conditions and exceptions, which are explained in separate places and have to be read together.
FOR THIS
  • The whole installation in one drawing
  • The eight stops in a box
  • You see it and you get it
Regulator → meter → pipe → valve → connector → appliance → flame → flue: one line, eight stops.

One Page, One Topic, All Clear

Think of it this way:

You've finished a new install and the gauge is on the test point. You need to know what the soundness test actually proves, and you need it now, not after twenty minutes in the standard.

You open the soundness testing page and it's all drawn: gauge, isolation, test point and the fixed steps in order. New installation: zero drop.

New installation: zero drop. Allowable leakage only for existing natural gas standard installations up to 30 L.

Same with pipe sizing, gas rate from the meter, ventilation openings, flue terminal clearances and LPG cylinder location: each one on its own page.

Gasfitting Licence Illustrated is 9 parts and 62 topics, all drawn, and it finishes with a revision part: the whole installation on one page and the numbers to have at hand.

What you see drawn, you don't have to memorize.

Frequently Asked Questions

Is it for me if I've been a plumber for years and I'm now adding gasfitting?

Yes. It doesn't explain what a tap is: it goes straight to gas, from the meter or cylinder to the flue, in one fixed order. It's written for Australia and AS/NZS 5601.1, with kPa, MJ/h and metres, no inches or psi.

Where does the content come from?

From AS/NZS 5601.1 (current edition), which is used across Australia, and the Victorian gasfitting licence and registration requirements. If you're licensed in another state, the standard is the same, but check your state regulator's local rules and exam requirements. The tables of the standard are not reproduced: the book uses its own drawn examples. Always check the current edition and the manufacturer's instructions.

Is it official material?

No. It's independent study material, not produced, approved or endorsed by Standards Australia or any regulator.

Does it replace the course or the training?

No. It helps you revise what you learn in your training and on the job, but it doesn't replace accredited training, supervised work or the licence, and it doesn't give you a certificate or count towards any unit.

Are the practice questions the ones in the exam?

No. They're exam-style questions written for this book, each answer linked to the page it comes from.

When and how does it arrive?

As a PDF by email, to the address you enter at checkout. The 2 bonus books come with it.

Do I have to pay every month?

No. It's a one-off payment, with no subscription.

Can I have it on paper?

Yes. The PDF is made to print, so you can keep the pages you need in the ute or on the job.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.

Before You Close This Page

No more rereading the standard with nothing sticking.
