On-demand 2020 Gas Heater Safety Webinar
The 2020 Gas Heater Safety Webinars is now available on-demand, whenever and wherever you need it, so you can watch when it works for you.
In the video, Victorian Building Authority, Energy Safe Victoria and Master Plumbers technical experts cover the latest information on carbon monoxide testing and the safe operation of gas appliances.
Type A Appliance Gasfitter Toolkit
ESV has developed a Type A Appliance Gasfitters Toolkit to provide you with guidance on keeping safe, and information to assist you in keeping your clients’ gas heaters operating in a safe manner.
Carbon Monoxide Spillage Testing
What to do when you detect carbon monoxide spillage
When testing gas appliances, if you detect any rise in the level of carbon monoxide above your background reading, you’re obligated to eliminate the cause of the spillage and ensure the property made safe.
If this is not possible, or you are unable to eliminate the cause of the spillage, the appliance must be isolated with the consent of your client.
If your client refuses to allow you to isolate their gas appliance, you must contact Energy Safe Victoria on 1800 652 563 (select option 5).
When calling ESV, please ensure you supply the following information:
- your name, licence number and mobile telephone number
- your customer’s name, address and telephone number
- the type of heater spilling carbon monoxide
- the level of carbon monoxide spillage detected (in parts per million).
An ESV inspector will contact you soon after receiving these details to obtain further information. They will then contact your client to resolve the matter.
As part of the resolution, ESV may offer to carry out an additional inspection. The ESV inspector will remind the client of the dangers and consequences of carbon monoxide spillage. They will also inform your client that their gas supplier must withdraw supply to the premises if the heater is found to be unsafe.
What to do when there is no spillage, but your client won’t let you rectify a negative air pressure situation
When you service an open-flue gas heater and detect negative pressure, you have a responsibility to make the situation safe and inform your client of your findings.
To help you explain the potential dangers of carbon monoxide and the steps needed to overcome negative pressure, the VBA and Energy Safe Victoria have prepared an advice letter (PDF, 199.74 KB), which you should fill in and provide to your client after completing an inspection and service.
In all cases, clearing existing vents and installing additional permanent ventilation are the recommended solutions for overcoming negative pressure. If this is not possible, check with your client to see whether they are happy for you to isolate their heater.
Sometimes, though, a client may not want you isolating their gas heater or installing additional ventilation in their home. In such cases, you should take the following action:
- Hand your client the advice letter and reiterate the potential dangers of carbon monoxide and the effect of negative pressure.
- Remind your client of the need to install additional ventilation in their home to overcome the effect of negative pressure.
- Inform your client that you will notify the VBA of the situation, and that the VBA will contact them directly.
- Notify the VBA as soon as possible by emailing firstname.lastname@example.org or by calling 1300 815 127 during business hours. Make sure you supply the client’s contact details, site address and heater details.
Once you have notified the VBA of your actions regarding a client’s gas appliance, your job is done. The VBA will take over and work with your client to resolve their negative air pressure situation.
Please note: The VBA will not take enforcement action against a registered or licensed gasfitter if we have been appropriately notified of the situation regarding your client’s gas heater.

Negative pressure and carbon monoxide spillage training video
To support all Victorian gasfitters and Type A Appliance Servicing plumbers, Energy Safe Victoria have produced a short instructional video demonstrating the steps required to correctly test for negative air pressure and carbon monoxide spillage.
The video guides you through these important tests, outlining faults common to gas heaters and demonstrating how to identify and combat negative air pressure.
It also provides you with information to be aware of when testing for carbon monoxide spillage. This includes safety tips for carrying out this important work.
You should refer to this video before servicing or testing open-flue gas appliances, as it explains what you must do if negative pressure or carbon monoxide is found in a building.
It may also be useful for homeowners and residents to watch this video to find out why their gas heating appliances should be serviced and tested every two years.
