Ensuring a gas installation is safe is a fundamental responsibility for all gasfitters when performing inspection and servicing of Type A appliances. As a result, understanding the required scope of this work is critical for gasfitters to be able to complete it successfully and meet their responsibilities under the Gas Safety Act and subordinate regulations. When servicing any open-flue gas appliance always start by inspecting the installation.
Your inspection ‘checklist’ must include the following items:
Once your inspection ‘checklist’ is complete, you can commence your servicing work, which may include items from the following list:

If you detect any rise in the level of carbon monoxide above your background reading, you should find and eliminate the cause of the spillage.
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’s 24/7 gasfitter CO isolation hotline on 1800 652 563 and select option 5. The reporting hotline is ONLY to be called when the customer is refusing to have their appliance isolated and you cannot make it safe. For non-compliance queries, call 1800 652 563 – Option 3.
When calling ESV, please ensure you supply the following information:
An ESV inspector will contact you soon after receiving these details to obtain further information. They will then contact your client in an attempt to resolve the matter.
As part of the resolution, ESV may offer to carry out an additional inspection, re-iterating 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.
When you service an open-flue gas heater and detect negative air 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, 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 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:
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 where we have been appropriately notified of the situation regarding your client’s gas heater.
