Understanding the AS/NZS 2918:2026 Update
In early 2026, Standards Australia released the updated AS/NZS 2918 guidelines for domestic solid fuel burning appliances. Whether you are installing a compact heater in a Melbourne unit or a large cooking stove in a rural Western Australia homestead, compliance is non-negotiable. The 2026 update places stricter focus on “clearance to combustibles,” ensuring that modern high-heat stoves do not pose a risk to timber frames or plasterboard walls.
The Importance of Floor Protectors (Hearths)
A common point of confusion for Australian homeowners is the size and material of the hearth. Under the current 2026 standards, a floor protector must not only be non-combustible but must also meet specific thermal resistance ratings. For heavy cast-iron stoves like the J.A. Roby range, the hearth must extend a minimum of 300mm to 500mm in front of the fuel loading door to protect your flooring from stray embers and radiant heat.
Vertical Clearance and Flue Height Requirements
To ensure a “natural draft” (the force that pulls smoke up and out), Australian standards require a minimum flue height. In 2026, most installations require at least 4.6 metres from the hearth to the top of the flue cowl. Furthermore, if your home is located in a high-wind area or near tall trees, you may need an additional meter to prevent “downdrafts” that can push smoke back into your living area.
Why You Need a Certified Installer
While the “DIY” spirit is strong in Australia, 2026 insurance policies often require a Certificate of Compliance from a licensed installer. At WoodCookers, we strongly recommend using an AHHA (Australian Home Heating Association) certified technician. They ensure that your triple-skin flue is installed with the correct “drop box” through the ceiling, maintaining the fire-rated integrity of your roof space and keeping your manufacturer’s warranty valid.
