LOPI Flue Pipe – Premium Flue Systems for Lopi Wood Heaters in Australia
Lopi wood heaters are renowned across Australia for their high efficiency, striking designs, and powerful heating capabilities. However, to ensure safe operation and optimal performance, these wood heaters must be paired with the correct LOPI flue pipe system. A high-quality flue not only enhances draft efficiency but also protects your home from potential fire risks and ensures full compliance with Australian building standards.
In this in-depth guide, we explore everything you need to know about Lopi flue pipes—including types, components, installation best practices, and where to buy certified flue kits tailored for Lopi appliances.
What is a LOPI Flue Pipe?
A LOPI flue pipe is the chimney system specifically designed to vent smoke and combustion gases from Lopi wood heaters. These flue pipes are engineered to handle extremely high temperatures and must be manufactured to comply with AS/NZS 2918:2018, the standard governing solid-fuel heating appliances and flue systems in Australia.
Lopi heaters typically use a 6-inch (150mm) inner diameter flue system, but always consult the specific model’s manual for exact specifications.
Why the Right Flue Pipe Matters for Lopi Heaters
- Safety Compliance: An incorrect flue system can be dangerous and may void your insurance.
- Maximum Efficiency: Lopi heaters are built for performance, and a proper flue ensures they operate at peak capacity.
- Long-Term Durability: A certified flue resists corrosion and heat damage for decades.
- Prevention of Smoke Spillage: A well-designed flue ensures consistent updraft and prevents back-puffing.
- Condensation Management: Correct flue insulation prevents moisture buildup inside the chimney.

Installation Tips for LOPI Flue Pipes
- Always follow AS/NZS 2918:2018 guidelines.
- Ensure proper clearances from combustible materials—typically 25mm to 50mm for triple skin, 150mm+ for single or double skin.
- Use certified flashings and weather seals to prevent leaks.
- Seal all joints with high-temp silicone to prevent smoke leakage.
