Log Burner Flue Kit in Australia – A Complete Guide by Stainlessflue AU
As Australian winters grow colder and energy costs rise, more homeowners are turning to log burners (wood heaters) for efficient, sustainable, and cozy home heating. But a log burner is only as good as its flue system—a vital component that ensures the safe removal of smoke, gases, and soot, while maximizing heat retention and appliance performance.
That’s where a log burner flue kit becomes essential. A complete, compliant flue kit allows safe installation and operation of your wood heater, whether in a suburban living room, a rural cottage, or a modern off-grid retreat.
In Australia, Stainlessflue AU has become a go-to provider for high-quality, AS/NZS-compliant log burner flue kits built to endure the harshest conditions. This article explores everything you need to know about log burner flue kits, their importance, components, installation, safety tips, and why Stainlessflue AU is trusted by professionals and homeowners alike.
What Is a Log Burner Flue Kit?
A Log burner flue kit is a set of pre-fabricated, modular components used to safely vent a wood-burning stove or fireplace. It creates a sealed, insulated pathway for smoke and combustion gases to exit your home, preventing harmful buildup while increasing heating efficiency.
Key Functions:
- Exhausts smoke, carbon monoxide, and fumes
- Creates necessary draft for proper combustion
- Minimizes creosote buildup
- Protects the building from heat damage
- Meets safety and building code compliance
Flue kits are essential for DIY installations, renovations, or replacing outdated or non-compliant systems. When purchased as a complete kit from trusted suppliers like Stainlessflue AU, they offer peace of mind and hassle-free installation.
Why You Need a Proper Flue Kit for Your Wood Heater
Many Australians still believe that installing a log burner is simply about placing the unit and attaching a pipe. The reality is more complex—and safety-critical. Improper flue setups can cause:
- Back-drafting (smoke entering the room)
- Fire hazards from excessive heat or creosote
- Structural damage
- Insurance and legal issues from non-compliance
Benefits of a Proper Flue Kit:
Safe and efficient exhaust
Improved heater performance
Reduced fuel usage
Lower maintenance and cleaning frequency
Full compliance with AS/NZS 2918 standards
Quick installation with clear instructions

Installation Tips & Safety Guidelines
Installing a flue system is not just about assembly—it must comply with spacing, insulation, and air flow standards.
Key Installation Guidelines:
- Maintain minimum clearance from combustibles (25mm to 50mm, depending on setup)
- Use triple skin where flue passes through ceiling/roof
- Install the flue at a height that ensures proper draw (typically 600mm above the roofline)
- Seal flashing and collars to prevent leaks
- Use elbows and offsets only when necessary to preserve airflow
- Never install single-skin flue through ceilings or walls
Always consult local council or building codes before installation, or engage a licensed professional if unsure.
How to Select the Right Flue Kit
Choosing the correct kit depends on several factors:
| Factor | Consideration |
|---|---|
| Ceiling Height | Measure from heater top to ceiling and from ceiling to roof |
| Roof Type | Flat, pitched, cathedral, or skillion roofs |
| Location | Internal vs external flue system |
| Wood Heater Model | Outlet size, rear/top exit, certification requirements |
| Bushfire Zone | Spark arresters and extra shielding may be required |

(FAQ)
Do I need a professional to install my flue kit?
While many Stainlessflue AU kits are DIY-friendly, hiring a certified technician is recommended if you’re unsure or need certification for insurance purposes.
What size flue do I need?
Most wood heaters use a 6″ (150mm) internal flue, but this can vary. Always check your heater’s manual or contact Stainlessflue AU for help.
Can I use an old single-skin flue?
No. Modern standards require insulated or twin/triple skin flues through ceilings, walls, or roofs.
Do flue kits work with fireplaces?
Yes, but the setup may vary. Contact Stainlessflue AU for fireplace-compatible kits.
Conclusion:
A log burner without a reliable flue is not only inefficient—it’s unsafe. Whether you’re installing a wood heater in a country home, a new build, or a stylish renovation, investing in a certified, durable, and easy-to-install flue kit is a must.
