In the heart of winter, there’s nothing quite like the crackle of a log burner warming your home. But behind every efficient, safe, and eco-friendly wood heater is a reliable log burner flue kit. Whether you’re upgrading your existing wood heater or installing a new one, selecting the right flue kit is essential for performance, compliance, and safety.
At Stainless Flue, we specialise in premium-quality flue kits and components across Australia. This comprehensive guide explores everything you need to know about log burner flue kits—from their importance and types to installation, regulations, and how Stainless Flue provides durable, compliant solutions.
What Is a Log Burner Flue Kit?
A log burner flue kit is a system of pipes and components designed to safely vent smoke and gases produced by a wood heater or log burner out of a building. It acts as the chimney for your heating appliance, ensuring proper draft and safe indoor air quality.
A Complete Kit Typically Includes:
- Inner stainless steel flue pipes
- Outer galvanised or stainless steel casings (for triple-skin systems)
- Ceiling plate and spacer
- Roof flashing (pitched or flat)
- Cowl or rain cap
- Firestop spacers
- Wall or ceiling supports
Why the Flue Kit Matters
The flue system is not just an accessory—it is critical for safety and functionality:
✅ Safe Smoke Extraction
A poorly installed or incompatible flue kit can cause backdraft, carbon monoxide leaks, or smoke buildup—posing serious health and fire hazards.
✅ Efficient Drafting
A properly sized and installed flue allows for optimal combustion and efficient heat output from your log burner.
✅ Australian Standards Compliance
All flue kits must adhere to AS/NZS 2918:2018, the Australian Standard governing solid fuel appliance installations.
Types of Flue Systems
1. Single-Skin Flue
- Typically used inside the room
- Made from stainless steel or mild steel
- Transfers significant heat to surrounding air
- Not compliant alone—usually used with a triple-skin shield
2. Double-Skin Flue (Insulated)
- Inner stainless flue with outer casing and insulation
- Reduces external surface temperature
- Better drafting and safer performance
3. Triple-Skin Flue Kit
- Often required for ceiling/wall penetrations and roof exits
- Three layers with air insulation in between
- Best for high-temperature and long-term durability
- Required to meet Australian clearance regulations
Roof Types and Flue Kit Compatibility
Stainless Flue supplies log burner flue kit tailored to all common Australian roof types:
- Pitched roof flashing for tile or Colorbond® roofs
- Flat roof flashing for modern architectural builds
- Custom fabricated flashings for unique installations
We also offer solutions for horizontal wall exit flues, though vertical exit is usually preferred for optimal draft.

DIY vs. Professional Installation
While flue kits are available for DIY installation, Australian law often requires certified installation by a licensed technician—especially for insurance compliance and building codes.
DIY Kits
Our flue kits come with detailed instructions, making them suitable for builders or experienced handymen.
Professional Installers
We work closely with certified installers across Australia and can recommend a trusted professional in your area.
Flue Height and Clearance Regulations in Australia
Australian regulations are strict about flue height and proximity to combustible materials:
- Minimum 4.6 metres above the floor
- Must extend at least 600mm above the roof ridgeline
- Maintain minimum 25mm clearance from combustibles with insulated flue
- Use approved ceiling and roof penetrations to avoid heat transfer
Always check with your local council or a certified installer for site-specific compliance.
Maintenance and Cleaning Tips
Over time, soot and creosote can accumulate inside the flue, reducing performance and increasing fire risk.
Cleaning Tips:
- Inspect and clean the flue at least once per season
- Use a chimney brush sized to your flue diameter
- Stainless Flue offers easy-clean designs and access caps
- Hire a professional sweep for hard-to-reach installations
Common Installation Challenges
Problem: Backdraft or smoke leakage
Solution: Ensure correct flue height and eliminate air leaks. We offer anti-downdraft cowls to prevent backflow.
Problem: Roof leaks around flashing
Solution: Use high-quality silicone sealants and weatherproof flashing. Our kits include waterproof EPDM flashings for Australian roofs.
Problem: Combustion smell indoors
Solution: Check for gaps in inner flue joins and use fire-resistant sealants. Our flue joints come with secure lock rings.
Custom Kits for Builders and Architects
We also offer customised flue kits for architectural builds, passive homes, off-grid cabins, and commercial spaces. Work with our fabrication team to design the right flue system for your needs.
