If you’re thinking about installing a wood heater in your home, chances are you’ve heard of LOPI. Known for their beautifully crafted, high-performance wood and gas heaters, LOPI products have gained a solid reputation in Australia for both their style and heating efficiency. But no matter how good your heater is, it’s the flue pipe that keeps your installation safe, efficient, and compliant with Australian standards.
So let’s break it down. Whether you’re upgrading an old system or installing a new LOPI wood heater, this guide covers everything you need to know about LOPI flue pipes—from components to installation and maintenance.
What is LOPI?
LOPI is a renowned American brand that’s been producing wood, gas, and pellet heating systems for over 40 years. Their heaters are known for superior design, high thermal efficiency, and long-lasting performance. In Australia, LOPI wood heaters are popular in both residential and rural homes due to their quality and AS/NZS compliance.
Why Choose a LOPI Flue Pipe?
Trusted American Brand with Local Aussie Support
LOPI products are distributed through a strong network of authorised dealers in Australia, making service, support, and replacement parts easily accessible.
Built for Performance and Safety
A LOPI flue pipe isn’t just a metal tube—it’s part of a precisely engineered ventilation system that optimizes draft, prevents backflow, and ensures proper removal of smoke and gases.
LOPI Flue Pipe Materials
Stainless Steel Construction
LOPI flue pipes are crafted from high-grade stainless steel that can withstand extreme temperatures and corrosion, ideal for Australian weather—from the coastal humidity of Queensland to the winter chills of Victoria.
Double and Triple Wall Options
- Double-wall flue pipes provide insulation between layers to maintain high exhaust temps and reduce creosote buildup.
- Triple-wall flue systems offer an extra layer of protection and heat shielding, especially useful in multi-storey homes.
LOPI Flue Kit Components
A standard LOPI flue kit includes:
- Stainless steel inner pipe – Directs combustion gases upward
- Outer flue casing – Provides thermal insulation
- Ceiling ring and fire stop spacer
- Roof flashing – Seals roof penetrations
- Chimney cap / cowl – Prevents rain and downdrafts
- Wall brackets and storm collars
These components are precision-fit to ensure maximum safety, thermal efficiency, and compliance.
Understanding LOPI’s Flue Technology
Air-Cooled Design
LOPI flue systems are designed with air-cooled insulation that allows cool ambient air to circulate between flue walls. This reduces heat transfer and increases safety.
Superior Draft Control
A well-engineered draft system ensures efficient fuel combustion and eliminates smoke backflow. LOPI’s vertical flue systems are excellent for maintaining consistent draft levels.
AS/NZS 2918 Compliant
All LOPI flue kits meet Australian safety standards, especially AS/NZS 2918 for the installation of solid fuel heating appliances.
Compatibility with LOPI Wood Heaters
LOPI flue pipes are specially designed to integrate seamlessly with models such as:
- LOPI Answer 2020
- LOPI Endeavor
- LOPI Liberty
Each flue kit is tailored for optimal compatibility, ensuring easy connection and correct clearances.
Installation of LOPI Flue Pipes
Through-Roof vs Through-Wall Installation
- Through-roof systems are the most efficient and commonly used with LOPI wood heaters.
- Through-wall systems require extra components like wall thimbles and elbows but are great where roof access is limited.
Clearance Requirements in Australia
LOPI flue pipes offer reduced clearance requirements due to their insulated design. For example, double-wall systems may require as little as 25mm–50mm clearance from combustibles.
Installer Tips for First-Timers
- Always use a laser level or plumb bob for vertical alignment.
- Follow LOPI’s flue configuration charts for correct length and offset.
- Seal joints with high-temp silicone or flue cement.
Safety Considerations
Fire Prevention with Insulated Pipes
Insulated flue pipes help prevent overheating of walls or ceilings, a leading cause of house fires in older stove installations.
Maintaining Safe Distances
Always observe the minimum clearance distances as outlined in the installation manual. Use fire-stop spacers and ceiling plates to maintain separation.
Proper Sealing and Bracing
Ensure all roof and ceiling penetrations are weatherproofed. Use roof flashing and storm collars to keep water out and stainless wall brackets to stabilize tall runs.
Maintenance and Cleaning
How to Clean Your LOPI Flue
Use a chimney brush suited to your pipe diameter. Insert from the top or bottom and scrub out soot and creosote.
Identifying Blockages or Creosote Buildup
Watch for:
- Black flaky soot or tar-like deposits
- Slow draw or smoke leakage into room
- Smoky smell near the heater
When to Replace Components
Replace your flue pipe if you notice:
- Rust or corrosion
- Cracked joints or failed seals
- Loose components that compromise safety
