What Is a Stove Pipe for a Wood Stove?

A Stove pipe for wood stove, also referred to as a flue pipe, is the component that connects your wood-burning stove to the chimney or flue system. Its function is to:

• Channel combustion gases, smoke, and particulates from the stove
• Facilitate proper airflow for efficient burning
• Protect indoor air quality
• Prevent fire hazards by ensuring safe exhaust

While it may appear to be a simple metal duct, its design, material, and installation are critical to your home’s safety and heating performance.

Why Stove Pipe Quality Matters

The stove pipe experiences extremely high temperatures, fluctuating pressures, and exposure to corrosive byproducts of combustion. Using poor-quality or incorrectly sized pipe can result in:

• Dangerous creosote buildup
• Reduced draft and efficiency
• Smoke leakage inside the home
• Violations of building regulations
• Risk of chimney fires

Stainlessflue AU manufactures stove pipes that are AS/NZS 2918 compliant, ensuring safety and durability you can trust.

Key Components of a Flue System

A full stove flue system includes:

• Stove Pipe: Connects directly to the stove’s flue collar
• Flue Liner or Chimney Pipe: Carries exhaust gases through the wall or roof
• Ceiling Plate or Wall Thimble: Provides a safe transition through surfaces
• Storm Collar and Flashing: Seals around roof penetrations
• Chimney Cap or Cowl: Prevents rain, birds, and debris from entering the system
• Firestop Spacers: Maintain proper clearances from combustibles
• Support Brackets: Secure the pipe in place vertically

Stainlessflue AU offers complete kits with all of these components included for easy installation.

Single Wall vs Double Wall Stove Pipes

Single Wall Stove Pipes

• Constructed from one layer of steel
• Require 450mm clearance from combustibles
• Emit more heat into the room
• Lower initial cost
• Not ideal for through-wall or ceiling transitions

Double Wall Stove Pipes

• Two layers of steel with an insulating air gap
• Require only 150mm clearance
• Retain higher internal temperatures, improving draft
• Safer for long runs or installations in tight spaces
• Ideal for modern home compliance

Stainlessflue AU supplies both single and double wall pipes, including black-finish and stainless options.

Understanding Australian Standards (AS/NZS 2918)

The AS/NZS 2918:2018 is the primary standard governing solid fuel heating appliances in Australia. It outlines requirements for:

• Minimum clearances from combustibles
• Proper construction of flue systems
• Thermal protection around flue exits
• Flue termination heights above rooflines
• Installation safety signage and certification

All Stainlessflue AU stove pipes and kits are tested and certified to meet or exceed these national safety requirements.

Choosing the Right Stove Pipe Diameter

The most common diameters for wood stove pipes in Australia are:

• 5 inch (125mm)
• 6 inch (150mm)
• 8 inch (200mm)

Your stove’s manufacturer instructions will specify the correct flue diameter. Using a mismatched size can lead to poor draft and increased creosote accumulation.

Stainlessflue AU stocks all major diameters and can advise on compatibility.

Installation Requirements & Best Practices

Installing a stove pipe involves:

• Connecting the pipe to the stove outlet using sealed joints
• Running the pipe vertically wherever possible (90° bends reduce efficiency)
• Maintaining required clearances from combustibles
• Securing with brackets and locking bands
• Sealing ceiling or wall penetrations with fire-rated spacers
• Extending the flue to required heights (usually 600mm above the highest point within 3 meters)

Professional installation is recommended, but Stainlessflue AU provides clear diagrams and support for DIY-friendly kits.

Through-Wall and Through-Roof Configurations

Depending on your home design, the stove pipe may pass:

• Through the ceiling and roof using vertical runs (preferred method)
• Horizontally through a wall with a 90° elbow and wall thimble

Vertical configurations improve draft performance and reduce buildup, while horizontal options may be necessary for small homes or limited ceiling space. Stainlessflue AU provides kits for both styles.

Maintenance and Safety Checks

To ensure optimal performance and safety:

• Inspect the flue every 1–2 months during heating season
• Clean soot and creosote buildup with a brush or rotary tool
• Check for leaks at joints and fittings
• Verify that chimney caps are clear of obstructions
• Schedule a professional inspection at least annually

We also stock flue cleaning tools and accessories to support long-term maintenance.

Common Issues and How to Avoid Them

Issue: Smoke leaking into the room
Fix: Seal all joints properly; ensure adequate draft

Issue: Creosote buildup
Fix: Burn seasoned wood; maintain flue temperature; clean regularly
