Why Choose the Top-Down Burn Method?
The top-down burn is widely recognised as one of the most efficient and environmentally friendly ways to light a fire. By lighting the fire from the top, the smoke produced by the initial combustion passes through the hotter flames above, burning off more of the particulate matter. This results in:
- Reduced smoke output: Better for your chimney, your home, and the air quality.
- Increased efficiency: More heat from your wood, meaning you use less fuel.
- Cleaner burn: Less soot and creosote build-up in your chimney.

How to Master the Top-Down Burn: A Step-by-Step Guide
Here’s how to achieve the perfect top-down burn in your wood burner or open fire:
1. Start with Dry Wood: This is crucial for any efficient fire. Your logs should have a moisture content of 20% or below. Burning wet wood is inefficient, produces excessive smoke, and can lead to dangerous tar build-up in your chimney. You can easily check this with a moisture meter, readily available online at a reasonable price.
2. Lay Your Foundation: Place your larger, dry logs at the bottom of your stove or grate.
3. Build the "Hashtag": On top of the base logs, arrange your kindling in a criss-cross or hashtag (#) pattern. This allows for good airflow.
4. Position the Firelighter: Place your firelighter on the very top of the kindling stack.
5. Initial Airflow is Key:
- Door Ajar (Wood Burners): When first lighting, keep the stove door slightly ajar.
- Vents Open: Ensure both your primary and secondary air vents are fully open.
As a general guide, the primary vent is often located at the bottom of the stove (supplying air from underneath the fire) and the secondary vent (or airwash) is usually at the top (supplying air over the fire). However, every stove is different, so it is vital to consult your stove's instruction manual for specific guidance on its vents.
6. Light the Firelighter: Light the firelighter at the top.
7. Establish the Draught: Once the kindling is well alight and you can see an updraught has been achieved (the smoke is drawing cleanly up the chimney), you can shut the stove door.
8. Achieve Full Flame: Wait until the larger logs are fully burning.
9. Adjust for Efficiency:
- Primary Vent: Once the fire is in full flow and burning well, you can usually close the primary vent.
- Secondary Vent: The secondary vent now becomes your primary heat control.
Maintaining the Perfect Burn with a Stove Pipe Thermostat
To help you maintain the optimal burning temperature and efficiency, we highly recommend using a stove pipe thermostat. This simple device attaches to your flue pipe and gives you a clear indication of the temperature.
- Too Cold? If the temperature is too low, your fire isn't burning efficiently and may be producing more smoke. Open the secondary vent a little more to increase airflow and heat.
- Too Hot? If the temperature is excessively high, you risk damaging your stove or flue and are wasting fuel. Start to close the secondary vent to reduce the airflow and bring the temperature down to the optimal "Goldilocks zone."
Adding New Logs
When it's time to add more fuel:
- Open Vents: Fully open both the primary and secondary vents again before adding new logs.
- Add Dry Wood: Only add dry logs with 20% or less moisture content.
- Re-establish and Readjust: Once the new logs have caught and are burning well, readjust the vents as before (close primary, control with secondary).
Ending Your Fire Safely and Efficiently
As your fire dies down, continue to manage the vents to ensure the remaining fuel burns out completely and efficiently. Use a fire poker to reposition any unburnt fuel if necessary, always aiming to stay in that optimal temperature zone for as long as possible.
**Crucially, always ensure your fire is completely out before you go to bed or leave the house.**
The Dangers of Slumbering Your Fire: A Warning for Your Chimney & the Environment
It might seem convenient to let your fire smoulder overnight by closing down the vents and leaving a log to burn slowly. However, **never slumber (suffocate) your fuel.** This practice has several negative consequences:
- Environmental Impact: A slumbering fire produces significantly more smoke and harmful particulate emissions.
- Reduced Liner Life Expectancy: This type of incomplete combustion leads to excessive Stage 2/3 soot (tar) build-up in your chimney liner. Tar is highly flammable and can lead to chimney fires. It also corrodes your liner, reducing its lifespan.
Regular Sweeping: The Key to a Safe and Efficient Chimney
Even with the best burning practices, regular chimney sweeping is essential. A clean chimney:
- Ensures Safety: Removes flammable creosote and soot, significantly reducing the risk of chimney fires.
- Maintains Peak Efficiency: Allows your fire to burn optimally and your stove to perform as it should.
- Prevents Blockages: Clears out any debris, nests, or other obstructions that could impede the safe venting of smoke and fumes.
