SafeBurn Technology Explained
Safe & Efficient Heat
Bioethanol fireplaces are prized for real flames without chimneys or gas lines. At the heart of Le Feu’s performance is SafeBurn Technology—a burner design that uses a ceramic fibre insert to absorb fuel securely, stabilize the flame, and support cleaner combustion. This guide explains how SafeBurn works, why it improves everyday safety, and how to use it for the best experience at home.
What is SafeBurn Technology?
SafeBurn is Le Feu’s burner system designed for **clean combustion and secure fuel handling**. A precision-built reservoir houses a ceramic fibre insert that absorbs approved bioethanol fuel. This structure helps moderate evaporation, improving flame stability and reducing splashes compared with open-pool burners.
How SafeBurn works
When you add bioethanol to the burner, the ceramic fibre insert absorbs the liquid. During ignition, heat transforms a portion of that fuel into vapour, which mixes with air and combusts as a steady, visible flame. The insert’s structure helps regulate fuel availability at the flame surface for smoother, more efficient burning.
- Fuel absorption: The insert acts like a secure reservoir for approved bioethanol.
- Vapour release: Heat converts a controlled amount of fuel into flammable vapour.
- Stable flame: Regulated vapour flow supports consistent flame shape and intensity.
- Cleaner burn: Designed to reduce smoke and soot when used with proper fuel and ventilation.
SafeBurn balances flame stability, clean combustion, and everyday usability—making bioethanol fireplaces easier and safer to enjoy.
Key benefits for daily use
Secure fuel handling
The ceramic insert holds fuel in place for controlled evaporation and a calmer surface during operation.
Smoother ignition
Vapour-based combustion promotes more consistent lighting and steady flame characteristics.
Clean, ventless comfort
With approved bioethanol, emissions are mainly water vapour and small amounts of CO₂—no smoke or ash.
Low maintenance
No ash or soot cleanup. Wipe the burner and dome surfaces as part of simple routine care.
Safety, certification, and best practices
Le Feu bioethanol fireplaces are certified to ANSI/CAN/UL/ULC 1370 for indoor use when operated as directed. SafeBurn is one part of a comprehensive approach that includes proper installation, approved fuel, and responsible handling. Follow these essentials every time:
- Use only approved bioethanol fuel. Never use gasoline, gel, or other fuels.
- Extinguish the flame and allow at least 30 minutes to cool before refilling.
- Keep the fireplace on a stable, heat-resistant surface away from drafts and flammables.
- Ensure normal room ventilation. Do not modify the burner or insert.
- Keep fuel containers capped, upright, and stored away from heat sources.
Heat output, burn time, and efficiency
Performance varies by model and conditions, but Le Feu’s bioethanol fireplaces typically produce approximately 2.0–3.0 kWh of heat—similar to a small electric heater—and can comfortably enhance the ambiance of rooms around 200 ft³.
- Heat output: ~2.0–3.0 kWh (model and damper setting dependent)
- Burn time: ~2–3 hours per 1 L (with damper fully open; conditions may vary)
- Combustion: Clean burn with approved bioethanol fuel and normal room ventilation
Filling, lighting, and maintenance
Operation basics
- Confirm the burner is cool and extinguished. Open the damper if applicable.
- Using a funnel, fill with approved bioethanol to the indicated level; wipe any spills immediately.
- Ignite with a long lighter; keep hands, sleeves, and objects away from the flame path.
- To extinguish, close the damper completely. Allow at least 30 minutes for cooldown before refilling.
Simple cleaning
- When cool, clean the dome exterior with a damp, lint-free cloth.
- Wipe the burner using a soft cotton cloth lightly moistened with bioethanol.
- Periodically inspect the burner and insert; follow manufacturer guidance for care and replacement.
Quick FAQ
What makes SafeBurn different from a standard burner?
SafeBurn uses a ceramic fibre insert that absorbs bioethanol to control evaporation and support a stable flame for cleaner, easier operation.
Does SafeBurn eliminate the need for ventilation?
No. While combustion is clean with approved fuel, you should always ensure normal room ventilation for indoor use.
How much heat can I expect?
Most Le Feu models produce around 2.0–3.0 kWh—similar to a small heater—ideal for enhancing comfort and ambiance.
Can I refill immediately after turning it off?
No. Always wait at least 30 minutes for the burner to cool completely before refilling to ensure safe handling.
Which fuel should I use?
Use only high-quality, approved bioethanol fuel. Other fuels are unsafe and may damage the burner or affect performance.
