BonFeu Heavy Duty Steel Extension Stove Pipe Flue for Outdoor Garden Fireplaces

Direct wood smoke away from your seating area and optimize your outdoor heating configuration with a premium flue extension. The BonFeu Extension Stove Pipe is an industrial-grade structural accessory engineered specifically to increase the chimney height of your garden fireplace. By elevating the smoke release point, this heavy-duty flue pipe improves draft efficiency and ensures a cleaner burn, keeping your terrace lounge layout beautifully clear, fresh, and exceptionally comfortable for your guests long after sunset.

Heavy-Gauge All-Weather Steel Architecture

Ordinary thin metal chimney flues rapidly degrade, peel, or rust under the intense heat of roaring log fires and unpredictable UK weather. This professional stove pipe extension is forged from thick, 2-3 mm high-tensile structural steel, ensuring permanent rigidity and reliable performance over extreme high-temperature environments. Available in both a classic heat-resistant matte Black finish and an authentic natural Rust-treated alloy, it seamlessly integrates with your existing cooker setup while providing a robust defense against atmospheric wear.

Precision Smart-Fit Telescopic Installation

Achieve an ultra-secure, smoke-tight physical connection with a highly practical telescopic design. This 10 cm diameter pipe is custom-engineered to retract directly inside your fireplace's main flue structure, locking solidly in place with zero loose seams or draft leaks. Because the sections overlap securely upon installation, the final assembled length sits approximately 5 cm shorter than the raw dimension, providing a perfectly stable, rattle-free chimney extension that withstands heavy garden crosswinds.

Tailored Multi-Size Framework Configurations

Customize your terrace layout footprint effortlessly by selecting the ideal structural extension height to match your patio or pergola setting. The compact 44 cm pipe is perfect for adding a subtle height boost to smaller seating areas, weighing a balanced 1.7 kg. For large-scale entertaining areas or grand garden landscapes requiring maximum smoke elevation, select the monumental 66 cm flue pipe profile, which delivers an impressive 2.0 kg weighted thermal run.
