Heavy-duty, lightweight brass power burner for roofing, waterproofing, preheating, defrosting and other demanding heating applications. External mixing pipe guarantees a stable windproof flame in all weather conditions. 26kW, 2000g/h. Working pressure 2–4 bar. M20 × 1 thread fits all Pro 86/88 neck tubes. A 4 bar regulator is recommended for full output.
The 2942 is the power burner option in the standard Pro 86/88 burner range — a 32mm brass head delivering 26kW for roofing, waterproofing and large-scale heating tasks on the Pro handle system. The defining feature is the external mixing pipe, which draws in ambient air to create a stable, windproof flame in all weather conditions — both at low flame and full output. This gives the 2942 reliable performance in the exposed conditions typical of rooftop and open-site work, where a standard open-flame burner would be disrupted by wind.
With 26kW achieved at 4 bar. Gas consumption of 2000g/h is measured at the rated pressure. For full waterproofing and roofing output, a 4 bar high-pressure propane regulator and a 13kg or larger propane cylinder are recommended.
