Abstract: In an ignition appliance for a heat generator, the supply lines for air (70) and fuel gas (60) are led directly into a flame tube (40). The igniter (51) is arranged in an ignition space (50) remote from the flame tube (40) and connected to the flame tube (40). The ignition space (50) is connected to the air supply passage (70) and the gas supply passage (60) via connecting ducts (55, 56).
