Abstract

An arrangement having an auxiliary heater, a catalytic converter (12) for catalytic post-combustion of exhaust gas from the heater, a muffler (14) for damping of the noise caused by the exhaust gas, and an exhaust line for removing exhaust gas from the auxiliary heater. In order especially to devise an auxiliary heater in which the muffler and the catalytic converter can be installed relatively easily, the muffler (14) and the catalytic converter (12) are combined in sing module (10) that can be located on the exhaust line.
