<p>A hot-air blower has a nozzle 20 for injecting fuel into a combustion chamber 2a a fuel pump 18 for supplying fuel to the nozzle 20, and a combustion fan 22 for discharging hot-air from the combustion chamber 2a. A quantity of air supplied to the combustion chamber 2a by the combustion fan 22 is controlled by a control unit 26. The control unit 26 is provided for increasing the quantity of supplied air during ignition of the injected fuel so as to compensate a reduction of the quantity of the supplied air caused by an increase of the static pressure in the combustion chamber 2a. <IMAGE></p>
