In the method, a silicon rod is disposed inside an ignition device, and a first voltage is applied to the silicon rod by means of a first power supply unit, wherein the voltage is sufficient to ignite the silicon rod. Optionally, the silicon rod may be heated by means of a current flow and/or by means of an external heating unit to a temperature within a predetermined temperature range, thereafter. The silicon rod is removed from the ignition device and may be exposed to a depositing process inside a CVD-reactor, thereafter. The ignition of the silicon rod outside the CVD-reactor facilitates a new ignition for the depositing process. The device comprises a casing having a chamber for receiving at least one silicon rod. In the chamber, at least one pair of contact electrodes is arranged, in order to hold at least one silicon rod therebetween. Furthermore, a first power supply unit having at least one transformer is provided, wherein each output of the transformer is connected to one contacting electrode of a pair, respectively.
