An installation can adjust gas supply in a reaction chamber according to the conditions in the reaction chamber. The installation comprises sensors, a gas-supplying panel and a driving device. The sensors are located in the reaction chamber to sense the conditions in the reaction chamber. The gas-supplying panel has a plurality of apertures, which are asymmetrically located, through which apertures gas is supplied. The driving device, coupled to the sensors and the gas-supplying panel, drives the gas-supplying panel to respond to the conditions sensed by the sensors, in which the gas-supplying panel can adjust the positions of the gas supplied through the apertures.
