1 Remove the casing.
2 Open the airtight chamber.
3 Unscrew the gas coupling A on the air/gas mixer.
4 Replace the injector in the mixer with the one contained in the conversion kit.
5 Refi t the coupling A and check the connection is gastight.
6 Apply the sticker, contained in the conversion kit, near the dataplate.
