The main conduit includes an inlet portion (12) and an outlet portion (14) that form a passage for supply of a first gas in a forward direction. The inlet portion is adapted to receive a supply of the first gas and deliver the first gas to the outlet portion (14). The gas conduit (20) has a first end (16) and a second end (18) that form a second passage for supply of a second gas. The first end (16) of the gas conduit (20) is adapted to connect to a second gas supply, and the second end (18) is adjacent the outlet portion (14) of the main conduit and delivers the second gas into the main conduit such that the second gas is directed to flow in a forward direction.
