Thank you for having the manual I needed for an older model Aiwa stero I had found on Ebay --- I wanted the Aiwa because I had tapes and cd's but I did not have a manual as to how to operate the system... I found what I needed and it has enabled me to set the system up for my enjoyment.
I wished detailed information of the JBL S310 and here I found it! Very happy with the service from this site!

Replacement of the nozzles Every appliance has spare nozzles for every gas. The whole of every nozzle is marked in microns on the nozzle. For changing the nozzles: 1. Remove the pan support; 2. Remove the burners; 3. Using a socket spanner 7 unscrew the nozzles (fig. 23) and replace them with those required for the type of gas in use. Put in place the burners and the pan supports. Adjustment of minimum level for the hob burners The burner is correctly adjusted when the flame is stable silent and goes out without any noise. When changing the type of gas check that the minimum level is correct. The air admission is correct when the flame is about 4 mm in length. The top burners do not need adjustment of primary air. Check that, turning the knob quickly from the maximum position to the minimum one, the flame does not go out. Flame adjustment To adjust the minimum level: â¢ Light the burner â¢ Turn the knob to the position of the minimum flame; â¢ Remove the knob; â¢ Unscrew or screw the by-pass screw (below of tap shaft) until a regular small flame is reached. â¢ For LPG screw completely the by-pass screw. Reassemble the parts following the same procedure in reverse. Check that, when turning the knob quickly from the maximum position to the minimum one, the flame does not go out. fig. 23
