The ignition system on our old (probably 20 years) gas hob has failed and we've been using matches. I've seen some in shops that look about the same size, so I'd expect to be able to disconnect the old one, unscrew it, and drop the new one in. From the last time I rummaged around under the oven (which is under the hob but completely separate from it, and not gas-connected), I think it the hob has a flexible gas line coming down to a bayonet or similar fitting. Is reconnecting this suitable for a DIY job? Are the fittings likely to have changed over the years?
Also, I noticed that most --- but not all --- of the ones I've seen in shops say "flame failure" on them. Are they not all required now to cut the gas off if the flame gets blown out?
Thanks, Adam
