It should be taken up by Ebay, but Ebay feels that by saying that the responsibility of any sale is on the seller, they are exempt from any legal reaction.
Of course, this does not exempt them from moral responsibility if someone sells an appliance that explodes and destroys a family in their living room.
There are many problems with second hand gas appliances. the Filaments may be 'burnt out' and ready to crumble. This will cause a flare up of gas fed flame. If the appliance has been stored for some time, wasps will make nests in the gas lines and the gas jets will be obstructed, and my suddenly open to create a flash that will burn any leaked gas, which can be close to an explosion. Gas bottles do not explode, they will release gas through the safety valve, and although the sound adn sight is dramatic, an explosion does not normally occur. Faulty gas appliances usually leak excess gas into an enclosed area until it is ignited by a spark source, and then you have the deadly explosion.
I would purchase a gas appliance from Ebay IF: the inspection certificate was provided by a registered gas fitter, and I would expect to pay, via the price offered on Ebay to cover that inspection.
