I am thinking of buying a Hotpoint HAG51K cooker but I use only LPG. The product info for this model says ‘Converter not supplied’ but other websites say it IS AVAILABLE. I have contacted various suppliers to check if they have the correct LPG converter but that ALL say “contact the manufacturer”. So I called Hotpoint and after a long chain of questions thay say they THOUGHT they do a converter but I have to BUY THE COOKER FIRST before they can help me!!! Are they mad!! Anyone with any suggestions please for this HAG51K model??
