I havn't seen a Vulcan Continetal Boiler since the very early 1980's, so to hear that you have one in excellent condition is testiment to good old fashioned engineering!!. Now the Bad news, Long since obsolete, no burner parts availible i'm afraid, but boiler has done well for about 35 years, sadly your next boiler will be lucky to make 10!
