I'm looking for information to replace a Combustioneer CV 50. It has Will-Burt on the back. It burns #2 Kerosene (heating oil) and has a flue. It still turns on, but I've been told it doesn't work correctly. Is there something newer that could replace it? Something that still burns #2 kerosene? I'm looking into this for someone else-I don't know much about it. Any help would be appreciated.
