I too need help fixing my heater. I've downloaded 2 manuals, and some generic instructions for replacing the wick but they don't solve my problem.
In step 8 of the manual it says remove the wick adjuster assembly, presumably by simply lifting it up after removing the 4 wing nuts. It won't lift up, it wont pry up, and I'm afraid of bending or breaking something to force it further, than the inch I've gotten it. The video instructions link someone gave wont load for me. Also the adjuster knob wont turn. Can this problem be fixed or do I have to junk it?
