I recently purchased a 1987 hunter 31 with a Force 10 kerosene heater that is not working and missing some parts including control knob, burner wrench and clean-out tool. Force 10 does manufacture these anymore and reportedly does not have spare parts. They sold the line to Dickerson. I do not want to replace it. 1) can anyone recommend where, and 3) any reason why I should NOT refurbish it? Appreciate your input.
