We had one when I was a kid, in the 70’s. I can remember my dad buying the kerosene at the gas station. Is that normally where one bought kerosene?
Kerosene comes in a couple forms/grades. The "at the pump" grade is the least pure and should NEVER be used for unvented indoor heaters even with the window open. People did it all the time as they were/are unaware.
