Kerosene heater---No kerosene?

Some of these units vary. You can run no1 Diesel. DO NOT run no2 Diesel unless you like a lot of smoke and fumes, or the unit specifically states this on the label.

If you go to a "one diesel pump" store it's going to be no2

For example, I have one powered "torpedo" which specifically lists either Kero or no1 or no2 Diesel.
