If I m not mistaken, this heater uses a modified Primus burner, mods being supposedly to allow burning diesel instead of kerosene. I built my own heater years ago using such a burner, and it was a PITA in many ways. First, the requirement for preheating... fill the built in cup with alcohol, light (if it hasn't slopped out) and wait just the right period before opening the valve and letting fuel
in. Of course, you had remembered to pump
up the pressure in the tank, hadn't you? If not, damn thing went out with a belch of soot. Often the diesel simply wouldn't vaporize well, and it smelled, well, diesely as it burned, smoking away. It did a lot better on kero, and eventually that's w hat I did.
Anyhow, compared to the various pot burners (older Dickensons and FAb-Alls)it was a mess. We've now got a Fab-All and it is a far better unit.
