OK How to light a Bialaddin lantern ( or most normal Kerosene lanterns)
1. Select the lantern ( this can be more difficult than it seems)
2. Ensure the lantern has about 3/4 of a tank of fresh Clean kerosene ( paraffin) do not over fill the tank.
3. Replace the tank lid and ensure the air screw is loose. This is important if it's done up the lantern will start to pressurise before its preheated and you'll start to burn unvapourised kerosene which is messy and soots up the lantern glass
4. Fill the preheater cup with Methalayted Spirits
5. Ignite the Meths and allow the burning meths to warm the vapouriser tube
6. When the meths is starting to burn down close the Air Screw in the Tank Lid
7. Then give some gentle strokes of the pump
8. The lantern should 'pop' into life...
Add more strokes of the pump to get the desired light output...
You regulate the light output by releasing air from the tank with the Air Screw.
The Knob on the lantern just controls a pricker needle to clean the jet.
Don't use this to try and regulate light output you'll ruin the needle and jet in very short order...
Hope this helps
