charcoal/oil is the simplest method to light coal. The spot and the location should be safe t light the coal and take expected outcome from the consumption of coal. Newspaper and very dry wood scraps are also a good decision.
So far the easiest way Ive found is a charcoal briquette burried in the coal and a heat gun. Aim the heat gun at the briquette for five minutes, turn the fan on, and you have fire!!
