OPERATION All coal fires start with a wood fire. Coal is more difficult than wood to ignite and requires a good bed of hot coals for ignition. Coal firing steps are as follows: 1. Start a wood fire in the conventional manner using newspaper, kindling and split wood. Establish a good shallow bed of coals. 2. Add an even layer of coal 2-3 inches deep on top of the wood coals. Wait until this layer is ignited and burning (look for telltale blue flame) before adding more coal in a level bed. 3.
