It looks like the firebox on the Caldera Cone is huge. If you have nice dry wood top lighting is pretty easy. You can stack it mostly vertical, thickest fuel at the bottom to smallest twiggies at the top. I will usually light my tinder and add just a little wood on top after. I havent really looked at the base of the CC closely, but good airflow is critical at the bottom and at the top. Im sure it should work fine.
Here is a video a little larger stove but using the same concept to boil over 4 cups.
If you have wet wood, it is very hard to top light. No Big deal. Use really good long burning tinder and light it from the middle or bottom.
