My concern was for not. It worked great just the way it is. Put a chunk of wood in and set for 200. Came up to temp in very little time, then let it go at 200 for about 6 hours, consumed the wood and held temp great. Then put in a 6.2 pound pork butt. Used 4 oz. of hickory, set at 250. Smoker came up to temp quickly and maintained temp very well. Meat reached 195 in 8 hours. Took it out, wraped in foil and towel and put in a cooler to rest until morning. Took it out this morning, still hot, pulled off the fat cap and bone and the meat pulled apart perfectly, was super tender and moist. Awesome result for the first time.
