Query: No bottom vents

Unlike the Smokey Joe silver, the gold model does not have vents on the bottom under the coals. The vents on the gold model are on the sides above the coals and are held in place by the carry handle frame. This location does not allow for proper air circulation as in other Weber charcoal grills and I had trouble getting the coals hot enough to cook even after letting them burn for a half hour. I had to transfer the food to my gas grill to cook 4 chicken breasts. Placing the cover on the grill seems to extinguish the coals. The coals were a brand new bag of Kingsford and they were dry.
