Just today I got my Brand New 48 patio. Was in the process of seasoning tonight and all was going good until I sprayed it out. Noticed my temps dropping so I added another split. Now I can't seem to get the temp about 150. Not sure if I didn't start with a big enough bed of coal or what. I started with 5 splits, let the smoker get to about 290 and then started trimming down the pinwheels. All was good for about 2 hours and now I can't get the temp up. I am not sure what the issue is. Any help would be greatly appreciated.
