I'm using my chargriller duo for first time. I tried smoking just doing the charcoal side but temp got too hot (I souad hard time keeping it under 300 so it tasted good but was sliceable I got a chimney to keep fire going and the side box. I have both vents..into SF and vent into grill part open but I can't get temp up to 225. Also, I put my chimney full of lit coals over more charcoal wood mix and it is looking really ashy. When do I put in more? Do I havejust stick pieces of charcoal and wood on too or light another chimney and pour it in? Ive seen some articles about mods I may have to have my hubby help me understanding that after this is done. If it is food safe at 200 I'm cool with that even if it takes longer but it's only been on grillhour and a half
