Last week I bought a Char Grill SNP, yesterday I seasoned the grill and I had no trouble keeping the heat up (I was using both fire box and inside grill, also before MODS, Extended chimmney and baffle) today I was having trouble keeping the temp up just using the fire box, I finally took a grate out and started a fire in the main grill. I didn't want to loose a lake trout and beef roast. Temp. is up now and all looks good has anyone else had this problem? I am new to the forum but I am a pretty good cook and have been cooking along time, I understand the principles but the only smoking I have done before was on a little chief electric.
