Thanks Wang !.
1. Water around cover sealed the burner so the smoke and heat went into burner.
2. I did load a bin full of pellets, problem is fire went all the way to the top of bin , i guess you can call it a burn through, or total burn inside fuel bin.
3. I did manage to get the Temp up to 210 on manual, but my cooker is probably to big, no problem.
4. The contol unit acted strange, when on auto and pit temp showing 190 it suddenly showed 100 deg for about 2 min , then went to 174 for about 1 min. I had to turn unit off and back on to read correct pit temp of 190...when i say suddenly i mean pit temp was 190 then 100 then 174 no gradual change.. It did this on all settings of Single stage, and when all stages were loaded...Had Single stage at 1. 215 deg 2. 250 3. low alarm 175 4. high alarm 255..did this all afternoon while i watched ....
