Here is an update.
In the instructions they suggest wood chips, yet I had none. They also mention pellets so I tried pellets, but not again.
First run it produced huge amounts of Thick White Smoke (TWS) and never burned hot enough to get Thin Blue Smoke (TBS).
First run I realized I started the coals in the ash base vs the bottom of the smoke generator.
After the first run I watched a few videos, read some write ups and tried again.
Second attempt:
coals started in a chimney, then put on the grate of the smoke generator and got it good and hot with the air pump going. I added about a cup of pellets. It went to TWS again and 30 mins later still was heavy smoke.
<WARNING> I removed the lid and it was like a Genie escaping with whoosh of blue flame. do this with caution...
I let it burn with the lid off for a while, and then returned the lid to the smoke generator to see if the smoke would stabilize. It did not. TWS returned and did not clear. I removed the lid and let the pellets torch out.
Second Attempt, part B:
There were still pieces of coal white hot at the bottom of the smoke generator. I did not have any wood chips, but I found two small chunks of maple and put them in the generator. I let them get started, and they begin to flame, then I put the lid on and put the pump on high. Within 5 to 10 mins ( I didn't time it or take pics as it was dark) the smoke thinned.
BGE top vent removed so it was wide open not trapping any smoke and smoke was coming out the top, just not massive amounts like the pics above. The two small chunks burned for about an hour and when opening the lid there was a fair amount of smoke inside, but thinner smoke. It was hard to gauge the color as it was dark.
I put two frozen salmon patties on the grate and smoked them for about 30 mins, and then finished them on the kettle.
Conclusions so far:
Hot coals are necessary to get things started.
Pellets make thick white smoke and lots and lots of it.
Wood Chunks seem to do better.
Third attempt will be with wood chips.
I also need to find the best place to drill into my pit boss so I can try it there.
Also looking at how I might modify my old grey 22 inch kettle to handle the smoke generator.
