MM, which model Yoder is that and can you apply smoke without heat ?
It is a YS640.
To smoke with out heat just don't fire up the smoker but use it as a smoke chamber using a tube smoker with smoldering wood pellets to apply smoke with no heat.
Total cook time was about 5 hours. Ran 150º for a few hours and then bumped the temp to 170º till the meat sticks had an internal meat temp of 155º.
