Hi all, was wondering if someone could tell me what each of the dip switches does on the PB105?? I know they control the amount of pellets on startup (at least some of them do) but I would like specifics. I am trying to have the least amount of pellets possible fed in so that they don;t smolder so much prior to startup. I notice quite a bit of smoke when mine starts up from a cold or colder start. Thanks for any help.
