Thanks for the info, IdahoMike. To answer your question, yes, I have read the manual - it did not address the subject of chips.
My purpose of asking about chips is that, cooking Jerky at 200℉ with hickory chunk (2 oz) in the smoke box I experienced negligible smoke. Yes, June in Phoenix Arizona EVERYTHING is dry! Chips being smaller with more surface area would probably work better in this case. My question was if CookShack determined any issue with using chips instead of chunks.
