chunks on gas smoker?

[Jerod Broussard]

I make my chunks touch the flame and BURN. Gives the cleanest smoke you could ask for.

I use nothing but chunk and solid wood in my gasser. Work perfectly.

So my masterbuilt is made for chips and i think it even says in the manual (though i am not 100% sure since i don't keep the manual at work) not to use chunks. however my father in law gave me a cross section of a hickory tree trunk and it would be a lot easier for me to chunk it rather than chip it. so my question is: do you think it is fine to use chunks in a gas smoker and if so do i need to do anything to these chunks such as wrapping in foil to reduce air? or will the chunk just smoulder for a little while and i would get way more use out of chipping it?
