NW Iowa
There is a spot I believe on the back by the left side of the outlets. I skipped over this series but my dad had one. Can't quite remember where it was. Thinking of a plug up on top of the rear end someplace.
I looked in the parts book, looks like there should be a plug you can remove and put a pipe fitting in.
