Its like a scavenger hunt. Bigfoot provides a bunch of spare parts with their units but hides them in out-of-the-way places. So far I've found numerous screws, a hydraulic strut (for upper cabinet door), and a furnace vent. I spotted the latter in the bottom of the bathroom cabinet 10 years ago but couldn't get it out until last year when I pulled the water heater to replace it.
As to the original question, I bought my unit new and it too has the removable panels on the bottom. I'd like to ask a question of my own on that. For those who have removed it, what did you use to seal when you replaced it?
