I see no venting on the outside that would allow the cap to breath. If this is the correct vent location, does the cap maybe vent to the attic space?
As someone else noted I'd be calling the manufacturer's support line for clarification. My guess is it needs to vent all the way to the outside. I suspect that the placard really means "There is no interior wall structure here so you can safely drill a big hole."
Our Splendide 2100XC vents to the outside and that thing tosses a fair amount of lint on the exterior. That would be a problem in an enclosed space like inside an end cap, especially with the high humidity of the exhaust air.
The newer 2100XCs do not have a removable, manually cleanable lint filter. They have some kind of automatic lint filter backflushing mechanism that flushes the majority of the lint out the waste water drain (into the gray tank).
But there is an undocumented cleaning procedure you need to run occasionally that gets the remainder of the lint out or eventually you can experience an overheat shutdown or significantly longer drying times. We had the overheat shutdown error code and Westland Support sent us the cleaning procedure, which fixed the overheat problem and returned the original drying performance.
