Can the CV-353 be run without venting via muffler or is it a closed system

The NuTone CV350 is not a closed system and cannot be run without proper venting. The exhaust should not be vented into a wall, ceiling, or concealed space in the house. It must be vented to the exterior using mufflers and appropriate exhaust vents such as Model 393 Wall Caps or louvered exhaust vents.
