No. The absence of a wall exhaust does not remove the manufacturer's requirements for location, clearances and room conditions. Different drying technologies still have installation limits.
Understanding this situation
A cupboard or tight fitted space must suit the exact appliance. Blocking openings with laundry, stored products or improvised panels can change its operating environment, even when there is no exhaust hose to inspect.
A useful next step
Check the documented arrangement and keep permitted openings clear. Do not remove fixed cabinetry or panels yourself to create airflow. Report an unusually hot enclosure or moisture change and establish appropriate access before a repair visit.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
