Any change must comply with the exact appliance's installation instructions and be carried out appropriately. An improvised route can restrict exhaust or discharge moisture where it should not go.
Understanding this situation
Length, bends, materials and outlet arrangements can matter, but there is no universal measurement suitable for every dryer. A performance complaint should not be solved by detaching the hose and running indoors.
A useful next step
Describe the existing route and recent alterations to the service team. Use competent installation advice for changes. Stop use if exhaust appears blocked or the dryer overheats, rather than trying progressively different makeshift hose arrangements.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
