Thanks for your question, NicoleN.
While this model is not a ventless dryer, it supports 4-way venting configurations (back, bottom, left, or right) to accommodate different installation setups.
For additional information, you may review the specification sheet below:

For the best fit and safe installation, working with a professional installer can help ensure everything is set up correctly.
