Why is there smoke coming into my room?

All PelPro appliances are designed with seals that are tight and designed to seal the door completely when it is shut. If smoke is coming into your room, it is most likely due to the venting and/or the ambient pressure in your home. You may want to check all the venting joints and confirm they have been sealed with high temperature silicone, especially the connection where the venting (chimney pipe) meets the unit. This can also sometimes occur if the appliance is not cool before loss of power or unplugging.
