I am finishing my basement and want to move my humidifier to the opposite side of my furnace so it does not get blocked in. Is there anything that would stop me from doing this? There is enough space on the other side of my furnace but outside of that I don't know what the restrictions may be.

The humidifier should be on the positive pressure side of the p!enum, the hot side. Doesn't make much difference as long as there is good airflow.

Depends on the type of humidifier you have. Do you have a brand and model? Some can only go on the hot plunum. Are you switching from the hot to the cold plunum or just another side of the hot plunum?
