Can trusteam be installed in return duct with remote kit if its not possible to put it in the supply

Hi,
With the remote kit all you need is a small hole to get into the supply duct. That should be possible in most any situation.

The problem you will have if you install it into the return is that the steam could cause corrsion inside the furnace, and or cause problems with the blower motor, from the extra moisture.

If I would chose to install in the return duct I would want at least 6-10 ft. of duct and an elbow before the furnace to assure that the air fully absorbs the steam before it gets to the furnace. I would then monitor the blower compartment to check for moisture building up in there.

If you do not have it here is the manual that shows the prefered installation and how the remote works.
