Humidifiers and Dehumidifiers - Can furnace mount hum. be installed on duct?

Hi - For Christmas I received as a gift a new Kenmore Mod. #93806 18 gal. furnace mount humidifier as the old duct mounted 25+ year old said I quit a couple years back.The old one was basin type with ceramic wheels that turned slowly rotisserie style attached horizontly to the warm air plenum and powered by 110V outlet on furnace when the furnace was running. As it's still in the box I didn't want to open it and try to install it if for some reason it wouldn't work. Thanks for your help.

Yes, it can be mounted where the old one was... YOu may have to cut the hole bigger or some patching to match the new hole.

I see this is a reservoir model, reason for this?

I suggest the flow though type.

Thanks for your reply Jay - My concern would be that instead of mounting it vertically I would have to mount it upside down hanging from the duct. I don't know if this would cause a problem because of the of the reservoir. As I mentioned this was a gift and I would like to use it if possible. I know General Aire and Scuttle make duct units which would be the way I would go if setting this up would not be feasable. Thanks again

The new unit will not work this way.. it has to be hooked up on the side of the duct work.

You can patch up the old hole, and cut a new one in the duct work .
