Consider adding an outside air supply to
your furnace air return duct.
Not exact matches
This humidifier comes with a humidity control that is easy to use, and you can mount it on both the warm
air and
return air ducts on your
furnace.
Please make sure that the vents are secured to all
air registers and
returns that lead to your
furnace.
If the
air return is in a
furnace room, combustion gases can be sucked out of the flue (backdrafting).
In a gravity
furnace,
air is circulated by gravity, relying on the natural flow of warm
air up and cold
air down; the warm
air rises through ducts and the cold
air falls through ducts that
return it to the
furnace to be reheated and this completes the circulation cycle.
When the
furnace runs, this arrangement will draw dry outside
air into the
return duct of your
furnace.
Replace
furnace and
air return filters (an important task year - round!)
I know to change the
furnace filter on a regular basis but a filter for the
air returns is new to me.
