I have a gas forced hot air furnace with an Aprilaire 560 Humidifier. I would like someone to verify that the humidifier was installed correctly and if so, explain how it works in this configuration.
The unit is installed on the return plenum via a square hole in the plenum. The unit sits in front of this opening. There is a 6" round duct that connects the left side of the unit to the supply plenum of the furnace.. In this round duct there is a vent lever to control air flow. During winter this vent is open
So if I understand this correctly... as warm air leaves the furnace "SOME" air is forced through the humidifier via the 6" duct. it passes through the water panel back into the furnace via the square opening in the return plenum where it is re-heated and sent back through the supply plenum where some gets returned to the house while some gets sent back to the humidifier.
Am i missing something ? this just seems inefficient.
Thanks Ollie
