Hi there.
Looking for professional advice regarding installing a steam humidifer (Honeywell TrueSteam HM512VPIAQ).
Gas furnace with heat pump - dual energy.
On my vertical furnace duct, I have 27 inches of clearance between the top of the A-coil and the top wall.
-The installation manual says "ensure proper clearances from A-coil"
What are the proper clearances? Does it just mean to make sure to not fire the steam into the A-coil, or is there a certain distance above it that I need to be?
-The manual also says "minimum 24 inches from downstream open duct air space (needed to prevent condensation)"
So is it safe to say that I can install the nozzle at 3 inches over the A coil and 24 inches below the top wall?
Obviously, I don't want condensation to cause water to pool in my furnace (probably ruining it...)
Advice please!

Thank you.
