On the location of this humidifier unit, does it really matter exactly where it's put? The ONLY spot availabe on my unit is on the left side for the
return air entrance of the unit, on the left duct, just as the air is returned before the blower fan compartment, which is under the burners to the right in the main furnace unit. No other location allows for room due to the size of the unit. Here is the link to give you a better idea. The duct to the left is the return duct.

I have about 28 inches height (from floor to elbo) to play with. The unit is 14 inches tall. Do you see a problem with about 4 inches room for the drain tubing at the bottom of the humidifier? I might have to jossil it a bit as I need clearance to pull the front cover and service/replace the filter pad during yearly maintenance. Not an ideal place, but I have no other options due to the size of this humidifier and allowable space for clearance.
If this is critical as far as affecting humidifying efficiency, should I look for another smaller style/size that will fit above the furnace output?
Thanks!
