as long as it is flow throgh it is correct. I always mount the humidifier on

in the return and not on the heat exchanger.

Humidifier Connection Question

Thanks. Does this not mean though that the return air mixed with
water vapour from the humidifier is then fed through the intake fan
and blown over the heat exchanger ? You would lose most of the
moisture this way right?

Lose it how? The moist air gets heated, but it still has exactly the
same amount of water in it, as there is no place for the water to go.
There are two types of humidifiers. The type you have is a bypass
model. It bypasses, or short circuits some of the air from the hot air
plenum through the humidifier and into the return plenum. That allows
the unit to be cheaper, as it does not need a fan. The other type has
a powered fan and only goes into the hot plenum. Take a look at an
Aprilair 760, which is a powered model.

The disadvantages to the bypass model are that you do lose some blower
capacity, but that probably isn't an issue in most heating systems.
They usually have some sort of sliding piece of sheet metal to allow
the bypass to be blocked during summer cooling. Whether most people
remember to move it is another question. The other possible
disadvantage would be if passing moist air over the heat exchange could
shorten it's life. I don't know if that is a potential issue or not,
but usually exposing steel to a moist environment is not a good idea.

Thanks guys.
