Distributor Mounting Instructions
Sheetmetal Duct:
Make a 1-1/4” hole in the duct at desired location. Insert duct
distributor and secure with self tapping sheetmetal screws (sup-
plied by others).
Fiberboard Duct:
Make a 1-1/4” hole in the duct at desired location. Insert duct
distributor and mark the four holes on flange. Drill (4) ¼”- holes
at marked locations. Cut an access hole in duct and install the
enclosed tee nuts from the inside of the duct. Fasten distributor
with enclosed ¼” bolts.

Steam Distribution
Blower Version (6000-1,2)
The 6000 Series Steam Humidifier with the built-in blower pack
should be mounted a minimum of 18” from the ceiling. There
should also be 5 feet of horizontal clearance in front of the unit
to prevent steam from condensing on obstructions (See Figure
1). There is an adjustable louver to adjust the direction of the
steam plume.
WARNING!
Do not adjust this louver to extreme angles as it will re-
strict the airflow causing condensation to form around
the steam distribution manifold.
WARNING!
Locate away from areas where people can walk into the
steam path.
Ducted Version (6000-3,4)
Herrmidifier supplies a stainless steel duct distributor for inject-
ing pure steam into the duct. This can be installed in the bottom
or the side of the duct (See Figure 5). When installing in the side
of the ductwork make sure it is positioned to allow condensate
to drain back down the steam hose. The duct distributor pipe
has a built-in pitch to allow condensate to drain back into the
hose. The hose must be installed with a minimum 8% (1” per
foot) pitch back to the humidifier to allow condensate to drain
back to the steam cylinder (See Figures 5 & 6). A minimum of 5
feet downstream clearance before any bends or obstructions is
recommended for most applications (See Figure 2 ). However,
different psychrometric conditions may require greater or lesser
steam absorption distances. A minimum duct temperature of 60°
F is recommended. Temperatures below this may cause con-
densation to form in the duct. Lined duct may be used if the
thickness is 1” or less.
