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' of horizontal
clearance in front of the unit to prevent stem from
condensing on obstructions (See Figure 1). There is an
adjustable louver to adjust the direction of the steam
plume.
DUCTED VERSION (6000-3,4)
Herrmidifier supplies a stainless steel duct distributor for
injecting 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 degrees F is recommended.
Temperatures below this may cause condensation to
form in the duct. Lined duct may be used if the thickness
is 1” or less.
Distributor Mounting Instructions
Sheet metal Duct:
Make a 1-1/4" hole in the duct at desired location. Insert
duct distributor and secure with self-tapping sheet metal
screws (supplied by others).
WARNING!
Do not adjust this louver to extreme angles as i
t
will restrict the airflow causing condensation to
form around the steam distribution manifold.
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.
WARNING!
Locate away from areas where people can walk
into steam path.
