Steam Output
Installation
Use only high quality, low pressure steam
hose which is able to withstand steam
humidifier temperatures.
The steam hose alone may be used for
distances up to 6 ft. If the distance from the
humidifier to the duct is greater than 6ft.,
insulated rigid copper tube should be used,
with sections of steam hose for connectors.
All steam lines must be pitched so that
condensate which forms in the lines will be
drained back to the steam generator or to a
separator & trap in the steam line.
a. Provide vertical rise at least 20 in. before
bending the hose to horizontal.
b. The steam hose should be rigidly suported
to promote rapid draining.
c. Steam hose (radius of bend should be 30
in. Minimum.)
d. Duct work.
e. Obstacle.
f. A condensate separator and trap is needed
at this point to drain condensate.
g. 8 mm condensate hose. Fill the
condensate hose trap with water before
starting the humidifier to prevent steam
from escaping.
h. Humidifier height (see page 3. )
Number of steam outlets:
RTH 5 to 20 = 1 outlet 60mm ( 2.4 ‘’)
Reducer may be used (see page 9)
RTH 30 to 50 = 1 outlet 60mm (2.4’’)
RTH 60 to 100 = 2 outlets 60mm (2.4’’)
The RTH humidifier can work with duct
pressure up to 10’’ of water column.
