The rubber vapor hose carries the steam to the dispersion
tube and condensate back to the unit tank. It must have an
8% (1” per foot) pitch back to the unit. Support the vapor
hose so that it maintains proper pitch when the unit is in
operation.

"Y" CONNECTOR
If you must split the discharge of one steam outlet into two
ducts with the same static pressure, a “Y” connector is
available from the factory. The length of vapor hose after
the “Y” connector must be the same to ensure equal steam
distribution.
