Multiple Manifolds – See Page 7 for required pipe sizes and dimensions of manifolds with pipe adapter.

Piping Multiple Manifolds – Figure 9-3 below shows the standard installation of reduced size manifold. Note the steam

jacketing is trapped separately and the steam discharge is into a tee, not a cross. A cross will

cause uneven steam distribution from manifold to manifold.

Humidifier discharge piping, even with reduced sized

manifolds must be as shown.

When same size manifolds (as the

separator) are used, the piping can

eliminate the drain trap from the

manifold jacket. Note that steam now

discharges into an elbow, not a cross,

and that the manifold steam jackets

are not trapped separately.

Note: The humidifier steam inlet is

below the bottom manifold. If the

bottom manifold is below the

humidifier inlet, piping should be as in

Figure 9-3.

Note: When steam supply pressure is

less than 10 psig and total length of

manifolds is greater than 20 feet, trap

manifolds separately as shown in

Figure 9-3.
