Open drain required.
Locate air gap only in spaces with adequate temperature and air
movement to absorb fl ash steam; otherwise, condensation may form
on nearby surfaces. Refer to governing codes for drain pipe size and
maximum discharge water temperature.

– 2"/ft (15%) when using steam hose
– 1/8"/ft (1%) when using tubing or pipe

HEADER OUTSIDE OF DUCT, HORIZONTAL AIRFLOW
1. Mark and cut holes in the ductwork for the dispersion tubes. Use the
L-bracket as a tem plate to mark the holes on the duct floor.
2. Temporarily, loosely suspend or support the header below the final
location. Vertical balance point of the dispersion tube length dictates
where the header should be suspended or temporarily supported.
3. Mount the dispersion tubes to the header with the slip coupling or hose cuff
(provided).
• When installing slip couplings for 1½" (DN40) dispersion tubes, take
care not to shear the O-rings.
• Set the slip coupling on the header stub or dis per sion tube so the O-ring
is resting on the face of the tubing.
• Rotate the slip coupling as you push it onto the tubing.
• The O-rings are lubricated at the factory. If additional lubrication is
necessary, DO NOT use a petroleum-based lubricant.
4. Position the flange of the L-bracket so it is upstream of the tubes when the
assembly is raised and fastened into po si tion. Fasten the L-bracket to the
end of the dispersion tubes with the provided bolt, lock washer, and flat
washer.
