5.5.3 Steam Connection Checklist
Check the following to ensure that the steam connections for the humidier have been installed correctly:
Steam Line
Observed all best practices?
Steam pipe sized correctly?
The steam line does not exceed maximum equivalent length listed in Table 12 on page 30?
Long radius elbows (for rigid pipes) used?
Backpressure in the line combined with duct static pressure does not exceed 6 in H2O (1.49 kPa)
for compact units, or 10 in H2O (2.49 kPa) for full-size units?
Steam line runs straight up from the humidier steam outlet for at least 12 in (300 mm) before bend?
Steam line has minimum upslope of 10°, or minimum downslope of 2°?
Steam line does not reduce in diameter except at the steam distributor; and condensate line installed
just before the restriction?
Steam lines do not merge except at the steam distributor through a Nortec adaptor?
Steam line does not sag?
Steam connections secured with clamps? Clamps torqued adequately?
Allowances made for thermal expansion of rigid pipes, and shrinkages of steam hose?
Steam line insulated over its entire length?
Condensate Line
Local regulations on drain water temperature requirements have been satised?
Condensate traps installed at all low points, and at horizontal-to-vertical transitions in the steam line?
Condensate lines in the steam line always connect to full-size "Tee" connectors?
Condensate traps have a minimum loop diameter of 12 in (300 mm) and installed at least 12 in
(300 mm) below the condensate "Tee" and the steam distributor?
All condensate lines have a minimum downslope of 1.2°?
Condensate traps primed with water?
