5.5.4 Steam Connections Checklist
Check the following to ensure that the steam connections for the humidifier have been installed correctly:
Steam Line
Observed all best practices?
Steam line exceed maximum length specified in
Table 6 on page 28
?
Minimum bend radius of 12 in (300 mm) for steam hose, or 5× internal diameter for rigid pipes
maintained?
Steam line sized correctly?
Backpressure in the line combined with duct static pressure exceed 5.5 in H2O (1.37 kPa), or
10 in H2O (2.49 kPa) with the optional Fill Cup Extension?
Steam lines run straight up from the humidifier steam outlet for at least 12 in (300 mm) before bend?
Steam line have a constant minimum upslope of 2 in/12 in (10°), or a constant minimum downslope
of 1/2 in/12 in (2°)?
Steam lines do not reduce in diameter except, if required, 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 or kink? Supported adequately? Any low points in line without condensate
trap?
If a steam hose is used, is it attached securely with clamps? Clamps secure without crushing steam
line?
Allowances for thermal expansion during operation, and shortening of the hose due to aging taken
into consideration?
Condensate Line
Local codes on drain water temperature requirements have been satisfied?
Condensate line from the steam distributor condensate port connected to the humidifier fill cup port,
or the drain?
Condensate lines installed at all low points, and at vertical transitions in the steam line?
Condensate lines in the steam line always connect to full-size "T" connectors?
Condensate traps have a minimum loop height of 8 in (200 mm) and installed at least 12 in (300 mm)
below the "T" connector or steam distributor?
All condensate lines have a constant minimum downslope of 1 in/48 in (1.2°)?
Maximum distance between the condensate traps on long runs is 15 ft (4.5 m)?
Condensate traps primed with water?
