STEAM LINE INSTALLATION
GUIDELINES
1. Nortec steam hose should only be used on
short steam runs below 10 feet.
2. Ensure that no condensate produced in the
steam line will remain trapped. Steam
naturally flows upward and condensate
naturally flows downward.
3. See material recommended for use in the
chart below. To eliminate the metal
corrosion, Nortec does not recommend the
use of steel piping.

Description
Please note that options shown in a bold-italic font requires
that reducers be used at both ends. These extra large sizes are to
allow for better condensation removal in long steam runs. These
sizes will not permit you to use hose coupling to connect your
self to either humidifier or distributors.
