STEAM HOSES

To avoid these problems, remember one simple fact when running the steam hose: steam naturally flows up hill and
condensate naturally flows downhill. Run the steam hose or piping to avoid any kinks, sharp elbows, or low spots that could
collect or restrict the flow of steam to the distributor manifold, or the flow of condensate back to the humidifier. Support
the hose adequately to avoid sags. The following diagrams are provided as guidelines. Contact General Filters for unusual
installations.
IMPORTANT WARNING: Most operational problems are created by improper steam hose installation from the
humidifier unit to the duct distributor manifold.

IMPORTANT: The standard steam unit comes with 6 feet (1.8m) of steam hose. Maximum total length of rubber steam
hose is 3.65m (12 feet). The maximum total length of insulated copper tubing may be up to 6.1m (20 feet). The maximum
combined allowed length of steam hose and insulated copper tubing is 9.75m (32 feet). In all cases, minimize sharp bends and
elbows. Use two 45° elbows instead of one 90° elbow. Hose inner diameter 7/8" (22 mm); Hose outer diameter 1¼" (30 mm).
Additional steam hose is available GFI #7513 / CGF #GF-20-2.
