NOTES:
• Slope hose up in direction of steam flow at 2 in. per foot;
• Slope hose down in direction of steam flow at 3/4 in. per foot;
• Maximum length of remote steam hose is 20 ft.
• Height of P-traps must be greater than the duct static pressure. (Typical 3 in.
will suffice.)
• Minimize sharp bends and elbows.
• Insulating the remote hose in unconditioned spaces will sustain efficiency better
than not insulating the hose.
