: 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° elbows. Hose inner diameter

NOTES:
• Slope piping up in direction of steam flow at 20% or greater, which means 1-1/2” per foot (65.5mm x 305mm).
• Slope piping down in the direction of steam flow at 5% or greater, which means ¾” per foot (20mm x 305mm).
• Max Length of rubber steam hose is 10 feet (3m).
• Height of p-traps must be greater than the duct static pressure.
