* Developed length equals measured length plus 50% of measured length to account for fittings. • DriSteem recommends 6' (1.8 m) maximum steam hose length pitched at 2"/ft (15%) toward humidifier. Steam hose tends to sag if not supported for its full length, which leads to collecting condensate and system pressure issues. Tubing sags less and can allow for 1/8"/ft (1%) pitch with longer runs. -
