* Based on total maximum pressure drop in hose, tubing or piping of 5" wc (1250 Pa)

** Maximum recommended length for vapor hose is 10' (3 m). Longer distances can cause kinking or low spots.

*** To minimize loss of capacity and efﬁciency, insulate tubing and piping.

† Developed length equals measured length plus 50% of measured length, to account for pipe ﬁttings.
