split, turning vane, grille or diffuser. pipe must be a minimum of 6 ft. upstream from
elbows, grilles, etc. If temp. in duct is 60°F or lower
the distance should be 10 ft. If distance, as
mentioned, is not possible, a drain pan may be
required. If the air in the duct can not hold the
volume of steam, the only recourse is to reduce the
maximum output of the unit. If very short
absorption distances are required, a short
absorption manifold can be installed.
