The polytube adapter option is designed to adapt this blower-
type heater for use with polytube ductwork. The use of
polytubes for air distribution is common in greenhouse appli-
cations and some industrial applications. A polytube distribu-
tion system delivers warm air to a specific area, reducing the
need for complete area heating. The polytube adapter is avail-
able in three installation designs making it adaptable to many
applications and building structures.
