28.Optional Polytube Adapter - Options CD6, CD8, and CD11 (Blower Models only)

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.

WARNINGS: This adapter is to be used only on units equipped with a blower. At no time should the free area in the polytube be less than the listed minimum. Failure to comply with these warnings could result in severe personal injury, death and/or property damage.

The polytube adapter option package does not include polytubing. Polytubing can be obtained from a supply distributor such as FOF Products, Inc., P. O. Box E, 1505 Racine Street, Delevan, WI 53115; ACME Engineering Co., P.O. Box 978, Muskogee, OK 74402; or any local greenhouse supply distributor. Some local code authorities require the polytube material to be a listed mate- rial. Consult code authority having jurisdiction and the polytube supplier to determine the appropriate polytube material and rec- ommended methods of suspension.
