Topics Covered in this Chapter
▪ Duct Specifications
Duct Specifications
The number of duct sections and free-air openings will vary depending on the diameter and capacity of
the dryer.
1. The number of ducts on the diameter will be equal to the number of duct elbow packages
(GT4-1535) and will represent the number of grain columns that support the duct work.
NOTE: Space the ducts as evenly as possible around the diameter of the dryer.
2. The required number of 40” duct sections tall represents the number of straight duct section
assemblies (GT4-1533) that are stacked on each other to give height to the heat reclaim ducts.
3. In order to provide adequate airflow, all 18” free air openings must be removed EXCEPT for the
number that is listed in the table; all 24” louvered doors will remain in the dryer.
NOTE: For a stainless steel heat reclaim package, add "-SS" to the end of the base number.

3Heat Reclaimer Starting
Locations
Topics Covered in this Chapter
▪ Heat Reclaimer Starting Locations
Heat Reclaimer Starting Locations
These starting locations are the where the ducts will pass through the grain column and where the
enclosure roof flashing is installed. It's advised to install the duct work beginning at the duct pass-thru
point, and work your way up. Once the duct work is installed, begin at the enclosure roof flashing start
point and work your way down.
What You Should Know
The duct pass-thru window MUST pass through the grain column BELOW the divider hopper. The
pass-thru duct window will split the sidewall sheet horizontal seams, therefore you will need to cut the
sidewall sheet above and below the seam. For the duct and enclosure starting locations, reference the
image for your dryer model in the following illustrations in this chapter.
1. Cut a half-circle out of the bottom side of the top sidewall sheets where the duct pass-thru will be
installed.
2. Cut a half-circle out of the top side of the bottom sidewall sheets where the duct pass-thru will be
installed.
3. Install the enclosure roof flashing on the horizontal seam as indicated in the enclosure starting
location illustration for you dryer model.
