External load-result checklist
Enter results from the external load-calculation program, document field constraints, and identify when a technical review is needed.
Load Calculation Results
Entered from an external load-calculation program. GreyModule does not calculate or modify these results.
Duct trunks
Enter width and height in inches. Add every major trunk that serves the home; GreyModule uses the combined area for an approximate capacity estimate.
Guide reference: 80 sq. in./ton hard ducting; 113 sq. in./ton flex ducting; 144 sq. in./ton return grilles.
Registers and return grilles
Supply-register rows are record-only. Return-grille rows use the guide's 144 sq. in. per ton reference in the approximate capacity calculation.
Field observations
Enter measurements and conditions you can observe. GreyModule estimates the ductwork capacity from them.
