Professional installers affix the installation manual to the outside of the unit when they are done. These types of manuals represent the longest documents, in terms of page numbers, provided with the HVAC unit.
Technical manuals for Goodman furnaces include parts diagrams, an explanation of product serial numbers, dimensions and specifications. This document contains filter sizes for air flow, wiring sizes to ensure proper electrical connections and blower performance specifications to check for wear and tear on blower parts. Technical manuals help consumers and professionals when service must be performed on furnaces.
The repair parts manual lists every functional part of the furnace and corresponding parts numbers.
