The owner's manual and product brochure for the Trane XT 80 gas furnace can be downloaded from Trane's official website. The owner's manual acts as a guide for both air handlers and gas furnaces.
The owner's guide contains basic instructions for handling and maintaining the furnace for maximum efficiency and longevity, including ideal temperatures for operation, how and when to change air filters and a safety section for ensuring proper handling of the equipment. Additionally, there is a problem solving section to assist with identifying the cause and remedy for a number of possible issues.
