In this section, we have archived many of MIFCO’s old and current operating manuals for the convenience of our customers. You will need to have Adobe’s Acrobat Reader installed on your computer to be able to view the files. Just find your furnace’s model number in the table below and click on the link. The file will open in PDF format and can be printed on your printer. Some manuals are large and are divided into sections to speed downloading.  We encourage you to call our service department with any concerns- 217-446-0941 (6:30 am – 3:00 pm CST).
