    CHECKLIST................46 reliability, or operation. The 58MSA Multipoise Condensing Gas-Fired Furnaces are CSA SAFETY CONSIDERATIONS (formerly AGA and CGA) design-certified for natural and propane gases (see furnace rating plate) and for installation in alcoves, attics, basements, closets, utility rooms, crawlspaces, and garages.

  • Page 4: Clearances To Combustibles

    INSTALLATION This forced air furnace is equipped for use with natural gas at altitudes 0 - 10,000 ft (0 - 3,050m), except 140 size furnaces are only approved for altitudes 0 - 7,000 ft. (0 - 2,135m). An accessory kit, supplied by the manufacturer, shall be used to convert to propane gas use or may be required for some natural gas applications. This furnace is for indoor installation in a building constructed on site.
