WARNING The United States Environmental Protection Agency (“EPA”) has issued various regulations regarding the introduction and disposal of refrigerants introduced into this unit.
PRODUCT DESIGN General Operation GME8 furnaces are equipped with an electronic ignition device used to light the burners and an induced draft blower to exhaust combustion products. An interlock switch prevents furnace operation if the blower door is not in place. Keep the blower access door in place except for inspection and maintenance. This furnace is also equipped with a self-diagnosing electronic control module.
PRODUCT DESIGN Accessibility Clearances (Minimum) High Altitude Derate Unobstructed front clearanace of 24" for servicing is recommended. When this furnace is installed at high altitude, the appropriate High Altitude orifice kit must be installed. This is required due to the natural reduction in the density of both the gas fuel and combustion air as altitude increases. The kit will provide the proper design certified input rate within the specified altitude range.

PRODUCT DESIGN Coil Matches: A large array of Amana® brand coils are available for use with the new GME8 furnaces, in either upflow or horizontal applications. These coils are available in both cased and uncased models (with the option of a field installed TXV expansion device). These 80% furnaces match up with the existing Amana® brand coils as shown in the chart below.
PRODUCT DESIGN Thermostats: NOTE: Complete lineup of thermostats can be found in the Thermostat Specification Sheets. Filters: Filters are required with this furnace and must be provided by the installer. The filters used must comply with UL900 or CAN/ULCS111 standards. Installing this furnace without filters will void the unit warranty. Upflow Filters This furnace has provisions for the installation of return air filters at the side and/or bottom return.
