PRODUCT DESIGN The GCVC9, GCVC95, GMVC95, AMVC95, ACVC9 and ACVC95 furnaces are equipped with an electronic ignition device 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 doors in place except for inspection and maintenance. These furnaces are also equipped with a self-diagnosing electronic control module.
PRODUCT DESIGN quired 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. High altitude kits are purchased according to the installation altitude and usage of either natural or propane gas. Refer to the chart above for a tabular listing of appropriate altitude ranges and corresponding manufacturer’s high altitude Natural Gas and Propane Gas kits.

PRODUCT DESIGN Coil Matches: A large array of Amana® brand coils are available for use with the GCVC9 and ACVC9 furnaces, in either counterflow or horizontal applications & with GMVC95 and AMVC95 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 92%+ and 95%+ furnaces match up with the existing Amana® brand coils as shown in the chart below.
PRODUCT DESIGN Thermostats: ComfortNet™ CTK01A* Thermostat Kit 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 Return air filters may be installated at the furnace side and/or bottom return openings.
