PRODUCT DESIGN General Operation 3. Conversion kits for propane gas and high altitude natural and propane gas operation are available. See The GMV95 and GCV9 furnaces are equipped with an elec- tronic ignition device to light the burners and an induced draft High Altitude Derate chart for details. - Page 5 PRODUCT DESIGN High Altitude Derate 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.
