PRODUCT DESIGN General Operation Notes: AMV8 furnaces are equipped with an electronic ignition device used to light the burners and an induced draft blower to exhaust combustion products. 1. Category I Venting is venting at a non-positive pressure. A furnace vented as Category I is considered a fan-assisted appliance and the vent system does not have to be “gas tight.” An interlock switch prevents furnace operation if the blower door is not in place.
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.
