PRODUCT DESCRIPTION
Product Solid fuel central and supplementary hot air furnace
Brand Name Legacy Stoves
Description These are manual fed Coal fired forced air central furnaces. The furnace is connected to a remote mount room thermostat that signals the furnace when heat is needed.  When the heat exchanger reaches a pre-determined temperature, the fan control energizes the circulating warm air blower.  A high limit control is provided to shut off the fuel supply and combustion air in the event of an over temperature condition arise and or temperature regulator malfunctioned. When the room or wall thermostat satisfied the combustion air actuator will be in closed position. If the thermostat unsatisfied the combustion air actuator is in the opened position unless the fan limit control is above the high limit. So, the wall thermostat can turn the combustion air actuator on and off but, only if the fan limit control allows it. The combustion air actuator is opened by the wall thermostat but, the combustion air actuator is shut down by the high limit control.
