Classification: CPC F | IPC F

Claim 0:
1. An apparatus for heating a location, comprising:
a heating system and a controller, said system providing heat to said location, and said controller monitoring said system and having the capability to shut the system down;
an air supply conduit for feeding outside air to said system, said air supply conduit including a damper interchangeable between an open position and a closed position, said open position allowing said outside air to flow through said air supply conduit to said heating system, and said closed position preventing or impeding air from flowing through said air supply conduit to said heating system;
a sensor adjacent said damper and said heating system, said sensor in electrical communication with said controller, said sensor measuring a parameter correlating to, or representative of, air flow of said outside air to said system, and communicating said parameter to said controller, wherein said controller monitors said parameter and is responsive to a change in parameter, such that a predetermined threshold initiates a shutdown sequence of said system;
wherein said controller is programmed to determine whether a predetermined threshold value is met, said predetermined threshold value including a measurement of negative pressure, vacuum, air flow volume, or temperature within the heating system, as measured by the sensor.
