Abstract
A system for automatically shutting off gas flow to a furnace may include an inlet for supplying a gas to the furnace. The furnace may have a housing. The system may include a thermometer positioned inside between the furnace and the housing. A resettable limit switch may be in electrical communication with the thermometer. An electric shutoff valve may be positioned inline between the inlet and the furnace and in electrical communication with the resettable limit switch. A manual shutoff valve may be positioned inline between the inlet and the electric shutoff valve and may manually shut off gas flow to the furnace. When the thermometer reaches a predetermined temperature, the resettable limit switch may actuate the electric shutoff valve thereby shutting off flow of the gas to the furnace. The electric shutoff valve may only be re-opened by manually resetting the resettable limit switch.
