Abstract: A temperature probe is inserted in the stove pipe and connected to the alarm via an electrical conductor. The alarm unit is capable of triggering on either a "high" or a "low" temperature condition. The "high" condition represents the flashpoint of creosote, which is known as the cause of most fires in woodburning stoves. The "low" alarm is set to trigger at a temperature near the minimum required to maintain the fire so as to alert the owner that the stove is about to go out. In accordance with the present invention, it is possible to override this "low" temperature alarm when desired. The present alarm unit also contains a visual display of the current stove pipe temperature to allow the owner to adjust the fire conditions well before a dangerous situation arises.
