ABSTRACT:
A gas burner operation monitoring apparatus for enabling convenient diagnosis of gas burner and control problems. The invention is a temporarily attached device that collects and stores information concerning the key functions indicative of an gas burner's operation. If a fault occurs, the apparatus generates a signal to indicate to a downstream microprocessor, if such is connected, that a problem has occurred. This eliminates the need for the technician to randomly replace parts until the problem is located. The system monitors the status of the thermostat or aquastat; the presence and the level of voltage being sent to the main gas valve; the pressure of gas at the inlet and outlet of the main gas valve and either the temperature on the outside of the vent stack pipe or the presence and quality of flame at the main gas burner. The device also provides a signal in the event of a fault that can be connected to a downstream microprocessor that, in turn, can activate various warning devices.
