Abstract: A system for preventing ''''dry-boiler'''' failures which includes a float mechanism for detecting the water level in a heated reservoir and a device for testing the float mechanism to determine if it is operating properly and for preventing activation of the burner if improper operation is detected. If the float mechanism is operating properly but the water level is below a pre-determined safety level, then activation of the burner can be prevented and various alarms actuated to notify the operator.
