Abstract
Combustion instability in combustion appliances may be recognized before excessive carbon monoxide may be produced. In some instances, combustion instability may be manifested in flame oscillation, or rather, in oscillations in flame intensity as measured, for example, by a flame sensor. If flame instability is detected, appliance operation may be corrected or terminated.
