||Incidents involving the escape of carbon monoxide from central heating boilers occur frequently. The purpose of this study was to evaluate suitable procedures for detecting leaks from the case and seals of pressurized central heating boilers. The following procedures were found to be suited: visual and tactile inspection of the case and seals; smoke tubes to produce smoke for flow visualization; smoke matches to produce smoke for flow visualization; ordinary matches and wax tapers to produce a flame for flow visualization. However, the use of a flue gas analyser is not recommended: it does detect the drop in oxygen concentration or the presence of carbon monoxide due to a leak of combustion products, but may miss the small changes from a boiler burning well but leaking only slightly.
