Misconception, Reality, and Uncertainty Regarding CO-Emissions From Unvented Gas Appliances


Because of the prolific use of residential carbon-monoxide (CO) detectors, there is a temptation to associate alarms, many false, with residential unvented-gas appliances. Manufacturers, users, and regulators need to know, with certainty, reliable information on the actual and possible levels of CO emitted by gas-appliances during normal use, malfunction, and misuse, and how these levels might impact indoor-air quality and safety.~(1-53) While many data bases are available on CO-emissions from indoor combustion sources, they are mostly compilations, with little commentary on consensus or quality. As the US Environmental Protection Agency (EPA) concluded, 'Given the prevalence of the source (~40 million),...and poor agreement between existing laboratory and field-derived CO emission data, there is a need to establish a better CO emissions database'.~(51) Moreover, it is suspected that the gas-appliance emissions data base 'harbors both random and consistent errors'.~(52) This paper critically reviews the extent to which [CO]-emissions from unvented ranges, ovens, space heaters, and hearth products is known with certainty. Data for this review were gathered from both the literature and new in-house measurements. As will be demonstrated, there is considerable myth, ambiguity, and confusion in the state-of-knowledge of [CO] from unvented gas-appliances, an indefensible situation that also plagues nitrogen dioxide (NO_2), another trace gas-appliance emission. Given the vital importance of knowing accurate CO-emissions data for gas appliances, to establish regulatory codes and performance specifications for detection and safety devices, the current state-of-knowledge is not acceptable. Actions are necessary immediately to remedy this situation, notably modern, periodic, and standardized measurement programs, whose procedures are well documented, controlled, executed, and validated.
