Unvented gas heating and hearth appliances are marketed in most of the US as energy-efficient. Previous modeling studies have shown that unvented products that are installed, sized, and operated according to manufacturersÂ’ instructions conform to reasonable IAQ standards and guidelines for CO, NO2, CO2, O2 depletion, and H2O vapor. Measured concentrations in some homes, as well as anecdotal evidence, have raised concern that unvented fireplaces may be a significant source of indoor air pollution.
