Measurement of combustion products from a gas cooking stove in a two-storey house.

Tests were conducted in Ottawa during the winter of 1982/83 to investigate the effects of a gas cooking stove in the kitchen of an energy-efficient two-storey test house. Products of combustion: NO, NO2, CO and CO2, were measured in the kitchen, living room and bedroom in order to relate theinfluence of air infiltration and kitchen hood exhaust operation to the levels of air contaminants. Tests were also conducted, using the enclosed kitchen as a test chamber, to establish the values of emission rate for CO, NO and NO2and of reactivity for NO and NO2. An increase in air infiltration rate from 0.10 to 0.90 air changes per hour resulted in about 20% reduction in maximum levels for CO and NO2. Range hood operation also produced a marked reduction. Opening the kitchen window resulted in significant reduction in CO levels and, to a lesser extent, in NO2 levels.
