Field Testing of "Spillage- Resistant" Appliances
Chimneys are an endangered species in new Canadian houses. The combination of improved house airtightness and higher capacity exhaust appliances is increasing the extent of house depressurization. Chimneys have problems maintaining draft under high levels of house depressurization, resulting in spillage of combustion gases. A recent field test of over 100 appliances, such as gas furnaces, hot water heaters and fireplaces, showed significant spillage. Carbon monoxide detectors should be installed in the vicinity of these appliances to warn homeowners of the most dangerous spillage.
