Experimental work to study the interaction between air extraction and open-flued - phase 2
The effective removal of combustion products through the flue of an open-flued gas appliance can be affected by a number of processes, eg blockage of the flue or inadequate ventilator air provision to the appliance. The operation of air extraction equipment in a property can also cause the combustion products to be inefficiently removed by depressurising the area within which the appliance is located and offering a preferred pathway into the property. Previous work was reported. Describes further work carried out to determine what factors contribute to this process in a full-scale domestic property, and produces some guidelines for the installers of gas appliances and extract fans.
