How Air Diffusers Work

Generally installed 12 inches from the appliance’s combustion air intake, the Diffuser connects to a 6-inch insulated duct, which in turn, connects to a screened, fresh air inlet mounted on the home’s exterior.  As the colder, heavier outside air enters the Diffuser, the unit acts as a check valve or cold air trap, automatically diffusing auxiliary combustion air into the area around the appliance.
