D-28-6 Make-up Air Combustion Air Diffuser

The Skuttle Make-up and Combustion Air Diffuser (Model D-28-6) is designed to supply combustion air to fuel-burning appliances that have inadequate combustible air sources.

How the Diffuser Works

Generally installed 12 inches (30.48 centimeters) from the appliance’s combustion air intake, the Diffuser connects to a 6-in. (15.24 cm) 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.
