Skuttle’s popular 216 Make-Up Air Control reduces unwanted air infiltration to provide added indoor comfort. Model 216-1 has a 6-in. (15.24 cm) diameter and is appropriate for most installations; Model 216-2 has a 4-in. (10.16 cm) diameter. Both models operate automatically and use no electricity.
An insulated flex duct connects the unit to a screened, fresh air inlet mounted outside the home. When the furnace blower operates, the air control damper opens, automatically drawing outside air into the furnace. The air is filtered, heated or cooled, then circulated through the home’s duct system. As a result, a slight pressure builds up in the home, keeping untreated air from seeping in around windows and doors.
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.
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.
