How Make-Up Air Controls Work
The Skuttle Model 216 Self-Adjusting Make-Up Air Control is installed on the return air plenum of the furnace. Six-inch insulated flex duct connects the Make-Up Air control to a screened, fresh air inlet mounted on the outside of the home.
When the furnace blower operates, the damper in the Make-Up Air Control opens, automatically pulling the outside air into the furnace. The air is cleaned by the filter, heated or cooled, and circulated through the duct system. As a result, a slight pressure builds up in the home, preventing unwanted air infiltration around windows and doors.
