Rheem 84-MAS-1 Make-up Air System

The Make-Up Air System solves the sick house syndrome caused by too tight home construction. This unique system provides fresh air automatically, using no electricity or special controls, metering the air flow to keep the home balanced. The result is evenly distributed, tempered air that keeps the home fresh, the furnace efficient and the occupants comfortable. System consists of an Intake Air Hood which is installed through the wall to allow outside air in. The hood is connected via flexible 6 in. duct or standard duct pipe (not included) to the metering air device. The metering device effectively regulates the air inflow for proper air circulation, combustion and balance.
