To prevent air flow from central furnace
being directed back into the Add-on furnace:
A Backflow Damper is required in the 8” hot air
outlet pipe that connects from the Add-On
Furnace to the Central Furnace (see Figure 3).
We also recommend a 8” (eight inch), 90

required for installation) inside central furnace
