IMPORTANT
If using the system for both Draft and Combustion Air applications, perform the following procedure twice; first with

If the system is for Combustion Air applications, press the “Set Up” button on the Combustion Air (right)
side of the CPC-3.
The LEDs on the side associated with the application you selected will become lit and the display will read, "Inducer
Setup Set Installation" for Draft applications and will read, “Combustion Air Setup Set Installation” for Combustion Air
applications.

from the top line for Combustion Air, press the “Save Setting” button once.
If the CPC-3 Display shows the Set Point, Actual Pressure, and Percent Fan Speed in the top line for Draft
or in the second from the top line for Combustion Air, then do NOT press the “Save Setting” button; GO TO
STEP 4.
