If the 5220 TEG is adjusted correctly, it will not emit excessive CO. When properly tuned,
the 5220 should emit exhaust with a CO concentration of less than 800ppm (air-free).
To tune the 5220 using a combustion analyzer, follow these steps:
Disconnect the customer load by opening the customer-installed circuit breaker
or fuse, isolating the TEG from any batteries, loads, or other voltage sources.
Check that the jumper clip on terminal block TB-1 is in the SETUP position
(between terminals 2 and 3). Move the jumper clip if necessary.
Mark the original position of the air shutter with a felt pen against the burner
cover.
Loosen the four screws mounting the air screen against the air shutter, leaving
the air shutter still in place.
Determine the required V

Take an exhaust reading with the combustion analyzer. Remove the analyzer
probe after taking the reading to avoid heat damage to the probe.
Use the following table in Figure 25 to determine the appropriate changes.
Repeat steps 5 and 6 as necessary until the TEG is tuned.
