When Adjust the air damper when burner performance is in question.
Factory
settings Air damper: 0.126 in (3.2 mm)
Note: This parameter is factory-set.
Effects The air setting has the following effects on combustion.
■
Higher O
2
percentage (excess air settings) lowers soot production but raises
stack temperature and reduces efficiency: lean mixture.
■
Lower O
2
percentage (inadequate air settings) increases efficiency and lowers
stack temperature but may cause soot build-up: rich mixture.
Procedure Perform the procedure below to adjust the air damper.
1. Perform the initial setting of the air damper with the machine shut down.
2. Remove the burner. See topic Removing and Installing the Burner Assembly.
3. Loosen the screws (a) .
