Approximate Air Settings are given in some
applications. WARNING: These are approximate
air settings. The burner must be adjusted using
combustion test instruments for the final air setting.
Failure to do so could result in burner or appliance
failure, causing potential severe personal injury,
death or substantial property damage. Follow these
four steps to properly adjust the burner:
Step 1. Adjust air until a trace smoke level
is achieved.
Step 2. At the trace of smoke level, measure the
CO2 (or O2). This is a vital reference point for
further adjustments.
Step 3. Increase the air to reduce the CO2 by
1 to 2 percentage points. (O2 will be increased by
approximately 1.4 to 2.7 percentage points.)
Step 4. Recheck the smoke level. It should be zero.
