Air Band; Primary Control - Sunfire SF-150 Service Manual

Air Band Setting
Note: The Air band should be set to approximately 1.25 - 1.5. Reducing the
air band to a lower level will reduce the amount of airflow to the flame
giving a higher concentration level of fuel that will raise the temperature of
the SunFire. However, if reduced too low, it can cause whisking – see Figures
4-1&2 for examples. Reducing too low can become dangerous. This can
easily be solved by increasing the amount of air within the flame by
increasing the level of the air band.
If the air band level is set too low, upon start up, you may notice some
smoke and a more noticeable smell of diesel.

Note: Will blink for a second before the green flame sense light turns
no. This simply let's you know the unit has been turned on and will be
calling for heat to produce a flame.
