The numbers on the casting are there to denote the high and low end of the scale - in all cases the first mark is “Zero”.
The air/oil ratio depends on accurate setting of the turbulator disc. Be careful when making this adjustment as an incorrect setting will result in an unsatisfactory installation. See figure 9A and 9B.

SETTING THE AIR ADJUSTMENT PLATE
Note: For
1.Regulation of the combustion air flow is made by adjustment of the manual AIR ADJUSTMENT PLATE (4) after loosening the FIXING SCREWS (3&5). The initial setting of the air adjustment plate should be made according to page 13.
2.The proper number on the manual AIR ADJUSTMENT PLATE
(4) should line up with the SETTING INDICATOR (2) on the fan housing cover. Once set, the air adjustment plate should be secured in place by tightening SCREWS 3 and 5. For
3.The final position of the air adjustment plate will vary on each installation. Use instruments to establish the proper settings for maximum CO2 and a smoke reading of zero.
NOTE: Variations in flue gas, smoke, CO2 and temperature readings may be experienced when the burner cover is put in place. Therefore, the burner cover MUST be in place when making the final combustion instrument readings, to ensure proper test results.
