REGULATION OF THE TURBULATOR AND AIR SHUTTER FOR PROPER COMBUSTION

Turbulator Setting

1.Loosen nut, 1, then turn the screw, 2, until the index marker, 3, is aligned with the correct index number.

2.Retighten the retaining nut, 1.

TURBULATOR SETTINGS - RIELLO 40 SERIES

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 F-3 and F-5 models, the air shutter is operated on a 120V 60 Hz. motor, the burner will not operate until the air shutter is in its fully open position; and for F-10 model is operated by Hydraulic Jack. (see figures 10 A & B).

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 F-10 model, manually open and release the hydraulic air shutter to ensure it has free movement.

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.
