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 if "Zero".
The air/oil r
atio depends on accur
ate setting of the turb
ulator disc.
Be careful when making this adjustment as an incorrect setting will result
in an unsatisfactory installation. See figures 10A and 10B.
SETTING THE AIR ADJUSTMENT PLATE (See figure 11)
1. The hydraulic AIR SHUTTER (A) is operated by the HYDRAULIC
JACK (F), assuring complete opening of the combustion air intake.
Regulation of the combustion air flow is made by adjustment of the
manual AIR ADJUSTMENT PLATE (D) after loosening the FIXING
SCREWS (C and E). The initial setting of the air adjustment plate
should be made according to page 16.
2. The proper number on the manual AIR ADJUSTMENT PLATE (D)
should line up with the SETTING INDICATOR (B) on the fan housing
cover. Once set, the air adjustment plate should be secured in place
by tightening SCREWS C and E. 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 instal-
lation. Use instruments to establish the proper settings for maximum
CO
2
and a smoke reading of zero.
NOTE: Variations in flue gas, smoke, CO
2
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.
