b.  When checking a fuel pump’s operating pressure, 

a reliable pressure gauge may be installed in 
either the gauge port or the bleeder port.  See 
Figure 26A.

6.  VERIFY/ADJUST OIL PRESSURE for Riello 40 

burner. 

 

Adjust oil pressure.  Locate oil pressure adjusting 
screw and turn screw to obtain proper pump 
pressure, refer to Figure 8 and Table 9A.

  ADJUST  OIL  BURNER  WHILE  OPERATING.  

(flame present)
1.  ADJUST DRAFT REGULATOR for a draft of 

-0.02” (water gauge) over the fire after chimney has 
reached operating temperature and while burner is 
running.

2.  READJUST THE AIR DAMPER SETTING on the 

burner for a light orange colored flame while the 

draft over the fire is -0.02”.  Use a smoke tester and 
adjust air for minimum smoke (not to exceed #1) 

with a minimum of excess air.  Make final check 
using suitable instrumentation to obtain a CO

2

 of 

11.5 to 12.5% with draft of -0.02” (water gauge) 

in fire box.  These settings will assure a safe and 

efficient operating condition.  If the flame appears 

stringy instead of a solid fire, try another nozzle of 
the same type.  Flame should be solid and compact.  
After all adjustments are made recheck for a draft of 

-0.02” over the fire.

3.  READJUST THE TURBULATOR SETTING only 

if necessary.  

a.  CL3 through CL5

 

Move the turbulator setting forward or back one 
position at a time to optimize the smoke and CO

readings.

4.  Turn “OFF” burner and remove Riello Combination 

Pressure Gauge and Bleeder Valve Assembly.  
Install pressure port/bleeder plug and tighten.  Start 
burner again.

5.  FLAME  FAILURE

 

The CL Series boiler controls operate the burner 
automatically. If for unknown reasons the burner 

ceases to fire and the reset button on the primary 
control has tripped, the burner has experienced 
ignition failure.  Before pressing the reset button call 
your heating contractor immediately.

7.  CAD CELL LOCATION AND SERVICE

  The burner is supplied with a cadmium sulfide flame 

detector mounted at the factory, mounted on the 
bottom of the electronic ignitor. See Figure 27.  To 
service cad cell or to replace the plug in portion, 
swing open the ignitor. After service is complete, be 
sure to fasten down the ignitor.

  CHECK FOR CLEAN CUT OFF OF BURNER.

1.  AIR IN THE OIL LINE between fuel unit and 

nozzle will compress when burner is on and will 
expand when burner stops, causing oil to squirt from 
nozzle at low pressure as burner slows down and 
causing nozzle to drip after burner stops. Usually 
cycling the burner operation about 5 to 10 times will 
rid oil line of this air.

2.  IF NOZZLE CONTINUES TO DRIP, repeat 

Paragraph J, Step 1. If this does not stop the 
dripping, remove  cutoff valve and seat, and wipe 
both with a clean cloth until clean, then replace
