2)change the factory air settings according to Table 6 and,

3)check the oil pump pressure and adjust if necessary to the setting specified in Table 6, refer to Paragraph F for details.

5.Riello Burners

a.OPEN ALL OIL LINE VALVES.

b.Provide a pan to catch oil.

c.Remove pressure port/bleeder plug from fuel pump and install Riello Combination Pressure Gauge and Bleeder Valve Assembly.

d.OPEN FLAME OBSERVATION PORT COVER on burner swing door.

F.START OIL BURNER.

1.Open vent fitting on fuel pump.

2.TURN ‘ON’ BURNER service switch and allow burner to run until oil flows from vent fitting in a SOLID stream without air bubbles for approximately 10 seconds.

3.Close vent fitting and burner flame should start immediately after prepurge is completed. Prepurge prevents burner flame until 10 seconds has elapsed after initial power is applied to burner. During prepurge the motor and igniter will operate but the oil valve will remain closed. Refer to Oil Primary Control Instructions for more details.

4.Adjust oil pressure.

a.When checking a fuel unit's operating pressure, a reliable pressure gauge may be installed in either the bleeder port or the nozzle port. See Figure 26.

Figure 26: Adjusting Fuel Pump Pressure

b.Locate oil pressure adjusting screw and turn screw to obtain proper pump pressure, refer to Table 6 at rear of manual.

c.To check the cutoff pressure, deadhead a reliable pressure gauge onto the copper connector tube attached to the nozzle port. Run the burner for a short period of time. Shut the burner off. The pressure should drop and hold.

d.Remove the gauge and install bleeder port and/or reconnect the nozzle port line.

G.ADJUST OIL BURNER WHILE OPERATING. (flame present)

1.ADJUST DRAFT REGULATOR for a draft of

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

2.READJUST THE AIR BAND on burner for

alight orange colored flame while the draft over

the fire is —.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 CO2 of 11.5 to 12.5% with draft of —.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 —.02” over the fire.

3.READJUST THE HEAD SETTING only if necessary.

Beckett Burners

a.V82 & V83:

Beckett MB(L1) Head burners have a fixed head which are non-adjustable.

b.V84 thru V89:

Beckett MD(V1) (variable) Head burners have the ability to control air by moving the head. It might be necessary to move the head forward or back one position at a time to optimize the smoke and CO2 readings. See Figure 27A.

Carlin 102CRD Burners

a.V87 through V89

The Carlin 102 CRD-3 Burner has the ability to control air by moving the head. It might be necessary to move the head forward or back one position at a time to optimize the smoke and CO2 readings.

b.If the fire is a little too rich, move the combustion head slightly forward by increasing dimension “A”. Refer to Figure 27B.
