Figure 25A: Electrode Settings (Carlin EZ-HP)

G.ADJUST OIL BURNER BEFORE STARTING.

1.SET BURNER AIR BAND AND AIR SHUTTER, see Table 9 at rear of manual.

2.Inspect Beckett head setting on left side of burner by insuring the blue line MD(V1) or the line on the label MB(L1) are aligned, readjust if necessary. Refer to Figure 25.

3.Inspect Carlin head setting on left side of burner to ensure that the proper head positioning bar matches the nozzle that is installed in drawer assembly.

Replace bar if necessary.

Carlin burners for boiler models CL3-140 and

CL4-210 have the higher firing rate nozzle installed and two (2) loose nozzles with a head positioning bar kit attached to the nozzle line. Refer to Table

9 for proper nozzle size, air settings and fuel pump pressure setting based on desired firing rate.

If the desired firing rate is the lower GPH:

a.replace the factory installed high firing rate nozzle with one of the loose lower firing rate nozzles.

b.replace the factory installed head positioning bar with the corresponding head bar that matches the lower GPH nozzle installed, see Table 9.

c.change the factory air settings according to Table 9 and,

d.check the oil pump pressure and adjust if necessary to the setting specified in Table 9, refer to Paragraph H, Step 5 for details.

4.INSPECT RIELLO BURNER AIR DAMPER AND TURBULATOR SETTING, readjust if necessary, see Table 9a.

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

5.OPEN ALL OIL LINE VALVES.

6.Attach a plastic hose to fuel pump vent fitting and provide a pan to catch the oil.

7.OPEN FLAME OBSERVATION DOOR on front of boiler.

H.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 pre-purge is complete. Pre-purge prevents burner flame until 15 seconds has elapsed after initial power is applied to burner. During pre-purge, the motor and ignitor will operate but the oil valve will remain closed. Refer to Oil Primary Control Instructions for more details.

Figure 26: Adjusting Fuel Pump Pressure

4.ADJUST OIL PRESSURE for Beckett AFG burners (shut the burner off).

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.

b.Locate oil pressure adjusting screw and turn screw for appropriate pump pressure, refer to Table 9 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.

5.VERIFY/ADJUST FUEL PUMP PRESSURE for Carlin EZ-HP burners.

a.Turn “off” burner service switch.
