F.REMOVE GUN ASSEMBLY

1.Items to be checked are nozzle size, type, and angle; head size (and setting on MD(V1)head); gun setting; and positioning of electrodes. This informations is shown in Figures 23 and 24 and Table 6 (at rear of manual).

2.Reinstall gun assembly.

G.ADJUST OIL BURNER BEFORE STARTING.

1.SET BURNER AIR BAND AND AIR SHUTTER, see Table 6 at rear of manual..

2.OPEN ALL OIL LINE VALVES.

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

4.REMOVE GAUGE PORT PLUG from fuel pump and install pressure gauge capable of reading at least 150 PSI.

5.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.

I.ADJUST OIL PRESSURE.

1.Locate oil pressure adjusting screw and turn screw to obtain 140 PSI pressure (100 PSI for V74R only).

2.DO NOT REMOVE PRESSURE GAUGE until later.

J.OTHER ADJUSTMENTS

1.ADJUST THE AIR BAND AND/OR AIR SHUTTER.

Adjust air supply by loosening lock screws and moving the air shutter and if necessary the air band. Refer to Table 6 for preliminary settings.

2.ADJUST THE COMBUSTION HEAD.

V72 thru V77; V713 and V714:

"L1" and "F" head burners have a fixed head which is non-adjustable. To check combustion head location refer to Figure 24.

V78 & V79:

“V1” (variable) head burners have the ability to control air by moving the head either forward or back.

Loosen the adjusting plate assembly hold down screw. Slide the head and plate to the required firing rate setting as shown in Figure 24. Tighten the screw and knurled nut.

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 24.

3.ADJUST DRAFT REGULATOR for a draft

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

4.READJUST AIR BANDS on burner for a light 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.
