TROUBLESHOOTING SUGGESTIONS

OIL BURNER (con't)

4.OIL FLAME IGNITES, BUT THEN FLAME SAFEGUARD CONTROL LOCKS OUT ON SAFETY:

A.Flame scanner lens dirty. Remove and clean.

B.Scanner sight tube blocked or dirty. Check and clean.

C.Flame scanner defective. Replace.

D.Fuel/air ratios incorrect, resulting in unstable or smoky flame causing scanner flame sighting problem. Readjust ratios for clean stable flame.

E.Defective flame safeguard amplifier or control. Replace as appropriate.

5.OIL FLAME EXTREMELY SMOKY AT LIGHT- OFF OR IN LOW FIRE POSITION:

A.Defective or incorrect size oil nozzle. Replace.

B.Fuel/air ratio incorrect. Readjust.

6.LIGHT-OFF OIL FLAME IS ESTABLISHED AND PROVEN, BUT BURNER WILL NOT ATTEMPT TO GO TO THE HIGH FIRE POSITION:

A.Low/High/Low or modulating burner high fire temperature or pressure control could be defective or not set to call for high fire. Readjust or replace control.

B.Loose wires or incorrectly wired. Verify wiring and tighten all connections.

C.Flame safeguard control or high fire switch (if supplied) defective. Verify and correct as required.

D.Hydraulic oil cylinder defective. Replace.

E.Linkage mechanically binding. Readjust linkage.

7.LOW OIL FLAME IS ESTABLISHED AND PROVEN, BUT FLAME OUT OCCURS IN TRANSITION FROM LOW FIRE TO HIGH FIRE:

A.Defective or incorrect size oil nozzle. Replace.

B.High fire oil pressure too low. Readjust.

C.Air dampers set too far open at low fire, which causes flame to blow out during transition to high fire. Readjust dampers.

D.Oil pump coupling loose or defective. Tighten or replace.

E.Defective oil pump. Replace.

F.Linkage mechanically binding. Readjust.

G.On modulating systems-fuel/air rations set incorrectly, causing flame to blow out when going to high fire. Readjust linkage.

8.WHITE SMOKE FORMATION ON OIL FIRING:

A.Oil/air ratios incorrect due to excess air, or oil flow is too low. Readjust for proper fuel input, CO2 and smoke reading.

9.GRAY OR BLACK SMOKE FORMATION ON OIL FIRING:

A.Impingement on cold combustion chamber surfaces due to incorrect oil nozzle spray angle for application. This could also result in carbon formation on chamber surfaces.

B.Defective or dirty oil nozzle. Replace or clean nozzle.

C.Incorrect oil/air ratios. Readjust burner to correct CO2 and smoke levels.

D.Oil pressure too low resulting in poor atomization. Readjust.
