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.

oil flow is too low. Readjust for proper fuel
input, CO2 and smoke reading.



9. GRAY OR BLACK SMOKE FORMATION ON

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
