8-7
8.7 — Oil Burner Maintenance
8.6.2 — Checking Failure to Light Main Flame
1.
Leave the gas pilot shutoff cock open.
2.
Shut off the main burner fuel supply.
3.
Turn the burner switch “on.”
The pilot will light upon completion of the pre-purge period. The main fuel valve(s) will be energized, but there
should be no main flame.
The fuel valve(s) de-energize within 4 seconds after the main burner ignition trial ends. The control will lock out
on a safety shutdown. The flame failure light (and optional alarm) will be activated. The blower motor will run
through the post-purge and stop.
4.
Turn the burner switch “off.”
5.
Reset the safety switch.
6.
Re-establish main fuel supply.
8.6.3 — Checking Loss of Flame
1.
With the burner in normal operation, shut off the main burner fuel supply to extinguish main flame.
The fuel valve(s) will be de-energized and the relay will signal the condition within 4 seconds. The control will
then lock out on a safety shutdown. The flame failure light (and optional alarm) will be activated. The blower
motor will run through the post-purge and stop.
2.
Turn the burner switch “off.”
3.
Reset the safety switch.
4.
Re-establish main fuel supply.
5.
The flame detector lens should be cleaned as often as operating conditions demand. Use a soft cloth moistened
with detergent, if necessary.
8.7 — Oil Burner Maintenance
The burner should be inspected for evidence of damage due to improperly adjusted combustion. Any soot buildup
on the diffuser or the oil nozzle should be removed. The setting of the oil nozzle in relation to the diffuser and
other components is important for proper firing and should be checked.
8.7.1 — Oil Strainers
Oil strainers should be cleaned frequently to maintain a free and full flow of fuel.
8.7.2 — Light Oil Strainers
The fuel oil strainer screen must be removed and cleaned at regular intervals. It is advisable to remove the screen
each month and clean thoroughly by immersing it in solvent and blowing it dry with compressed air. To remove:
1.
Loosen the cover cap screw, being careful not to lose the copper gasket. If necessary, tap the strainer cover gen-
tly to loosen.
2.
Check the cover gasket for damage and replace if necessary.
3.
Slip pliers into the cross on the top of the strainer and twist counterclockwise to remove the basket.
