Fig. 52 Burner head adjustment
6.4.5 Boiler lock out indicator on:
If the burner fails to establish a normal firing pattern or flame failure
occurs the flame monitoring photocell mounted in the burner body will
alert the burner control box to shut the burner down and provide a safe
lockout state indicated by the illumination of the lockout indicator [1].
▶ Wait 2 minutes then press the lockout reset button [1](see
figure 53) to initiate another start sequence.
▶ Repeat procedure until a flame is established.
Fig. 53 Reset button
▶ Start and run for 3 minutes then switch off.
▶ Release the burner retainer nut.
▶ Remove the burner.
▶ Check for after-spurting from the nozzle, indicated by oil saturation
on the combustion head [2] figure 55.
If after-spurting occurs:
▶ Remove the combustion head [2] figure 55 and electrodes, hold the
burner vertically, unscrew the nozzle and fill the nozzle holder with
kerosene.
▶ Refit nozzle, electrodes, combustion head [2] figure 55 and burner.
▶ Restart and run for 3 minute intervals until after-spurting stops.
6.4.6 Combustion checks
▶ Start and run the boiler for 20 minutes
▶ Remove sampling point plug [1] to check the smoke reading is
between 0-1. If the smoke level is above 1, check the combustion
settings are correct and the oil nozzle is in good condition.

▶Check the CO
2
levels and adjust the air shutter [6] figure 55 setting
according to the table opposite.
▶ Check the flue gas temperature is close to the values shown in the
table 9 on page 32.
▶ Turn off the electrical supply.
▶ Isolate the oil supply to the burner.
▶ Remove the oil pressure gauge.
▶ Refit the blanking plug [4] figure 55.
▶ Check and rectify any oil leaks.
▶ Switch on the oil supply.
▶ Switch on the electrical supply.
▶ Restart the boiler and run for 5 minutes.
▶ Recheck the CO
2
levels and if required, adjust the air shutter setting
[6] figure 55 to obtain the correct CO
2
level.
▶ Refit the sample point cap (hand tighten only, do not over tighten)
and refit the burner cover.

Smoke readings may be inaccurate until the smoke from
burning organic binder in the access door insulation has
ceased.
If the flue gas temperature is too high and the baffles are
correctly fitted, then reduce the oil pump pressure [3]
fig. 55, 5-10 p.s.i. to compensate for nozzle variations.
If the pump pressure has been changed, the CO
2
levels
must be rechecked and air shutter adjusted if necessary.
