Finish pre-commissioning boiler checks
▶ Check the CO levels, refer to table 8 and adjust the air shutter [L].
2
▶ Check the flue gas temperature is close to the values in table 8.
If the flue gas temperature is too high and the baffles are correctly fitted,
then reduce the oil pump pressure [B] 5-10 p.s.i. to compensate for
nozzle variations.
▶ Turn off the electrical supply.
▶ Isolate the oil supply to the burner.
▶ Remove the oil pressure gauge.
▶ Refit the blanking plug [A].
▶ Check and rectify any oil leaks.
3. Switch on the oil supply.
▶ Switch on the electrical supply.
▶ Restart the boiler and run for 5 minutes.
▶ Recheck the CO levels and if required, adjust the air shutter
