2.Direct vented – Take a draft reading from the inspection port of the boiler. This
3.Pump pressure – Install a pump pressure gauge in the oil pump following the oil burner manufacturer’s recommendations. Adjust the pump pressure as per the preliminary burner settings.
4.Combustion
a.Begin to close the air band to create a slight trace of smoke as noted on the Bacharach or equivalent smoke tester scale.
b.Take a flue gas sample and note the CO2 reading. It will be about 13% to 14%
c.Open the air band to reduce the CO2 approximately 2%.
d.Check for “0” smoke. Head settings and/or air band may be altered to obtain the above results. Lock the air band and head setting screws in place.
The above procedure will give a built in margin to ensure clean operation throughout the heating season. Should draft conditions vary, lint accumulate in the fan, heavier oil delivered, or other adverse conditions be encountered you will have a reasonable margin of built in protection before smoke generation begins.

Control Circuit Safety Checks
Check the safety controls on the boiler after completing the oil burner adjustments. A safety control check for satisfactory performance must be performed.
