2.Direct vented – Take a draft reading from the inspection port of the boiler. This over-fire reading will be a positive pressure. Approximate over- fire draft readings can be found in the burner settings table.

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 Set-up – The air settings shown in the table are approximate. The burner must be adjusted during actual field installed conditions. Failure to do so will result in poor boiler performance and nuisance service calls. After proper draft and oil pressure have been established:

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.
