For Oil Burners
1. Make sure the supply air fan is running.
2. Adjust the main oil regulator to supply the minimum pressure
required; see the Appendix for oil nozzle pressure drop information.
3. Turn on the atomizing medium and adjust atomizing pressure
to approximately 20 to 30 psig.
Note:
If using heavy oil as the fuel with either steam or preheated air
for atomization, then warm up the oil feed pipe and fuel oil
nozzle by running the atomizing medium through the burner
bypass valve. Leave this bypass valve open for 5 to 10 minutes.
4. If steam is being used for atomization, allow plenty of time to
drain the system of accumulated condensate and ensure steam
traps are working.
5. Verify that the main oil control valve is at its minimum open
position.
6. Light the pilot.
7. Open all manual fuel shut-off valves.
8. Initiate the ignition sequence through the flame safety.
9. Check that the pilot and main burner flames have ignited.
10. The oil flame should be a bright yellow color set inside the
refractory combustion block.
Note:
The first time that the burner is started, allow the refractory
combustion block to warm up slowly to reduce thermal shock.
Refer to “Installing and Curing Refractory Block” in Chapter 3
for details.
If necessary, adjust the main control valve’s minimum open position
to obtain the desired low fire setting.
For Gas Burners
1. Drive the main gas control valve to high fire.
2. Measure the gas pressure drop at high fire and compare to the
appropriate chart in the Appendix. If the maximum input is not
4-4
Step 6:
Adjust low fire
Step 7:
Adjust high fire
