unfortunately there is no standard way of "starting" a boiler but here is one to get you started, boiler recieves call for heat, pump starts, flow of water makes flow switch, this tells pcb to start fan, fan starts and makes air pressure switch, this sends signal to pcb to open gas valve and start spark,when flame is proved, spark stops and main gas valve opens and dont listen to the sparkys
OIL FIRING SYSTEM Fuel Oil Preparation Filtering the oil, Pumping the oil and heating it are the major ppp yreparatory functions. Filtration of oil in one or more stages to remove any dust, dirt, sediments, sledge etc. also forms part of preparation. This renders long trouble free service life to ppp,umps, valves and oil gun atomiser nozzles.

start-up and operation steam boilers warning: improper servicing and start-up of this equipment may create a potential hazard to equipment and to operators or persons in the building. servicing and start-up must be done only by fully trained and qualified personnel. caution: before disconnecting or opening any fuel line, or before cleaning or ...
Th operating burner should then be lit for low firing rate and efficient combustion ; The fuel oil flow should be matched with the speed of the fan to ensure a complete combustion with steady flame. Once the boiler starts and steam starts coming out of the superheater vents, the superheater header vents should be closed.
Please note: The above sequence of operation for both hot water and central heating are not identical for every boiler out there, however, the sequence of events will not progress any further forward, if there are no

of pressuretrols. Using the example of two boilers with low high low firing sequences, the pressuretrol settings can be arranged to obtain four different set points to meet the load demand. Assuming most commercial systems are two pipe steam systems that can sustain pressures anywhere from 2 psi to 14 psi, we can sequence the boilers on as follows:
