They must be supplied with all the steam they need without restriction, and all the filtered water they need without restriction and air free.
The steam valve should be fitted as close to the top of the boiler as possible the steam should be as dry as possible.
All the pipe work needs to be carefully bent so as not to crush the pipe, and bends need to be as long as possible – no sharp bends.
When boiler is up to pressure, turn on water until it dribbles overflow and then turn on the steam. When it picks up its then simply a question of balancing water / steam.
The water supply should be as cool as possible. Side tanks and saddle tanks tend to make the water too warm, so a tender supply is preferred.
Rubber connections can be a problem as can they collapse, because the injectors create a vacuum.
