Smokebox Lima 2-8-0 - filling boilers with water procedur quesition

For those that run steam trains in advanced mode, I have a question on operation with getting water to the boiler.
Specifically for the Lima 2-8-0.
From the manual, the following shows the keyboard keys that is used.
- Live Injector Steam throttle - shift 9 (open)
- Live Injector Water Valve - L (open)
- Live Injector Lever - O (toggles open and close)
- Exhaust Injector Steam Throttle - Shift 8 (open)
- Exhuast Injector Water Valve - K (open)
- Exhuast Injector Lever - I (toggles open and close)
Are these steps in th correct order
1) Open the steam throttle. (that would be Shift 9) - this can stay open through out the journey
2) Open the water valve (that would be L)
3) Pull the injector lever (that would be O)
To stop water from entering I would close starting with 3, then 2.
When would I use the exhaust injectors (as the manual doesn't talk about it.
Also thre are the Blower and Steam blower throttle
To properly use the blower, I would open the Blower first then control the blower with the Steam blower trottle. (is that correct).
