SW6DE Hot Water Heater Operation

[RottieMom]

Sorry for asking so many dumb questions, I'll get past being a newbie in the near future. In the meantime...

Can someone help me out with the steps to follow for using the Suburban SW6DE (Direct Spark & Elec) hot water heater? I'd like to understand what steps to follow if using propane only, or electric only, or both propane and electricity.

I've read the operation manual, but am still a bit confused about steps and sequence. I know the first thing I'm supposed to do is once I'm hooked up to water (either city connection or fresh water tank & pump), I need to open the hot water faucets and fill the Hot Water heater tank.

Thanks for any instructions you can provide.
