OK, The 10 Gallon Suburban Water Heater Manual is in the Files Section of the Forum.
1) The water heater only runs when the water needs to heat up (water temperature below 100 degrees).
2) It knows it needs heat, because the 12 volt DC power switch is on and the high limit switch is closed (Opens at 120 degrees). This sends 12 VDC power to the spark and propane control board.
3) The Control board sends 12VDC to the propane solenoid that opens and lets gas out into the combustion tube. It also sends a spark signal to the spark control and 12VDC to the "reset" light.
4) The control board will open the propane valve for 15 seconds to purge the gas lines prior to sending the spark signal.
5)The spark lights the propane and heats the water.
6) The board continues to provide 12VDC to the propane solenoid AND the RESET light until the high limit switch opens at water temp 120 degrees.
If no ignition, the board will re-try the light cycle. A light cycle is a 15 second purge followed by spark. It will do this 3 times and lock out the control board. It may take many cycles if the propane lines are empty.
If you turn off the gas when you are not using it; then turn the gas on and try to get hot water you may experience the symptoms you describe.
