Without seeing a photo of your unit, I am guessing that the switch you are speaking of is a "toggle style" switcl with a small hole drilled in it for inserting a pin. This switch is used to turn on/off the elecric heating element in the WH. The pin is used to keep you from accidentially switching the electric element on until you should - that being sure there is water in the tank.
There is no connection, either mechianilly (sp) or electrically between the propane side of the WH and the electric side, so you do not have to turn the gas off to the WH off.
And I will repeat what probably every poster here will say to you - That being do not turn the electric element on until you are certain the WH is full of water.
This topic is probably one of the most discussed ones here - do a search and you will get many hits.
Were you not told about this switch and what it does during your PDI?
