Jim, good article thank you. ^.^d
Hi Jim,
Thanks for the pictures, and info. This makes it easier to understand what's happening inside.
Thanks again,
Raymond
The author says to turn the tank valve off if you are refueling the main engine or are driving. I have never done this. I always make sure it is off and all appliances too when filling with propane. This means the fridge would not cool driving down the road. What is correct. I'm feeling stupid.
Dwayne,
Two issues:
When any combustibles around (i.e at gas station, refilling propane, etc) you do not want any spark or open flame. SO, refrigerator OFF at the refrigerator, furnace off, generator off, etc.
In addition, when filling the propane tank, both vapor and if you have it (your coach does) the liquid port as well.

Most Rvers keep the propane valve open and run the refrigerator on gas while driving. But the extreme safety conscious do not. Or they stay at home in bed.
I believe RV propane systems have an automatic shut off that senses excessive propane flow, as in an accident with ruptured propane lines.
Tom, ours is electric or 12v. Do you still have the risk if fire if its working ok?
Brett, thanks...I've only ever closed the one valve while refueling. I'll have to look but I'm thinking the other (liquid) valve doesn't have anything connected to it and is always off anyway.
Again, when refueling (not propane), turn the APPLIANCE off, not the propane at the tank. A refrigerator or furnace ignitor create sparks.
And, unless you have converted your generator to high pressure vapor, you generator runs on the liquid LP port.
You should be fine on 12 volts. No open flame and you can turn off the propane at the tank.
When I get my coach back with a 12 volt only compressor driven marine refrigerator I will probably leave the propane off at the tank unless I need heat, more hot water, or the stove and am without hookups.
