Hey. Thanks for all the helpful tidbits, all good to know. I have learned something else, potentially nearly a bombshell within this little soap opera melodrama. Someone told me that if the RV came from CA and the propane was filled in CA (yes, yes) then it has butane in the propane and the furnace will not work when the temp gets in the 30's because of this. That would explain a lot. Has anyone else heard this, and if so, what does on do to stay warm with a propane heater in CA?
If the above was/is true, then there is virtually no problem with the RV, short of having a fill of unideal propane/butane mix in the tank.
Butane has a higher boiling point than PROPANE
Propane------ has a -43 degree boiling point
Butane------- has a 30.2 degree boiling point
That means at 32 degrees or lower, BUTANE will not boil(turn from liquid to gas), so renders it useless below 32 degrees
BUT- Butane has NOT been available in the USA for RV Tanks and DOT tanks for almost 20 years. MEXICO still has Butane dispensary's. The plain fact is, it is not cost feasable for USA Gas fillers to have BOTH Butane and Propane storage tanks as Butane is not a desirable fuel. Butane is used for Gas Lighters and such. The plain fact is, you are OVERTHINKING your problem. As I stated, IF the rest of your LP appliances are working(Water Heater/Oven Range), then you have adequate LP supply. A SIMPLE test to check the LP regulator, is to Turn the top range burners ON. Watch the blue flames. Then fire up the Water Heater and then the Furnace. IF the range Burner flames flicker slightly or fully diminish, you have a LP REGULATOR problem. Replace it. Doug
