I am assuming here based on your question you are new to RVng? As the fellas stated the propane is used to fire the furnace in your coach. Just like your gas forced air furnace at home uses either propane or natural gas depending on your location. At home your furnace blower is run by the 120 volt house current. In an RV the blower is run off the 12 volt circuit which is your coach's "house" battery. This allows the furnace to run when you are "off grid" not plugged into "shore power" which is the 120 volt electric at the park pedestal. When plugged into shore power your coach has a converter that charges the house battery and runs the 12 volt systems in your coach.
