How do you change propane in a Dometic furnace?
When you first change bottles or if you have had the propane turned off for an extended period, I always start by lighting the stovetop burners, first one until it burns steady, then all of them for a couple of minutes. From there I go to the water heater and sometimes it will take several tries. Next comes the furnace and last the refrigerator.
