So, to troubleshoot and make sure that your furnace has propane running, you can turn on your stove in the rig and let it flame up for a few seconds, then shut it off. This should help clear out any air pockets in the line. The blower will come on when you turn to heat, but if your furnace doesn't have propane to light up/burn, then you won't have heat.
I'm assuming, also, that you have adequate amount of propane in your tanks and the valves are fully opened? Once you have ensured you have gas and the furnace still doesn't light, then you can have your furnace looked at by the dealer.
