Cool Seismic 4212 furnace question

Last night it got cold and when turning on the heater and setting the temp, the furnace kicked on and blew cool air out of the floor registers. For about two minutes. Then it shut off.
It wouldn't start up again until I slid the switch off/on at thermostat.

We have had this only two days, so I know this is probably user error. Can someone help us. We had a horrible time sleeping with that big pile of blankets.

Verify that the propane tanks are turned on, and full. The furnace will run for a bit before the air flow sensors open the gas valve and light the flame. If the lines are full of air and not propane it won't light and then shut off. Try the process a couple more times to purge the air. you can also turn on the stove to help purge the air.

Has it worked before? Sounds like the burner is not igniting the LP gas and it will shut off.
