This thread started just as I had filled my propane, so I have been able to verify my LP usage:

1st night: Turned furnace on at 6PM to 64 degrees and down to 62 at 9PM, the low was 34 degrees. Shut down the furnace at 6am.

2nd night: same

3rd night: Turned furnace on at 6PM to 66 degrees and down to 63 at 9PM, low was 26 degrees. Again shut down furnace at 6am

Filled the tank with 4.4 gallons.

I also placed a digital thermostat on the glass panel above the temperature sensor by the back window. When the furnace shut down at the 66 degree set point, the digital thermostat read 70 degrees. This morning, when I checked the digital thermostat it read 66 degrees.
