hope someone can reply..

does or can lp gas freeze.. a tank gauge says that there is 70 psi in tank... i start unit up ( bryant gas furnace ) and it does all normal things then inducer motor starts and then surface ingitor glows, then i hear a click ( gas valve opens ) it tries this for three times.. then i loosen the union on gas line and nothing comes out... The tank is approx. 100 ft from furnace.. gas ran through copper line... i think the gas line might have been not buried down i ground enough...

How can any condensation get into line..??

help
