mini-wini-dan Posted November 10, 2012 Share Posted November 10, 2012 I just replaced the the regulator for my lp gas system. I bought the regulator at an rv dealer and it is a 2 stage unit that as not a perfect match but did connect and after turning on gas was good for operating gas burners and the gas refrigerator. However when I attempted to run the furnace just the blower would come on and did not get ignition of the furnace burner. The gas bottle is the vertical type stationed under the vehicle in a closed compartment. It may be less than 1/2 full and am considering filling it up to see if that helps. Any thoughts on this problem? Is it possible that this regulator is the wrong type? Quote Link to comment Share on other sites More sharing options...
mini-wini-dan Posted November 12, 2012 Author Share Posted November 12, 2012 I consulted a local rv dealer and the mechanic advised me to run a burner while attempting to start the furnace. He said if the gas is low it would show a reduction in the flame. I turned on 2 burners and I did see one of them go out completely as the furnace fired up for the first time since changing to the new regulator. I will fill the gas bottle before I go on the road. I am sharing this for those who may have a similar problem. Quote Link to comment Share on other sites More sharing options...
90toydolphin Posted November 12, 2012 Share Posted November 12, 2012 if outside temps is low the pressure that builds up in the tank could be reduced to the point of not working???? Quote Link to comment Share on other sites More sharing options...
Maineah Posted November 13, 2012 Share Posted November 13, 2012 Propane boils at about -44 degrees so probably not. Usually propane tanks work until there is no more liquid to boil. Quote Link to comment Share on other sites More sharing options...
