I have a new englander 25pdvc . Had it for a couple of years . I recently installed a rebuilt kit ,all gaskets and all motors .It starts up good after it been running you can see the fire drop down to nothing and then it will maintain . I had it go out when on 1 . Seems like it is starving for air. Changed from factory setting 951 to 541. It did run better . Went down the the 4 setting for fuel it almost went out . Any suggestions . The tech support at New England is great .i can't get through . I increased the fuel setting to 5 and went down a hour later fire out fan off ,no error codes .
