Reset roll out again, set for Mike to come out tomorrow, tested gas pressure into unit and out. Then also with water heater on, adjusted gas pressure a bit. Went from 9.4, to 10.9 with everything running. Might want to add a low pressure cut off switch to prevent lp furnace form running if it is low on lp. Witch could help stop the soot problem. Also might need to do a cleaning if it is stopping the system from running correctly. Will know more after we do combustion test. Cycled unit on and off at tstat working for now.
