WEll i thought they where a great product but my H1001D propane heater has been nothing but trouble. Won,t lite now. I just spent 3 hrs tearing burner and all apart, blew everything out with air. Unit looks like new, but won,t ignite. I hear it clicking and took out igniter, i see a faint spark jumping across so i guess its ok. I have a 1000 lb tank and a regulator coming right off it into 5/8 coper line to another regulator and then into heater. The pressure i am recieving after second regulator is not much at all compared to right off the main tank . I am worried its not enough propane. Reading jump across TH gas valve TERMINALS with jumper, ok im lost.Without power going to it hows that supposed to work??? help frustrated in WV
