in THE MAIN WALL
i was looking at a teledyne larrs boiler today that has its share of problems. one is that the boiler shuts off and immediatly tries for ignition again. its auto ignition, a S8600F1000 control. when i disconnected the wire from the burner ground terminal at the gas valve lug the system kept running. shouldn't it have shut down? i thought that the burner ground was how it senses the signal. there is no seperate sense wire. just when i thought i was seeing the light on automatic ignition, alas darkness. any help would be appreciated.

    Hi Gerry

    I am tied up on the phone with another tech right now on a no heat call he is on. I will get back to you later.

    It was probably

    grounding back through the pilot tubing. What kind of problems are you having with the Laars boiler?

    the burner lights,

    then about 10 seconds later goes out, relights, goes out, relights, then finally stays for a few miutes then does it again. i wanted to check the micro amps thru the burner ground wire, thats why i pulled it off the gas valve terminal, i expected the flame to go out. it didn't. if it was grounding back thru the pilot tube how does it get to the control? can it be measured?
