    Pitco 45C+

    I have two Pitco's going off on HL
    Both are acting identical where as thermostat is sticking (burner stays on when stat is satisfied, and when temp is turned down).
    I condemned the t-stats on both, but one of my customers swears new stat was installed previously with same results. I am now second guessing my diagnosis on both (same models, different customers).
    Am I correct in assuming that GV stays open and t-stat opens gas flow?
    Is there a Pitco manual more in depth on the gas train/operation?

    TIA

    Scratch that
    Found some info, looks as if t-stat operates gv with pressure.
    I'll troubleshoot a little further. Both seem to only malfunction periodically, hope I can catch it!

    Sounds like a bleed-type combination valve with a GS type tstat.

    As my own special little tool, I once rigged a ball valve with fittings to pipe in where tstat goes to test the combination valve. Been awhile, but I think the tstat closes to stop flow of bleed gas through it and back to the combination valve - thereby shutting off main burners. That allowed me to place scrutiny on the combination valve ONLY. If I shut it off the ball valve and the burners stayed on, then the combination valve is faulty. Sometimes it took awhile and numerous on/off cycles to catch it.

    However, make sure your source & operating gas pressures are good first.

    Good info
    Valve closed should turn burners off within 15 sec
    Would still like to see the breakdown and operation of the gv.
    Btw: I went back to one and verified faulty stat.
    Will check the other one (different location) tomorrow.
    Thanks for sharing the ball valve tool/trick!!!
