    Riello

    The only Riello I had a problem with had a bad flare on the fuel line. Redoing that (and adding a Tigerloop) solved that one.

    By the way, are you in Anacortes?

    Riello ignition

    The four normal ignition problems on riello in order...Faulty nozzle , electrode settings , burner settings or a cracked porcelain . Since your numbers look correct besides the high draft (breach I hope), drop the burner settings..
