This is a used ITT gas control valve (Model number B69?) that was once used on my old Teledyne Laars pool heater. I have since updated to a newer electronic pool heater and no longer need this control valve. Frankly, I don't remember if I ever used it but I'm sure I may have. I don't know if it works. However, the red control knob still rotates. You buy as is. I have no way of knowing if it works or testing it.
