    yes we got rid of the full time pilot line, plugged it off at the old Petcock. We snugged the pilot assembly into the new valve. I was going to tie the vent line in, but then realized that thread was much smaller. I talked to RobertShaw, he told me it wasn’t necessary.

    The stat is a T87. If the system continues to act up, I’ll scrutinize that a little bit. The safety circuit is pretty basic, vapor stat, lower , and then thermostat or the other way around, it doesn’t really matter. It’s just a circle.

    I stuck my Seitron down its throat and the numbers were amazingly good. Super low CO.

    is that extra aluminum tubing a pilot lighter or is that just abandoned vent lines?
