Does anyone have a picture of one of the old gas furnaces without a pilot safety system? That is to say, the pilot burner was not fed off the gas valve. It had its own manual valve, and was tapped right off the main gas line. That valve often had a handle shaped like the letter “B”. If so, and you have a picture of that setup, particularly the valve as it comes off the main gas line, would you mind posting it? Thanks.
You got me laughing on that one.
