These “baffles” for the burners are in each tube of the heat exchanger. . .

Is this normal or a defect?

Those are Knox rods and are supposed to be removed if it is a propane furnace. If they are not removed they will melt.

Are they required to remain in a gas unit? This was a gas unit. What is their function?

Jeff,


Since you are in California I have heard that that state has strict NOX standards. If the furnace is operating on natural gas the I would say that the nox rod needs to be reinstalled in that burner chamber.
