A PG&E service person recently advised me that the 'Nox Rods' in my Ruud furnace were burned out. It seemed to be his opinion that they were unneccesary. I attempted calling a Ruud installer to get an answer but he referred me to the factory, I went to Ruud's web site to get a contact number & found that they provide no means of getting factory customer service (Not Friendly!).
So perhaps you can help - do I need these rods or not? There are two rods positioned just above the flames in each burner.
