I have a Ruud Silhouette Gas Furnace, Model # UGDG-05EAUER and can't find the filter. I removed both panels on the front and nothing. It appears to be missing. It looks like it should have been under the blower, but I'm not sure. Can anyone tell me where it should be and what size I need? :confused:
I also noticed there is a little bit of sediment inside, how do I clean this out?
