Im using a couple grease screens I bought today to keep ash from getting into the smoke chamber of my cinder block smoker. I'm wondering if the screens can handle this? If they're only "rated" to a certain temp. only? The reason I ask is cause when I installed them today and test fired my smoker up to see how it worked with the screens I thought I smelled something a little off. Im not sure if just the "neweness" is burning off from the screens or what? I removed the plastic handles. Here are a couple pictures. The blue arrows is where the screens are.
