I have a clean out tee outside. The installer used silicone caulking on the bottom of the clean out tee cap. While trying to remove the clean out cap I removed all of the caulking from the bottom of the cap. I've since noticed a measurable difference in heat output. Should I re-caulk this area? This was not high temp silicone either. When I get home I'm going to give the stove a really deep cleaning to make sure there is no issues.
