Last night I started up my furnace for the first time this season and went through some routine checks to ensure everything is working properly (using the owner’s manual as my guide). I found two items that concerned me. I have a 9 year old Bryant 80% mid efficiency natural gas furnace.
The first is the shape of the flame coming out of the burner (see image burner_flame.jpg). In the installation and owner’s manuals, the flame is shown to come out of the 4 burner tubes. It looks to me as if the burner is leaking because the flame not only comes out of the 4 burner tubes but also between the tubes as can be seen in the photo. I can’t remember if the flame was the same last year or not. Is this normal or does the burner need replacing?
The second item is the rust spot that I pointed out in the photo rust.jpg. It is on the bracket that holds the burner in place. There is a similar rust spot on the bracket on the other side. I believe this is due to the flame not coming out of the burner properly because part of the flame hits the bracket exactly where the rust is forming. This makes me believe the flame was coming out of the burner the same way for at least part of last year.
Can anyone give me an opinion if this is normal or if I need to get someone to replace the burner for me?
