My 1979 Rheem furnace in my upstairs heater closet works well with 1/2 blue 1/2 yellowish pilot flame. Inside the door where it's housed is very hot to the touch and also the inside of the closet is heated up! I'm afraid to use my heater, could it be a fire hazard? What could cause the hot door and heat inside the closet? What should be checked?
I'm thinking it's hot like that because it's a natural draft unit most likely and is in a confined space. Seeing that it's almost 40 years old if you can, I'd consider budgeting for a replacement and definitely invest in a smoke/CO detector.
