Big E "furnace" with the small glass window. My flame licks the glass no matter what the draft is set at. Using heat #3 and thermostat with on/off mode. The glass is almost non-transparent after one burn session and all you see is a "glow" after a day of burning. Is this normal for all or is something out of adjustment? Burning Presto-logs at the moment which seem to be fine by me, good heat, no smoke, etc.
Also - there is no seal on the top and bottom of the glass, only the sides. Is this correct?
