I only cleaned my glass once this year. That was just before Christmas.
The Stive was running.for over 15 min before taking the video (On Med/ it had been running.for over an hourtotal). The pellets can Never be see in the Pot, always in the very bottom and being burnt away as new ones drop. I am currently burning Presto Logs.
As for the Avatar? Thats the comment I made yesterday.
This is my 2nd full season with the Fahrenheit. Awesome furnace!! (See Signature). It has an awesome exchanger on it also (18 tubes, compared to the Quads 8 tubes. Although they are a smaller tube, and the Quads are larger.) About 50% of the air comes out of the 18 tube heat exchanger and the other 50% is blown around the firebox (taking the radiant heat away from firebox), so you get the best of both heat exchange worlds
Quad works great in the shoulder season weather. But when it gets cold, the ENTIRE house stays the same temperature with the furnace.
As for the Quad pot, it should be a very active flame and always emitting lots of little sparks. I would try another pellet for sure. But also look at ALL Factory seams and welds. The unit is mainly sheet steel, screwed together with high temp silicone as a seal? One little missed spot and Wa-La, an air leak? Or the ash pan gasket can be a PITA to check for tightness. Just how it sits in the stove, the dollar bill will feel tight. When in reality it isnt. Take a lighter and run it right against the crack around the ash pan, door, and factory seams.
