I have been running my Quad now for three years and love it! Stove has run well! My question has always been why the thermometer (cheap Rutland kind....ya I know) showed lower temperature than all you guys talked about. I knew it might be 50 degrees off but ...... Merry Christmas to me. I bought a infrared thermometer. Now I realized the old thing was at least 200 to 250 degrees off! Now I can cruise at 600 - 700 degrees no problem!
