I don't know what the 3 minute and 6 means, I have mine fully automatic, take a look.
Outside temperature almost 60
Inside the thermostat calling for 62 but it's 69 that's why the stove is idling
Glass temperature is 91.2
Body is 85.2
And exhaust is at 73
Sometimes I don't even see the flames,not even orange, but it always manages to restart.
