My Jotul is weak

That's key to the issue. Even in our F400 which was about .4 cu ft smaller, I burned thicker splits, typically in the 4-6" range. Skinny splits are going to combust faster due to the greater exposed surface area and increased number of air gaps between splits.

Which “should” give faster-higher temp burns, but shorter burn cycles ? What I’m hearing from y’all’s is the fuel has to season for three years etc. yes it absolutely does if you want to load thick long hardwoods.

Two shots of a fire as normally loaded early on in cycle full vent. BTW the idiot that designed to vent control “knob” needs to have his fingers burned in an open fire as punishment for not even having used his own design.
What I’m seeing is a middle section of Cat/ tube is not firing or not heating up as a result . I’m not sure how the “tube” cat relationship or timing works but I have noticed the cats will hear up and glow before good tube airflow ? Do I have that timing correct ?

Twenty minutes later :
Blower fan on 3/4 speed. (Speed control button broke off- so it’s a one speed unit now. Three calls to installer have yielded ZERO options as to replacement)
Temp up to 400*
