Multi-fuel Stove Design Blacksmith Artisan

Some Noted Design Features
of the Blacksmith Artisan
While writing the last post regarding inset stove efficiency, I was looking more closely at the photo I took of the Blacksmith Artisan with the door open, and I noticed a couple of features which might just have an impact on the overall efficiency of the convection section of the stove.
I have marked the two features in the above photo which I feel might just affect the airflow of the convection box.
FEATURE NUMBER ONE IN QUESTION
The top arrow points to the “air-wash” vent. The question I have in mind is where does this vent take it’s input. I suspect that it takes air from the convection air channel. If it dies this, it is doing two very wrong things:
(1) It might be mixing convection air with combustion air – this is a complete no-no in good stove design.
(2) By possibly taking warm air from the convection flow, it would at least be reducing the efficiency of the convection heater section of the stove.
FEATURE NUMBER TWO IN QUESTION
The lower arrow points to a large slot cut to accommodate the handle locking mechanism. This slot is about the same size as one of the air intake vents. If the slot is cut into the convection channel, which I suspect it is, it will at least cause turbulence in the convection air flow and reduce the efficiency.
If anyone has clear and concise answers to these two questions, I would be happy to hear and to possibly publish.
