Couldn't disregard sorry
Not an expert but be careful:
-Flue must have sufficient movement/momentum during all phases, or else gases/embers might back up into the room late at night and hurt occupants.
-Flue stack must exist building to code, and must not be near other inlets.
-The custom rusty steel plate connection to the aluminum flue looks sketchy, and might be difficult.
-Wood Stove<-->Flue connection must be absolutely tight.
-CO/Fire alarm a must.
Don't mess around with fire/gases indoors.
