Heat shed is blowing warm air into shop

Well the heat shed is built, Baby Fisher is puking out heat, and duct work is connected to blow warm air into the shop.

Painted a 1973 Scout last night using this heat system and it worked very well.

My next step is insulate the heat shed tonight and to use 6″ flexible ducting to supply intake air to the stove so paint booth blower won’t effect air intake to stove.

Intake for paint booth air flow is supplied by two 16″ x 16″ vent holes in the floor of the heat shed.
