i have a pioneer back vent hook to a power vent. the power vent is approx. 1foot from the corner. i connected the baro damper directly to the stove installed a 45* on the baro and connected directly to the power venter. with this type of install it leaves about 1' of clearance from the rear corner of the stove not the hopper to the adjacent wall. from that point back towards the corner the walls very cool to the touch. the seperation distance increases from that point foward. seems to work great this way no problems since October. the flue pipe never gets hotter than 140* with pv.
