This unit is the second one i purchased in a 1 year spread. I have an approx 2200Sq ft. house with cathedral ceilings throughout 80% of my home. i researched and originally cheaped out using an in line duct fan "useful as a poopy flavored lolly pop" it did not move anything.
Once smartened up, i used 2 14x14 return ducts with filter grills for the intake at the highest point on the wall in the wood burning stove room, i used 7x14x8 vents in the rooms to receive the warm air from the stove room and ran approx 25-40 ft. of 8" insulated flex duct to connect the intake to the vent to 2 ends of the house (my daughters room and the master bed room) once i found the location for the centrax's, approx midpoint in the flex duct, i cut the flex and mounted the centrax's and installed 1 -8" round metal duct to each end of the centrax's with 1/2 inch self tap metal screws and applied duct caulk to the metal plastic seam. slid the flex over the metal duct and finished with duct tape. now on to the wiring, from each fan to the predetermined location's of a thermostat's in each bedroom, i ran a length of 14/2 wire from fan to hole in the bedroom walls. from the attic area, i located a hot lead placed a 4x4x2 electrical box and connected 2 lengths of 14/2 wire from the box to each fan. in each bedroom, instead of a simple wall switch, i choose a single pole in line voltage thermostat (commonly used for electric baseboards) i connected the thermostat's as the switches so i could set the temps to my desired temp and they would only activat the fans when the temps dropped below 72". back to the attic. from the thermostat i connected the black lead to the hot black lead of the attic electrical supply. i then connect from the thermostat, the white lead to the hot black lead in the centrax, Thus the closed circuit and thermostat as the switch. Then the white common from the eletrical box in the attic to the white common in the centrax. The ground from the electrical box in the attic to the ground in the centrax and ground from the thermostat. This thing is a monster and makes zero noise except the noise of the moving hot air. i now use no oil when the stove is loaded no matter how cold it is outside. myself and my daughter can choose 2 completely different temps in each of our bedfooms and all are comfy. when choosing to redesignate the wires in your home, it always wise to use color coded tape in the connection areas so when you move, nobody runs into any surprises. i am not an electrician, nor am i suggesting the above is code or safe, i will leave that up to you to hire an electrician to verify the above. good luck, this was a plan in the works for years and boy am i satisfied.
