4. Check for electrical wiring water pipes etc Inside the roof space cut the ceiling joists 45mm from the shutter opening This is to accommodate additional framing to support the joists once they have been cut Wa J Frame the ceiling opening using joist sized timber equal to existing joists to a minimum height of 100mm above the ceiling material Note Packing may be 3a required if the ceiling joists are only 75mm high 4 Using 100mm x 25mm timber for 600mm 760mm and 915mm dia fans or 200mm x 25mm timber for 1070mm or 1220mm fans build a platform to support the fan Hint If there is plenty of height above the fan build the platform higher for an even quieter installation The outside dimensions of your platform should be a minimum of 50mm greater than the outside dimensions of the timber plenum of the fan check measure the frame of your fan Hint Paint the platform and plenum timbers black so that light from the room will not show up the cut timbers when the shutter is open 5 Push the fan into the roof space via the framed ceiling opening Centre the fan s timber frame on to the platform and ensure it is level Toe nail to the platform using 50mm nails Remove the single screw on either side of the metal fan frame which holds it on to its timber plenum The fan will now float on its rubber packing to ensure no vibration Check that the fan frame is itself level on its own plenum Screw to be remove
