Fix it into the ceiling opening, strap and tape the duct onto its spigot, then fit the diffuser from below. A good seal at the duct joint matters, as any leak here dumps conditioned air into the roof space instead of the room.\u003c\/p\u003e\u003cp\u003eCheck the direct vent diffuser size and the duct size you are running to this outlet against the 450 x 400mm listing before ordering.
