When it first arrived it appeared to require a professional to install because the instructions required some contemplation. The outlet for plugging in the unit is already there, the location is ready to accept the unit, you just have to remove some of the fireplace to get the fan into place, but it really does fit even though it appeared unlikely at first. A few parts were missing but were quickly replaced without hassle. If you already have a wireless remote, the space is even tighter, but it fits and works fine. You definitely hear the fan but that's expected and the thermal activated fan only comes on when reaching temp and only shuts off after cooling which is acceptable and you can use switch to shut it off and regulate speed. We enjoy having it.
