Product Details:

The Napoleon Oakville X4 is a deluxe gas fireplace insert that offers all the quality features of the Oakville 3 but has additional BTUs for added heat. The Napoleon Oakville X4 generates up to 40,000 BTUs, a great solution to make any traditional open fireplace more efficient. The powerful 180 CFM blower is included and is paired with improved directional baffles to increase the airflow through the unit, maximizing the heat blowing out of the fireplace. The massive 518 viewing area provides an extraordinary sight that is unlike any other gas insert. The exclusive dual burner split flow system fills the firebox with a stunning triple flame pattern and allows you to independently operate the front and rear burner for your desired look. With the included Split Oak Log Set you get the feel of a natural wood burning fireplace without the wood burning mess.

The Oakville X4 includes Napoleon's exclusive NIGHT LIGHT detail that creates a warm glow throughout the room when the fireplace is off and adds more light in the firebox when the fireplace is on. It is equipped with Napoleon's eFIRE bluetooth remote control app for mobile devices. There is also a remote control included if the mobile bluetooth app is not preferred. Is the power out? No problem. The Napoleon Oakville X4 gas insert has an integrated battery backup that will allow you to light the insert in the event of a power outage.

The Napoleon Oakville X4 Gas Insert is very easy to install which makes it a great choice for DIY homeowners. It utilizes co-linear venting that consists of installing two 3" chimney liners for the fresh air intake and the exhaust. Simply connect the chimney liners to the exhaust outlet of the fireplace side and attach the liners to a co-linear chimney cap and the chimney venting is complete. If your home is off the grid and not connected to natural gas, a conversion kit is available to convert the insert to burn propane.

You can choose between the Mirror Flame, Old Town Red, Westminster Grey or Newport decorative fireplace panels to complement your decor. Optional faceplates and backer plates are available to seal around the fireplace insert and the opening of the fireplace. Choose the Oakville X4 fireplace insert for stunning full views of the fire while you get warm and cozy in the cold winter months.

    Optional Accessories


    Choose between the small and large black faceplate to close the gap between the insert and the fireplace so you do not have to see inside the actual fireplace.The faceplate is used when there is a smaller gap between the insert and the fireplace. The small faceplate will cover a fireplace opening less than 35 7/8" Wide x 24 3/8" Tall and the large faceplate will cover a fireplace opening size less than 40 7/8" Wide x 26 7/8" Tall.


    Do you have a larger masonry fireplace? Choose the large black backer plates. The backer plate is used when the masonry fireplace is larger and the faceplate is not able to close the gap between the fireplace and the insert. The backer plate can be used with the faceplate to add more dimensions to the insert while enhancing the look. The large backer plate can cover a fireplace smaller than 47" Wide x 30" Tall.

    Conversion Kit - Natural Gas to Propane

    Do you not have natural gas in your area? No problem. The conversion kit will allow you to connect propane to the fireplace insert. This is perfect for homes that are trying to live off the grid while still having a modern gas fireplace insert to enjoy. The conversion kit easily attaches to the fireplace providing an orifice to connect to a propane line.
