Oakville X3 overview
The Napoleon Oakville X3 Direct Vent Gas Insert (GDIX3N-1) is a step down in size from the X4, made for standard masonry fireplaces in living rooms and dens. It replaces an inefficient wood setup with a sealed gas fire that slides all the way to the back of the opening for a clean, built-in look.
The feature people notice first is Napoleon's NIGHT LIGHT, which gives the room a soft glow even when the burner is off. A full-view design opens up 340 sq. in. of glass, and directional baffles improve airflow so more of the heat reaches the room.
