Napoleon Oakville X4 Direct Vent Gas Fireplace Insert
The Napoleon Oakville™ X4 gas insert uses an exclusive dual burner split flow system that fills the firebox with a triple flame. The front and rear burners can be operated independently and modulate from 16,000 up to 40,000 BTU/hr input, and the full view design shows 518 sq. in. of fire behind heat radiating ceramic glass.
A heat circulating blower, Proflame II remote control and eFIRE controller are included, and directional baffles improve the blower’s airflow. The X4 comes with a split oak log set; decorative panels are required, and faceplates, backerplates and log upgrades let you finish it to suit the room. It is certified as a vented decorative gas appliance, vents through two 3" liners and is approved for mobile home installation.
