Napoleon Oakville X3: a dual burner gas insert with the blower and remote included
The Napoleon Oakville X3 is a direct vent gas insert made to replace an old, inefficient masonry or prefab wood burning fireplace. It needs an opening at least 29 inches wide, 21 inches tall and 17 1/8 inches deep. A dual burner fills the firebox with a triple flame pattern, and you can run the front and rear burners on their own. It puts out up to 30,000 BTU, and the heat circulating blower and the Proflame II remote come included. A split oak log set is standard, and Napoleon’s NIGHT LIGHT glows even when the fire is off.
One choice is required on the page: the decorative panels, in MIRRO-FLAME reflective porcelain or Newport or Westminster brick. Optional extras: birch or driftwood log sets, backerplates and faceplates in black or charcoal, a 3 inch riser box, and a 7 inch black cast iron surround. Order it for natural gas, or add the propane conversion kit. It vents through two 3 inch liners run up the existing chimney, one for fresh air and one for exhaust, and the matching Napoleon liner kits are on the page. Napoleon backs it with its President’s Limited Lifetime Warranty. The Napoleon Oakville X3 ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
