The whole face is glass, the whole view is fire. Quick Facts • Heating Capacity: 888–1,775 sq ft • Fuel: Natural gas or propane. • Controls: Remote and eFIRE mobile app included; wall control optional. • Fan: Included Who It’s For Most gas fireplaces put a metal frame and grille work between you and the flame, so from across the room you see an appliance first and a fire second. You need a fireplace where the fire is the whole view . If you’re building or remodeling a wall and want the fire to be the first thing people notice when they walk in, this is the one to look at—it builds into a framed wall, so plan on tile or stone finish work as part of the job. A standard louvered box will keep you warm just fine, but you’ll always know it’s a gas fireplace; the Altitude X is built so you forget. What Makes It Special The Altitude X has a clean face, which means your tile or stone runs right to the glass —no louvers, no frame, nothing interrupting the fire. Top lights inside the firebox shine down on the logs, so the hearth glows even before you turn the flame on, and the glass is ceramic, made to sit inches from a real fire for years. You run it from the couch or from your phone. The included remote and eFIRE app handle power, flame height, top lights, and fan speed, and a thermostat setting holds the room where you want it—set 70 and let it cycle. Here’s the part people ask about: it still lights when the power goes out , as long as you’ve kept batteries in the backup. It’s also one of the few fireplaces designed from the start for the wall above it. The optional Dynamic Heat Control system lowers the wall temperature with no fan running, so a TV or artwork can hang above the fire at the lowest clearances Napoleon offers, and ducted options can move the heat to another room—or outdoors—instead of stacking it on one wall. Possible Downsides • Battery backup isn’t self-contained —lighting the fire in an outage takes four AA batteries or a power bank, and neither is included. • Heat management is optional, not built in ; hanging a TV above at the reduced clearances means adding the Dynamic Heat Control system. • Media options are log sets only —driftwood, oak, or birch; there is no glass or stone media bed. If you want the fire itself—not the appliance around it—to be what people see, the Altitude X is the right decision. The room it’s in becomes the room the house lives in. The look is adjustable: driftwood, oak, or birch log sets; decorative panels in black illusion glass, MIRRO-FLAME reflective porcelain, or Newport and Westminster brick; finishing trims in black or charcoal; and Zen or Whitney decorative fronts.
