The big fire that fits where big fireplaces don’t. Quick Facts • Heating Capacity: 550–1,100 sq ft• Viewing Area: 23 11/16″ x 41 11/16″.• Fuel: Natural gas; propane with a conversion kit.• Controls: Remote or wall-mount thermostat, both optional.• Fan: Optional Who It’s For A wide fire usually comes with a deep firebox, and not every wall or floor plan has that depth to give. So the fireplace gets sized down, and the focal point of the room shrinks with it. You need a wide fire that doesn’t demand a deep wall. If you want the biggest fire in a lineup built for tighter spaces—one that can heat a large living room and the space beyond it—the Napoleon Ascent 46 is the one. Pick a standard deep-box unit instead and the room gives up floor space it didn’t have to lose. What Makes It Special The Ascent 46 is the widest fireplace in Napoleon’s Ascent line, with a fire almost 42 inches across—big enough to be the focal point of the room, not a window into one. The hand-painted split oak log set comes standard, so from the couch it reads as a real fire, not an appliance. Here’s the quiet advantage: it still lights and keeps making heat when the power goes out—as long as you’ve kept batteries in the back-up, or you plug in your own power bank. The furnace quits with the grid; this room stays warm anyway. Possible Downsides • The heat-circulating fan is optional, not included—add the fan kit if you want warm air pushed across the room.• Remote controls and the wall thermostat are also add-ons; the base unit ships without one.• The beach fire, mineral rock, and woodland media kits need a separate support bracket. If you want a fire this wide without giving up the depth of the wall, the Ascent 46 is the right decision. The room it’s in becomes the room the house lives in. The Ascent 46 takes a Heritage or Zen decorative front, beveled finishing trim, and decorative panels from reflective black porcelain to Westminster, Old Town Red, and Sandstone brick—plus beach fire, shore fire, mineral rock, and woodland media kits—so the fire can match the room you already have.
