FAQ
Will the Ascent Linear Premium 46 work when the power is out?
Yes. Its ignition has battery backup, so the fire lights without household electricity — a real advantage over electric fireplaces during winter outages. The blower rejoins once power returns.
How do you clean the glass on the Ascent Linear Premium 46?
With the unit fully cool, remove the glass front as shown in the manual and use a cleaner made for gas-fireplace ceramic glass — ordinary ammonia products can permanently haze the surface. Once or twice a season is usually plenty.
How much does the Ascent Linear Premium 46 cost per hour to run?
Its 24,000 BTU maximum input equals about 0.24 therms of natural gas hourly — roughly 35–40 cents at average U.S. rates, with lower flame settings costing less.
What opening does the Ascent Linear Premium 46 need?
Frame a minimum of 47.38 in wide x 39.38 in high x 18.96 in deep. The BLX46 itself is 47 x 39 x 18.31 in with a 39 x 14.13 in linear viewing area.
How is a linear fireplace like this different from a traditional one?
Proportions. The Ascent Linear Premium 46 spreads its flame across a wide, low 39-inch band for a modern presentation, where traditional fireboxes like the standard Ascent series use a taller, nearly square window with a classic log look.
Does the Ascent Linear Premium 46 have a damper?
No damper exists or is needed — the sealed direct vent system manages exhaust and intake automatically, and unlike an open chimney, it doesn’t leak heated room air outdoors when the fireplace is off.
What warranty backs the Ascent Linear Premium 46?
Napoleon’s President’s Limited Lifetime Warranty comes standard, and our authorized-dealer status means the factory honors it in full — see the Specifications tab for the model details (BLX46).
