FAQ

Does the Ascent Linear Premium 42 require a chimney or flue?

Neither. As a sealed direct vent unit it vents through one wall or roof penetration, drawing outside air for combustion — which is why it installs cleanly in homes and additions that never had a fireplace.

How hot does the front of the Ascent Linear Premium 42 get?

Like every operating gas fireplace, the glass gets extremely hot — well past 400°F — and stays warm after shutdown. A protective safety barrier is standard on modern direct vent units; keep children and pets back while it runs.

What does it cost to run the Ascent Linear Premium 42?

About 0.20 therms of natural gas per hour at the full 20,000 BTU setting — generally near 30 cents hourly at typical U.S. prices, making it an economical linear model to enjoy nightly.

What framing does the Ascent Linear Premium 42 need?

A minimum opening of 42.50 in wide x 39.38 in high x 18.56 in deep. The BLX42 measures 42 x 38.81 x 18.31 in overall with a 37.50 x 16.75 in viewing area.

Is a blower included on the Ascent Linear Premium 42?

Yes — the internal blower is standard, circulating the 20,000 BTU output into the room so the wide linear flame is matched by even, usable warmth.

Can I get the Ascent Linear Premium 42 for propane?

The BLX42 ships set up for natural gas. If your home uses propane, contact us before ordering and we’ll confirm the correct conversion path for this model so your warranty stays intact.

How long is the Ascent Linear Premium 42 covered?

It carries Napoleon’s President’s Limited Lifetime Warranty — their strongest protection — included in full with every unit we sell as an authorized dealer. Compare other sizes in our Napoleon fireplace lineup.
