FAQ

Is there a damper to operate on the Ascent 42?

No — sealed direct vent construction eliminates the damper along with the chimney. Exhaust and intake are handled automatically through the concentric vent, with no heated room air escaping when the unit is off.

Can the Ascent 42 run during a blackout?

Yes. The battery-backed ignition lights the fire without household power, so the B42’s 22,000 BTU stays available in an outage; the internal blower picks back up when electricity returns.

What does the Ascent 42 use in gas?

Approximately 0.22 therms per hour at maximum output — about 30–35 cents hourly at average U.S. natural gas prices.

What framing dimensions does the Ascent 42 need?

A minimum opening of 42.50 in wide x 35 in high x 18.56 in deep; the unit measures 42 x 34.63 x 18.31 in with a broad 37.69 x 23.69 in traditional viewing area.

How much room will the Ascent 42 heat?

Its 22,000 BTU output with the standard internal blower suits mid-size living rooms and dens as a zone heater — enough to let many owners drop the central thermostat during evenings.

How should the Ascent 42’s glass be maintained?

Clean the inner glass once or twice a season with a dedicated gas-fireplace glass cleaner after the unit cools completely — avoid ammonia household sprays, which damage the ceramic glass coating.

What warranty comes with the Ascent 42?

Napoleon’s President’s Limited Lifetime Warranty covers the B42, shipped with full factory backing because we’re an authorized Napoleon dealer.
